Bottle cutter for shrinking rope. DIY bottle cutter: manufacturing options Bottle cutter for a perfectly flat tape

We have to buy many simple things needed in the household. But you can make them yourself. It will save money, and a DIY item is always better. These things include a bottle cutter for cutting strips of various widths from plastic bottles. Such a device is always useful in everyday life, because it provides an almost unlimited supply of plastic rope. In addition, by using the bottle in this way, we, albeit a little, but make our ecology cleaner.

There are many different drawings and options that help you make a do-it-yourself bottle cutter. How to make such a device (the photo below is one of the options for a bottle cutter) is described in this article. Consider two manufacturing methods.

What is bottle cutter

So how do you make a bottle cutter yourself? At the heart of any design of such a device is a blade. Most often this is a blade from a clerical knife. It is very sharp, inexpensive and does not need to be sharpened. In the structure, on one side of the blade, some space is left, which determines the width of the ropes to be cut.

The bottle cutter can be made either manually or fixed. Such a device allows you to cut PET containers from food products practically without problems. To cut a bottle, you must first cut off the bottom. Next, an incision is made and a tape is already cut along it. As a result, depending on the width of the cut rope, from one to one hundred meters of material is obtained. And the bottle is almost completely consumed. All that remains is the neck and the bottom.

Simple option

What is the easiest way to make a bottle cutter? The easiest way to make such a device is as follows. The blade from the clerical knife is pressed with a clamp to the table or any other surface.

In order to obtain the desired width of the tape, a piece of plywood, wood or some other flat material of a certain thickness is placed under the knife, between it and the table. Its thickness will determine the width of the future tape.

A piece of similar material should also be placed between the blade and the clamp, as the blade may burst if squeezed with the clamp. And when cutting the tape, the blade can slide on the metal and create difficulties in the process.

Thus, it is clear how to make a bottle cutter for plastic bottles in a couple of minutes. But simplicity also has its drawbacks. First, when cutting, the tape is pulled with one hand, while the other hand has to hold the bottle. Secondly, the cut tape may not be completely even, since there is no reliable fixation of the size. And cutting a very thin line with such a device will not work.

Versatile and comfortable model

How to make the bottle cutter more reliable and versatile? To do this, you will need the following materials:

• Aluminum corner or U-shaped profile.
• The blade from the stationery knife.
• A piece of hairpin with a diameter of 5 mm.
• Two nuts M5.

A through hole with a diameter of 5 mm is drilled in the corner or profile. A hairpin is inserted into it. The blade is put on it through the hole. Then the blade is tightly fixed with a nut.

Next, cuts are made from the angle of the profile of various lengths. Their length will determine the width of the tape to be cut. The other end of the blade is secured with a clamp. If a U-shaped profile is used, then the second end of the blade can be fixed with a piece of board of a suitable width by inserting it with a rasp.

If you do it this way, you don't have to hold the bottle. It is simply put on the hairpin, and you can pull the cut rope with two hands. In addition, the cut strips will turn out to be even and will have a strictly selected width, and the blade will not have to be rearranged.

Application of PET tape

How to make a bottle cutter is now clear. But where to use the cut tapes? They can be used to hold just about anything. At the same time, if you warm them up with a hair dryer, the PET will shrink and the connection will become more dense and reliable. Also, these stripes can be used for baskets, bags and furniture.

Crafts from plastic bottles are associated with most people with not very attractive pigs from "five-liter", standing next to the rickety swans made of tires. I also remember the plastic bells and chamomiles, which are boring to everyone, "planted" on the flower beds instead of fresh flowers. Their frequent neighbors are discarded toys, "saved" by someone's hands and attached next to other garbage. Such "art" most often causes disgust and is in no way associated with something beautiful and useful. The lids and pieces of plastic nailed to the stumps can hardly be called beautiful or "made with love." Isn't it better to plant real flowers and trees on flower beds, and not fake them, and use plastic containers for more practical things?

How to cut plastic tape

People who are accustomed to "trash compositions" often do not have the idea that really beautiful things can be made from plastic bottles. You do not need to look for any complex adaptations for this. For most crafts, you only need a special tool - a bottle cutter to quickly make plastic tape of various widths. You can also cut the bottle with scissors, but this occupation takes much longer. Making a bottle cutter for plastic bottles with your own hands is not difficult. There are several options, the most popular of which is considered to be a machine made of an iron corner and a stationery knife blade.

Iron Corner Bottle Cutter

To make a simple do-it-yourself bottle cutter, you will need:

• corner of durable metal;
• a blade from a clerical knife;
• screws and nuts;
• die for threading;
• crank;
• steel pin with a diameter of 6 mm;
• hacksaw for metal;
• drill.

Bottle Slicing Machine Manufacturing Process:

1. The diameter of the steel pin should coincide with the hole in the clerical knife, therefore, on its lower part, you need to cut a thread using a die and a knob. The end of the pin should fit easily into the hole, but not slide out.
2. A hole of such a diameter is drilled in the corner so that the knife can be pressed tightly against it with a pin.
3. On the reverse side of the corner, using a hacksaw for metal, cuts of various sizes are made. Their size and depth will depend on width of the resulting tape from a plastic bottle.
4. All holes must be sandpaper on both sides of the corner, otherwise the tape will get tangled or unevenly cut, clinging to the edges of the metal burrs.
5. The inner parts are leveled with an awl and then sanded again.
6. It remains to assemble the structure with bolts, attaching the pin to the corner.
7. So that the knife blade does not move, it is advisable to add an emphasis for it from an iron bracket or a wooden block inside the corner.
8. The pin needs to be bent slightly to the side, then the bottle will be pressed against the corner due to its own weight.

Preparing containers for slicing

Before using a hand-made bottle cutter, the container should be cleaned of labels and glue with a knife or in any other way. Then the bottom is cut off. The edges must be carefully trimmed with scissors. It is advisable to fix the bottle cutter vertically in a vise, otherwise the hands will quickly get tired of holding the tool. After that, the bottle is placed on the pin, the tip of the future fishing line is cut off from the lower edge, and passed through one of the holes in the corner. After that, just pull the end of the strip, and the container will cut itself.

Features of using a bottle cutter from a corner

The resulting fishing line is best rolled onto a reel or rolled into a ball. The knife in such a cutter quickly becomes dull and requires replacement. To adjust a new position, sometimes you have to spoil several bottles. In addition, the tape produced with such a cutter is rarely perfectly flat. Therefore, a bottle cutter from an iron corner is best used to obtain fishing line that will be used on the farm, and not to create decorative elements.

Bottle cutter for perfectly straight tape

Another option for how to make a do-it-yourself bottle cutter is less common. It is made from materials at hand, but the process of creating such a tool takes longer and more laborious. The advantage of such a product is that the ribbon made with it turns out to be perfectly flat and is suitable for making crafts and jewelry.

To make such a cutter, you will need:

• wooden block;
• hacksaw;
• pin;
• sharpened knife blade;
• several screws with washers;
• a piece of PVC pipe with a diameter of 2 cm.

The process of making a bottle cutter with your own hands from a wooden bar:

1. The block is sawn into two pieces, 10 cm and 5 cm in length.
2. The main part of the cutter is a 10 cm long block.
3. The pin must be placed in the block at an inclination of 7 degrees, bending it or drilling the hole obliquely. You need to put a PVC pipe on the pin. This arrangement allows the production of a tape 5-15 mm wide, depending on the presence of a nozzle.
4. Then, on the main block, you need to make several cuts with a slope, using templates for this. This will make it possible to produce tape of different widths on one cut.
5. A knife is attached above the cuts with screws.
6. For a stable position of the bottle, you need to attach ribs from the second part of the bar to a hand-made bottle cutter. They are glued to the main part so that the distance from the center of the pin to the edge of the rib is 45 mm.

Features of the wooden bar bottle cutter

The secret of such a bottle cutter is that the blade is above the cuts, so the bottle does not move during cutting, the tape is homogeneous. The cut is made slightly at an angle, and the position of the blade is adjusted to the desired size of the tape. For example, the cutting height can be 1 cm on one side and 9 mm on the other. The wider the tape, the more the bottle tilts on the machine, because the pin is attached to the bar at an angle. But it is important not to overdo it, otherwise the cut will be strongly bored and the pulling of the tape will be difficult. With a straight pin, the tape simply does not reach the bottom of the cut and breaks off. You can see in the photo a bottle cutter made in this way with your own hands. It may seem difficult to manufacture, but without it it will be impossible to make a flat ribbon from plastic bottles.

Today we will make a simple mobile bottle cutter for cutting tape from plastic bottles. What is it for? This homemade tape has many uses. It can be used in the garden to tie bushes, at home as a clothesline, in the workshop for strong connections. Using it as a heat shrinkage, it is possible to restore almost any tool handle of a simple or complex shape. A big plus of this tape is that when heated it takes the form of the object on which it is wound. It fits snugly to the object and is held on to it.

The strength of the tape is surprising. With its thickness of 1.2 mm, it can easily withstand dynamic loads from a 2 kg dumbbell. In static mode, it must withstand up to 5 kg of load. On an 8-kilogram dumbbell, she cracked.

Now about making a bottle cutter. Used an aluminum corner with a side of 25 cm and a thickness of 2 millimeters. Fasten the corner in a vise, made slots in it for different widths of the tape. Thus, it was obtained, which can give out the tape of different widths.

Next, you need to make two holes for the blade mounts. One of the blade bolts serves as a guide for holding the bottle. The guide is removable, made of a stud from an old engine, a bolt and two m6 nuts. It does not go perpendicular to the corner, it is slightly curved. This shape makes it possible to cut the tape of any width without much effort. Of course, it is easier to make a guide from a rod by cutting a couple of centimeters of threads on it. But there was not a rod or a die at hand.

Now let's see what a plastic bottle cutter is capable of. The thinnest tape he cut to a width of 1.2 millimeters. To get a thin tape, you first need to cut the eggplant perfectly evenly. This is a very important point, because only if you manage to make a very even edge of the eggplant, then you will be able to make a thin ribbon. If you need a wider tape, then you can cut it off somehow.

Simple bottle cutter.

The author of this video decided to make it simple for himself and show how to make it for those who do not want or do not have the opportunity to make a more complex device. Perhaps you will like this method and you will also want to make yourself the same mini-machine for plastic rope.

To do this, we take a pipe of any convenient size, taking into account that part of it is set aside for the working unit, and the second part becomes a handle. You will also need a triple blade from a clerical knife and 2 screws.

First, you need to make a longitudinal cut with a hacksaw about 5 cm. You also need to make a perpendicular cut for the knife. With a one and a half millimeter drill, make 2 holes for the screws. The device is almost ready. To use it, you need to make an incision in the plastic bottle and insert the tape and blade into the incisions. You can start cutting the tape. In this case, it is important from the very beginning to make an even cut at the bottom of the bottle.

This publication contains all the materials of the blogger lawyer Yegorov, in which he tells and shows clearly how to make a bottle cutter for cutting ribbons, rope and fishing line from plastic bottles. There are also additions that will help if not all points have become clear from the main part. In the last part of this article, you will find a link to the drawing of the bottle cutter.

The materials are divided into several parts.

Check out the first version of the rope mining device first. Further, a more perfect, second version of his adaptation. In the third part, other masters explain in detail and in an accessible manner the entire technology of manufacturing a machine for a tape from pvc bottles. As a basis, here too, the approach presented in the video of the lawyer Egorov is used. Who is interested in the drawing, you can find it at the bottom of the page. But we still suggest that you familiarize yourself with all the developments and choose the most optimal design for your requests.

The photo below shows the device that will be discussed in the second video.

This model is not so common, it was the first model to perform well. It differs from the second model in that to cut tapes of different widths, it is required to twist the regulators each time. Its advantage is its ease of manufacture.

This video is about how to create and use a desktop machine for cutting tape from a 1.5 liter bottle or other volume and how to use the shrink properties of such a tape. In the development of this machine, the author used the experience of another blogger, while the author's development was somewhat changed by him. The difference between the machine tool of the lawyer Egorov is that it allows you to cut the tape of different widths. This is achieved by simply repositioning one or more washers higher or lower. This design is also, unlike the original source, stronger and more reliable. This is achieved through the use of other materials. It does not use glue, adhesive tape, and uses a purely bolted connection. There is one more difference - ease of assembly.

To demonstrate the shrink properties of such a tape, a tetrider-based structure was assembled. How is the stiffness of the joints achieved? A pvc tape is wound and heated by a lighter or other heat source. The tape shrinks. When heated, the tapes constrict the object. During the shrinking process, the tape becomes narrower, thicker and stronger.

What do you need to assemble the machine?

A piece of laminate. Large and small washers, 2 nuts, two bolts, a piece of a utility knife. From tools: 2 drills, screwdriver for, pencil, wrench.

The markup will be simple. We connect two washers in one place and mark the holes. The hole must not be fully drilled. We change the drill. We drill through holes. There are two holes. We insert the bolt into the hole. As you can see, it is not drowned. We need to drown him. Do the same with the second bolt. In order to cut a tape 2 times the thickness of the washer, place two washers on each bolt.

Then put a utility knife blade on one of the bolts. Place at least one more washer on each bolt. Orient the blade so that the visible part of its cutting edge is located in the zone formed by the shortest distance from washer to washer. Align washers and tighten nuts. The machine is ready. It can be securely fixed on the table with self-tapping screws or a clamp. The polyethylene used in the bottle is colorless. It can be transparent or painted in any color. The most popular colors are green or brown. First, an unnecessarily thin black tape with a width of 1.5 millimeters will be cut in the frame. This is done in order to demonstrate that such a thin strip will cut just as well as a wide one.

Such tape in a 2-liter bottle is more than 35 meters. 2 5 liter bottles are enough to tie the raft. Joints with such a tape are very strong and tight. After shrinking the tape with the help of a square made of a fire, the knots became one-piece, and the raft itself rallied so that more could not be desired. The connection turned out to be stronger and tighter than wire twisting.

Explaining how to make a bottle machine

Further, the video, which clearly and clearly describes the entire manufacturing technology of the machine, which is not so well viewed in the previous video, but here you can familiarize yourself with the whole process in detail. The author of this craft is Alexander Tkachenko (YouTube).

Aluminum channel with dimensions 20 x 30 x 20 millimeters. 6mm bolts. Hairpin 50 centimeters long by 6 millimeters. Nuts, washers 6 mm. Screwdriver bit set. The blade from a construction knife is 18 millimeters wide. Drill 6 mm. Auxiliary tool, screwdriver, ruler, tape measure, metal saw, marker.
So, there is an aluminum channel. Inside there will be a blade that will be pressed against the channel wall in the finished machine using a wooden block. A drawing of a bottle cutter based on Egorov's bottle cutter can be found at the bottom of the page.

We focus on the location so that it is convenient to hold the channel with your hand and so that you can screw the bottle cutter sideways to a wooden rack and cut the tape from plastic bottles.
We assume that the blade will be located inside the channel, but it is not very convenient to make markings. Therefore, we put the blade on the outside and mark the holes on it with a marker. Next, we mark the place where the cuts should be. 7 cuts in total. We also indicate the upper part of the knife. There is one caveat. When the foreman applied the knife for marking, he did not take into account the thickness of the metal. Therefore, when marking, you need to apply a blade taking into account the thickness of the metal. In this case, it is 1.5-2 millimeters. The foreman corrected the error by re-drilling the holes. The markup is complete.
A pin will be inserted into the marked hole. In the marked places, we cut the slots with a hacksaw for metal. We cut it like this: first, a short slot for a thin plastic tape, then gradually increase its length with each step. That is, first we cut through the closest one, which is closest to the hole from the hairpin. The step is about 2 millimeters. Then we increase the step.
The photo shows how a slotted channel should look like. The length of each of them corresponds to the width of the pet tape.

Next, we drill a hole on the side opposite to the one that has already been made. After that, you can insert the pin by pushing it through both holes.

There are nuances. When you make cuts, be sure to cut clearly on the side from which you are adjusting the width of the tape to the width you want to achieve. On the other hand, on the contrary, you need to make wider cuts in order for the bottle to adhere to the knife as much as possible in this part.
When you twist the hairpin, it is best to bend it ahead of time. On the channel, it remains flat. The blade should fit snugly against the channel.
What is a bottle cutter for? First of all, you can make shrink tape with it. It is great for repairing various tools and devices.

What are the best plastic bottles for this bottle cutter? They should be without relief. If you use a bottle with a relief, then the tape will work, but it will not be of very high quality. Moreover, it is inconvenient to work with such a blank. The cut on the bottle, when you cut the bottom, it should be straight.

If you are not tired of reading, then there is more on this topic.

Powerful bottle cutter with blueprint

Next, watch the video for a powerful PET bottle tape cutter that can be used even on an industrial scale. Its peculiarity is high reliability and performance. The master made a drawing of the cutter, which he made on the basis of the bottle cutter of the lawyer Yegorov. If you do not want to do the whole structure, then use that part of the drawing that reflects the main working part, which coincides with the device that was made by the lawyer Yegorov.

The video shows the details of making a bottle cutter

So spring has come, the need for garters, in your yard or in the country, has greatly increased. On the Internet there are quite a few descriptions of homemade devices for opening plastic bottles onto wonderful heat shrinkable ropes. All these devices have the same principle of operation, but a different type, material and manufacturing method.

Video: Test, the width of the resulting lace is 2 mm.

I also decided to repeat one of the most successful and simple, in my opinion, options, but unfortunately for some reason his work did not suit me, the thread was constantly torn, the width of the cut was floating. I had to modify the design for myself, having received the desired result of the mechanism's operation, and as a result, another option was born for public viewing.

PARAGRAPH 1. List of required materials and tools.
1. Aluminum corner
2. Nail 200 mm., Die M6
3. Blade from a construction knife
4. Nuts, washers
5. Drill, drill d = 6 mm, d = 3 mm
6. Bulgarian
7. File, file, sandpaper.

Point 2. Manufacturing.

Scheme: Principled.

We put the blade on the corner, sharpening it close to the corner, mark the drilling point for the mounting hole.

Mark the cutting line.

We drill a hole d = 6 mm. and saw off the workpiece.

We make markings for saw cuts with a step of 5 mm from the edge of the hole.

We cut it with a saw for metal or immediately with a grinder (disc 1-1.2 mm thick). On one side of the corner, the cuts should correspond to the size of the estimated (desired) width of cutting future threads (ropes), in the photo there are approximate sizes, each one makes for himself. On the other side, the saw is made almost to the full width of the corner, we leave 1-2 mm. jumpers.

We finish the slots with a grinder.

It is very important to process everything with a file and sandpaper so that there is not the slightest catch while pulling the thread.

Round off all the corners.

Chips are well removed by a stiff metal brush.

In the diagram: It is advisable to use a grinder to remove the rounding inside the corner so that the blade rests against the wall, and not against the rounding.

View of the corner to the groove.

View after fillet groove.

Let's make an axle from a two-hundredth nail, its diameter is 6 mm. We cut 15-20 mm. thread M6.

We cut off the edge without removing the die.

Let's fix the damaged thread right away.

IMPORTANT- bend the axis a little, this should set the cutting angle and at the same time the automatic feeding of the bottle blank.

If the thread does not fit into the hole of the knife, then you can sharpen the thread a little.

Or bore a little hole in the knife with a homemade drill with sandpaper.

Everything went well, we install the hairpin with washers in place. We fix the mechanism in a vice.

POINT 2. Check in work.

The result turned out to be unsatisfactory, the thickness of the resulting thread is constantly changing and, as a result, frequent breakage.

I think the reason for this is a slightly incorrect angle of attack of the knife, if you put 0.1-0.2 mm. lining on the back of the blade, then when cutting the thread, the bottle material itself will ask for the knife, and not try to jump off it.

But I did not go the easy way and changed the mechanism for feeding the bottle for cutting.

If everything worked out for you right away, everything cuts perfectly, then congratulations. For those who have problems, read on.

POINT 3. Refinement.
Saw off a corner 45 mm long.

We drill two holes d = 4 mm. We outline the lines of the cut.

Using a grinder, on both sides, cut out the middle.

We process with a file, a file on the edges.

We mark a hole under the hairpin.

We drill D = 6 mm.
