Stapler instructions and technical data. Furniture stapler - device, how it works, features of different types, how to choose the right staple, which staples to use? How to choose a furniture stapler? Instructions for use

A furniture stapler is a tool used to secure or fasten parts that are not very hard materials. Fastening is done using special staples for a furniture stapler. These staples come in many variations and vary in size, material and color depending on the job. There are also different types of furniture stapler, reviews of each are on the Internet. This tool has many different names (tacker, staple gun, staple gun, etc.). This is due to the fact that this tool is quite popular and widespread among the people.

Furniture electric and manual stapler: device and tips for choosing a tool

Not everyone knows how to choose a furniture stapler. It is worth noting that when choosing such a tool, you need to take into account that it has many varieties. Therefore, you need to take into account the operating parameters and characteristics of the technical parts with which you will work, as well as the furniture stapler device itself. Having studied all the nuances, you can go to the store and buy a furniture stapler.

A manual furniture stapler is a mechanical tool that is used with physical effort. The main advantage of a hand tool is its mobility and independence from electricity, as well as from other energy sources. The requirement of physical effort is the main disadvantage of a hand stapler, since with large amounts of upholstery work, a huge amount of time is spent. This fastening tool can be used only for partial or complete hauling of furniture at home, and not in factories with industrial volumes. These tools are best purchased from firms such as gross, matrix and similar firms.

An electric furniture stapler is a tool that works with electricity or a battery. It is best to use this type of unit for medium-sized upholstery work. The main disadvantages of this type of stapler are: low rate of fire of the mechanism, weak force of impact of the tool, as well as its rather rapid wear.

To work on an industrial scale on furniture upholstery, a pneumatic furniture stapler is used. Because it is fast, durable and strong compared to other types of similar building aggregates.

Furniture stapler video: how to use, how to charge, and what staples are needed

In order not to be injured by a furniture stapler, it is important to thoroughly understand how to use such a tool. If you are using a mechanical stapler, adjust the screw adjuster first. Adjustment must be made on the rough material, turning the regulator from minimum to maximum. If the fasteners are not included in the material from the first blow, then you will need to adjust your furniture stapler again, and if it does, then start working on the "clean copy". It is worth knowing in advance how to charge a furniture stapler. This can be read in the instructions for the unit.

To hammer the staples at the desired distance, it is best to mark such places in advance with a pen or pencil. You can also use a lock, which must maintain the same distance when driving in fasteners without preliminary marking.

Do not forget to also hold the material when making shots, so that the material cannot move out when driving the staple. Do not forget to also monitor the presence of braces so as not to be left without them at the most inopportune moment for you.

Secure the handle with a safety catch when not in use. This is due to safety precautions. When you follow these simple recommendations, you can easily cope with the upholstery of a sofa or other necessary task related to a furniture stapler, the price always depends on the type of tool and its manufacturer.

Furniture stapler, instructions for use: how to choose staples?

The instructions for the device have data on which you should rely in the choice of brackets:

The depth of the staples - it can vary from 4 to 14 mm. This parameter is determined by the nature of the upcoming work. For example, a tapestry on the back of a chair can be "shot" with 8 mm staples, and for felt you will need to use a depth of 10 - 12 mm.
Type - it all depends on the model, the labeling on the packaging should be the same as in the description for the device. For example, if the staples are small for a particular device, then they can "shoot" several pieces at a time. In addition, skewing of the staples in the tray is almost inevitable.

In addition, you should be wary of the seller's recommendation to replace one type of staple with another that is similar. Charges that are similar in depth may differ in geometry, which may be imperceptible to the eye, but critical in the operation of the stapler.

How to choose the right furniture stapler?

Are you wondering how to choose a stapler for furniture? Everything is very simple here: we make the choice based on what kind of work we have to do. So, if you need a device for upholstering a sofa or an armchair, then you can get by with a mechanical device, because furniture frames are usually made of soft wood. The effort given by the hand to the mechanical stapler will be quite enough for work.

If you have to work with harder materials, for example, chipboard, then mechanics cannot be dispensed with. An electric furniture stapler will have enough power. Pneumatic tools are even more powerful, but this is likely to be a waste of money. It makes sense to buy pneumatics for use in construction work.

A quality mechanical stapler, what is it?

Mechanical stapler, furniture, is not difficult. However, its design has features that affect the convenience and efficiency of using the device. Attention should be paid to the following:

Shop transparency. It is not at all critical for the functioning of the device, but it will be very convenient to control the number of staples.
Screw for adjusting the force of impact. Different density of wood and thickness of upholstery - regulation here will greatly facilitate the work.
Narrow working tip of a furniture, mechanical stapler. Provides greater accuracy in staple placement.
Stopper on the handle. This is a safety issue - you will be protected from accidental "shot".
Rubberized handle. Greater convenience when working, the device will not slip in your hand.

Electric furniture stapler: cordless or cordless?

The rechargeable furniture stapler is very convenient because the person working with it is not tied to the source of electricity. That is, you can work with the device even in the country, where there is no electricity. As a rule, the battery capacity is sufficient for quite a long time. Such a stapler has no obvious drawbacks, but it is worth purchasing it only if there is a need for wireless access.

In all other cases, it is better to choose a furniture stapler, electric, powered from the mains. And that's why:

The network device will have more power than the independent one.
Even the most capacious battery tends to run out.
The price for a network stapler is lower.
The weight of the battery device is higher, which means that it is more difficult for them to work for a long time.

How to use a mechanical stapler: how to charge the device?

How to use a furniture stapler is not difficult to figure out. But let's take a closer look at the charging process of a mechanically driven device.

We put the stapler on the fuse.
In the back of the device, we find a flap that covers the hole in the "clip" for staples and fold it back.
Pull the rod with the spring out of the hole.
We insert a block of staples inside, with "backs" towards the handle of the device.
We return the rod to its place, clamping the staples with it inside the stapler.
We lower the sash until it clicks. Then you can get to work.

How to use a furniture stapler: The video provides an overview of the mechanical model.

How to choose a furniture stapler to keep it safe?

For devices with any drive, mechanical or electrical, a button is required - a stopper that protects against accidental operation. Actually, such a stopper is quite enough for a mechanical stapler. But an electrical device, in order to be considered really safe, must also have protection against operation "idle". That is, the "shot" should occur only when the working part of the stapler is pressed against the working surface.

In addition to human safety, there is also the concept of "quality control of work". This is a very useful feature that will protect you from undetected flaws in your work. It consists in the fact that the electric stapler will turn off every time the staple is not fully hammered or crooked. So you can spot the defect in time and fix it.

How to properly fill the pneumatic furniture stapler?

Let's take a closer look at how to insert staples into a furniture stapler. The very first thing to do is to lock the device. So you will protect yourself from injury due to an accidental "shot". Further, the sequence of actions will be as follows:

We find and press the button responsible for opening the boat for staples. After pressing, either the tray cover will "slide off", or the tray itself will slide out of the handle. It all depends on the design of the model.
We turn the device over, once again make sure that it is locked.
We put the staples for the furniture stapler into the tray, with their "backs" to the device, and "legs" to ourselves. Make sure they lie flat.
We close the tray until it clicks.
Turn the stapler over with the working side away from you, remove the lock.

After charging, the tester needs to be tested. After that, do not forget to lock the mechanism again.

The furniture stapler is a fairly versatile tool with which you can not only perform the procedure for upholstering furniture, but also a number of other construction operations.

Today there is one that differs from each other in the principle of work:

pneumatic,
electric,
manual.

The pneumatic stapler is used in industry, and the electric and manual stapler are used in everyday life. Models belonging to the latter type are the most common in the furniture industry due to their mobility and ease of use. Let's take this example and consider the principle of operation, operation and repair of furniture staplers.

However, before proceeding to this procedure, I would like to say a few words about staples and their varieties.

The main indicator that is guided when choosing a bracket is its depth. Depending on the nature of the work performed, this indicator can vary from 4 to 14 millimeters.

So, for example, in order to carry out the procedure for upholstering furniture with fabric, a staple with a depth of 8 millimeters will be sufficient, while for fixing thicker materials, a bracket with a greater depth should be selected.

Also, depending on the overall dimensions, brackets are divided into the following types:

53 - is the most common. Staples of this type are 11.4 mm wide and 0.7 mm thick. The depth of this fastener varies from 4 to 14 millimeters;
140 - having the following characteristics: width - 10.6 mm, thickness - 1.2 mm, depth - similar to the previous type;
36 - such marking means that the stapler can shoot with staples that have a semicircular shape and are used mainly for cable installation;
300 - these are special nails intended only for the stapler.

When choosing a bracket, you should also take into account the structure of the material from which it is made.

Regular steel staples work well with regular wood. However, if you are dealing with chipboard or plywood, then you should get staples made of hardened steel, as regular staples can simply bend.

The manual construction stapler has a magazine into which a clip with staples or special nails is loaded. The striker strikes the bracket, which is attached to the striker. The size of the striker in the tool depends on the dimensions of the consumables (staples) used. The striker, in turn, touches the spring, the compression ratio of which is regulated by a special screw. Impact damping is carried out using a shock absorber, which is located inside the stapler.

See the stapler device in the diagram:

Coiled mainspring stapler device

The coil spring is installed on inexpensive models.

Manual stapler with leaf (spring) mainspring

The leaf spring stapler is more powerful and more expensive.

How to use a stapler

Refueling

In order to refuel the stapler with staples (i.e. charge the staple gun), you must first move the spring intended to press them. The staples themselves are placed in a special groove, in which, in fact, they must be placed. After that, the spring is put in place. The tool is completely ready for use.

Video: how to fill a stapler with staples

Now you know how to insert staples into the stapler, we can go directly to work.

Shot

In order to fix the necessary element, you should firmly attach the device to the place where you plan to drive the bracket. After that, without lifting the device from the surface, you must press the button (lever) of the trigger. In case of successful carrying out of these manipulations, you will hear a characteristic sound and see the bracket included in the material.

In order to protect yourself when working with a construction stapler, you should adhere to some rules:

In the case of using a mechanical model of the device, it is necessary to adjust the screw regulator. This operation should be performed on a piece of rough material by rotating the screw from minimum to maximum. If the bracket has entered to the end from the first shot, you can start working on the "clean copy". Otherwise, readjustment is required;
In order to drive the staples at the same distance, you must first mark the necessary places with a pencil or ballpoint pen;
Hold the material with your free hand so that when firing it does not move from a pre-designated place;
Keep track of the number of brackets in the "store" so as not to be left without a single fastener at the most inopportune moment;
After finishing work, fix the handle with a safety catch to prevent spontaneous or accidental shooting.

In addition to all of the above tips, you may also need help in repairing this construction tool, since the stapler, however, like any other equipment, tends to break down.

Repair

The most common cause of stapler failure is breakage of the striking mechanism... However, in order to get to it, you must first disassemble the instrument. This can be done by performing a number of simple operations:

Remove the adjusting screw;
Remove the spring;
Remove the protection cover;
Remove the pins;
Remove the lock washers.

If you do not understand how to disassemble the stapler from the list of actions, then you can see this in the video below.

After completing all of the above manipulations, you will be able to see the drummer, which, for the most part, breaks down due to the development of its resource.

In order to carry out the repair of this element, you should remove it, set it in a vice and, using an ordinary file, give the drummer its original shape.

That's it, the repair is over, and the tool is again on full alert.

Tips on why the stapler doesn't work and how to fix it:

If your tool does not shoot (does not finish off) the staples, then try to tighten the spring, it may have weakened;
If the construction stapler bends the staples, try adjusting the spring tension bolt (relax or tighten, experiment). Another probable cause of the malfunction is a mismatch in the type of staples with the structure of the material - for chipboard and plywood it is recommended to buy staples made of hardened steel;
If the staples do not come out of the stapler, but bend and get stuck inside, it is possible that the firing pin (tongue) that pushes them is rounded and needs to be sharpened;
If the mechanism itself works, and the staple does not fire, it may not capture the bracket, the firing pin has worn out. Try to file the firing pin and turn the damper on the other side.

Good luck to all home masters, if you have questions - write!

In construction, furniture production and minor repair work, a furniture stapler is often used. The device has several varieties and, if used correctly, significantly reduces the time for connecting certain surfaces to each other.

Furniture stapler device

The device that hammers staples into the surface has several names: furniture or construction stapler, stapler, staple gun, tacker and staple gun. All names are equally applicable in both writing and speaking. The tool is used to join together wood, plastic, film, plywood, insulation and fabric with special staples or pins.

You can find several types of tackers in stores, but the general principle of how a furniture stapler works is the same for all models:

All mechanisms are enclosed in a plastic or metal case.
The main component is the striking mechanism, which consists of a spring, a striker and a striker.
The shock absorber softens the recoil when fired.
The fuse protects against accidental firing of the staple.
The cocking handle or trigger is operated by physical force, electric current or compressed air force.
Any furniture stapler, the characteristics of which can vary significantly, has a special store with staples. Often it is made transparent so that you can visually control the amount of consumables.
The ramming mechanism provides the necessary entry of the stud into the surface.
The tip makes it easy to adjust the accuracy of each shot.
The force of impact can be changed thanks to a special regulator, thereby adjusting the stapler to work with surfaces of different hardness.

How does a furniture stapler work?

The working principle of the furniture stapler is based on:

Ejection of a fastener by the force of a compressed spring under the influence of physical force or electric current.
In pneumatic models, instead of a spring, there is a piston driven by compressed air.
After pulling the trigger, the energy of the spring or piston is transferred to the striker.
The percussion mechanism hits the bracket, thereby hammering it into the surface.
A furniture stapler is used to fix surfaces of different rigidity, therefore, before using the impact force, it is imperative to adjust the force to the material with a special adjusting mechanism, which differs for different types of tackers.

Types of furniture staplers

The correct choice of a furniture stapler is based on determining the frequency and duration of use, the type of surfaces to be joined. With these factors in mind, there are three types of staples available from the store:

Manual or mechanical tacker, which works thanks to the physical effort of the master. The tool has a simple design and the lowest price.
Furniture electric stapler gun similar to the mechanical version, however, an electric current drives the spring.
Pneumatic tool used by professionals when carrying out repairs or making furniture. Its design is significantly different from analogs, which increases productivity and cost.

Manual furniture stapler

The simplest and most often used in everyday life is a manual stapler for furniture. Its power is enough for independent constriction of sofas, chairs and armchairs available in the house, for carrying out minor repairs or making interior items. The main part of the percussion mechanism in a manual staple is considered to be an impact spring, which can be:

Twisted... It is installed in the most budget models and is considered less productive than analogs. The presence of a coil spring can be determined by the presence of an adjusting screw on the device body.
Leaf spring... Such a furniture stapler has greater performance and durability. The recoil in it is significantly less than that of the previous model.
Lamellar... Such a mechanism is used in professional appliances because of its high performance and price.

Electric Furniture Stapler

In electric models, the spring is not charged by the user by means of a special handle, but by a built-in electric actuator. Such a universal furniture stapler is convenient to use, because you do not need to exert physical effort to use it. Depending on the type of food, it happens:

Furniture network stapler powered by plugging into a standard household power supply. It is bought when repairs are constantly carried out in a room with an uninterrupted supply of electricity.
Cordless instrument that can be powered by replaceable batteries or a rechargeable battery. Its advantage is that the taker can always be taken with you and used where there is no access to the mains until it is completely discharged.

Pneumatic Furniture Stapler

The most productive and powerful furniture stapler is pneumatic. Its structure differs from the manual and electrical counterparts. A compressor or a special compressed air cylinder is connected to the device. After pulling the trigger, the air under pressure passes through the gas distribution unit, setting in motion a special piston mechanism. The latter transfers the force to the striker striking the bracket. Furniture pneumatic stapler is designed for professional use in large furniture industries and is more expensive than other varieties.

How to choose a furniture stapler?

Frequency of use... Do I need to re-tighten the old sofa once or regularly use the stapler for repair work.
Type of work performed... In furniture production, soft woods are used, which can be handled by hand tools. For construction, it is better to buy an electric or pneumatic tacker.
Versatility of the model... The cheapest staples work with only one type of staple. It is better to choose models for which different shapes and sizes of consumables are suitable.
Price... In hardware stores, you can purchase a staple gun at any level of income from the most budgetary models to expensive professional devices.

Furniture stapler - rating

Having decided which furniture stapler is best suited for a particular situation, you can analyze the reviews for each taker you like from ordinary users and professional craftsmen, or choose the model with the highest rating among which:

Furniture staples

After purchasing a staple gun, it is better to immediately stock up on consumables. Staples come in many different types. They differ in size, which each manufacturer marks independently. According to the material of execution, the staples are divided into:

aluminum, suitable for working with soft materials;
copper for soft wood species;
steel, suitable for any materials, but rusting over time;
made of stainless steel;
galvanized.

Depending on the type of work, you can purchase staples of different shapes:

U-shaped are considered standard and are used more often than other varieties.
U-shaped needed to fix the cable.
T-shaped are used when the fixation should not be noticeable.

How to use a furniture stapler?

Each device comes with clear instructions on how to use a specific brand of furniture stapler. Most of the recommendations are typical for all varieties:

All work is carried out in a clean and well-lit place in comfortable clothing, shoes and individual plastic glasses to protect the eyes.
Small working surfaces are fixed with a vice, and large ones are held by hand.
Before work, the furniture stapler must be filled with staples.
Then the electric models are connected to the network, and a cylinder or compressor is connected to the pneumatics.
The impact force of the device is being adjusted.
When the staple gun is set up, it is recommended to test its operation in an inconspicuous area.
The fixed surfaces are tightly pressed against each other, and the spout of the device is installed close to the place where you need to drive the staples.
The staple clogs after pressing the handle or trigger.
After completing all work, the device must be put on the fuse.

How to refuel a furniture stapler

The technology of how to insert staples into a furniture stapler, observing the recommendations of manufacturers and safety precautions, consists of several stages:

The tool must be locked with a fuse.
The magazine is removed or its lid is opened.
A rod with a pusher spring is obtained.
The rack of staples turns with the tip against the handle and is inserted into the groove.
The rod with staples is installed in the store.
The lid is closed and fixed.
The staple is removed from the fuse and adjusted.

How to set up a furniture stapler?

The tool does not need to be adjusted after each staple change, but only if:

First work after purchase.
Incorrect operation of the device.
Changing the material to a softer or harder one.

The principle of how to adjust a furniture stapler depends on the modification of the staple gun:

Coiled spring mechanical devices are adjusted by turning a special screw.
On devices with leaf and leaf springs, the regulator is located under the handle.
Electric and pneumatic tools are adjusted with special rotary mechanisms.

Experts recommend smoothly turning the regulator from minimum to maximum position, constantly checking the quality of the setting with test shots in inconspicuous places. The regulation is considered complete when the brace is completely straight into the surface, and its back remains on the surface, without going deep into it.

How to disassemble a furniture stapler?

If it is not possible to adjust the staple gun, then it is worth checking the serviceability of the main working elements. If the master knows exactly how to disassemble the stapler, then with self-repair it is worth taking off one by one:

adjusting screw;
shock spring;
protective cover;
pins;
lock washers.

After these manipulations, the main components can be easily reached and repaired or replaced if necessary. You need to assemble the furniture stapler in the same way in the reverse order. When it was not possible to identify or eliminate the malfunction, it is better to contact the service center to a certified technician.

Why does the furniture stapler not work?

The main malfunctions of a furniture stapler can be associated with improper operation, selection of staples or design features of a particular model:

If the staples are not completely clogged, then you need to either adjust the tool and tighten the spring, or remove the jammed staple from the magazine and continue working.
Often, if the staples are not clogged at all, grease the head of the staple pressure mechanism.
When the staple throws out several staples at a time or they constantly get stuck, this indicates a malfunction of the striker. Its shape may be damaged or there may be a crack.

Why does the furniture stapler bend the staples?

Another common problem is a situation in which a furniture stapler bends staples, which every experienced craftsman knows to do. The problem can be solved in two ways:

Buying more durable staples, since the existing ones are not suitable in terms of density to the material.
Using staples with shorter legs. The shorter they are, the easier it will be for the fastening material to enter the surface.

How to do without a furniture stapler?

There are not so many alternatives to replacing a furniture stapler in the construction market and they depend on the type of work performed. More often, such a tool is used for decoration purposes and to change the upholstery of upholstered furniture. Then the staples can be replaced with:

Small thin nails with nice heads that will have to be hammered in by hand with a hammer.
A special glue called "liquid nails", which, after drying, connects some surfaces no worse than metal fasteners.

When the question arises about hauling furniture at home or about carrying out other manipulations that require quick fixing of parts of objects that consist of soft materials, a construction stapler comes to the rescue.

The furniture stapler is a versatile tool with many modifications. With the help of this handy device, you can quickly sew together two equivalent materials or perform a number of other construction operations.

Basic principle of work the device consists in the operative stitching of the material using strong staples. Thanks to the convenience of using the construction stapler, work is performed much faster, and the appearance of the product being repaired is the most aesthetic.

Types of construction staplers

There are several main types of devices that differ not only in their technical characteristics, but also in the specifics of the tasks performed.

Manual or mechanical

The simplest and most convenient to use is a manual or, as it is also called, a mechanical stapler. It has a relatively small size, light weight and low cost. To work with the device you have to make a lot of physical efforts, insofar as in order for the parts to be fastened together, it is required to press on a special handle with a built-in spring. It is she who is the main element of the hand stapler, through which various pieces of furniture are stitched.

This type of device is most suitable for performing simple household tasks for hauling furniture at home. It is very difficult to wield the tool for a long time, since frequent pressure on the handle with a spring can quickly get tired, and it takes a lot of time to complete large volumes of work. In this way, this type of tool will be good for minor jobs where it is required to bond soft upholstery fabric to non-hard wood species.

Electric

If you need professional upholstery furniture, experts always use an electric stapler. This type of tool is perfect for the prompt execution of large volumes of work. The stapler for furniture works exclusively from the mains by connecting it to an outlet or from a plug-in battery. And while this device does not require any effort to operate, it has some other disadvantages.

So, for example, an electric stapler has a relatively low penetration rate and a low rate of fire. Moreover, this type of device, in comparison with mechanical staplers, breaks down very quickly due to frequent overheating. Modern instruments have a built-in indicator, showing how many staples are left inside the device, which is very convenient in the process.

Pneumatic

The most powerful and most effective are pneumatic devices. They are used in mass production of furniture. The pneumatic tool features durability, reliability, high sewing speed and practicality. To apply this type of device A compressor is always required, since the basic principle of operation is based on the supply of compressed air at very high pressure. The pneumatic stapler is capable of performing huge volumes of work in the shortest possible time.

This tool is used not only for hauling furniture, but also in other renovation or construction areas. However, for home use A handheld furniture stapler is ideal.

Application area

With the help of this unique tool, you can achieve high results in the process of performing such works as:

For simple jobs a manual stapler is ideal, while for large volumes it is best to choose an electric or pneumatic version of the device.

Advantages

The tool has a number of undeniable advantages, regardless of the type of stapler used:

It should be noted that a mechanical appliance should always be chosen for domestic use. It is easy to use and maintain and, importantly, has an affordable cost.

A huge variety of different types and modifications of staplers can unsettle an inexperienced consumer for a long time. Therefore, in order to choose the right device, you should be guided by certain rules.

Considering all the characteristics of the device, you can make a smart choice in favor of exactly the model that will be most suitable for your current needs.

Construction stapler: how to use

The device is quite simple to use. The main thing is to follow all the rules regarding charging the stapler:

Any master can manipulate with this tool, and there is absolutely no need to hone skills for this. The main thing is to properly load the stapler clip, after which you can safely start working.

I met two versions of the adjustment staplers, both had to be adjusted ...

I must say right away that all these instructions did not help much, I had to lime about a dozen staples in order to achieve the best result, and then readjust it every 15-20 strokes in the course of work. Therefore, the adjustment process is a constant action during use.

Another point - one builder advised to relax the spring after work so that there are no springs on it during storage, this is the reason that before each work it needs to be adjusted.

Option 1

The adjusting screw is located on top of the stapler; inside, along the entire length, there is a straight spring pressing on the firing pin. If the screw is tightened clockwise, the impact will be stronger and, accordingly, the clip will go deeper. By unscrewing the adjusting screw counterclockwise, the impact is weakened.

Option 2

In this version, the stapler is made by means of a leaf spring, it is she who presses on the firing pin and regulates the impact force. The adjusting screw is located under the handle. I don’t remember exactly in which direction you need to turn this screw, try it yourself. When you turn it, the plate bends and presses on the firing pin, or the opposite effect occurs.
