The material from which PET bottles are made shrinks when heated. Thanks to this, the tape from it can be used instead of a rope or linen cord for a strong connection. various materials makes it possible to produce various . It is almost impossible to cut ribbons with scissors - I made a special device for this.
You will need: a few large washers 2 solid thread bolts, nuts and washers a box cutter blade with a hole a piece of plywood (board, laminate).
On the plywood platform we lay 2 large washers pressed against each other (photo 1), mark their centers. We drill holes in them according to the diameter of the bolts. Then with reverse side platforms make a recess in the shape of the head so that they “drown” and the bolts do not rotate around their axis (photo 2). To cut a tape of a certain width on the leg of each bolt protruding from the back side, we put so many large washers so that their total thickness is that width. For example, to cut a 5 mm tape, you will need 3 washers with a thickness of 1.58 mm.
We put the knife blade on top and put at least one more large washer on it (photo 3). Align them and tighten the bolts with nuts. The machine is ready. We fix the platform on the table with screws or a clamp. remove the bottom, cut the strip and insert it under the knife. With one hand we hold the bottle and press on the cork, with the other we pull out the cut tape.
There are many devices on the Internet to cut plastic bands and ropes from bottles or even fishing line. Among them are many complex devices and simple ones. But this cutter is distinguished, in its own way, by ingenious simplicity and grace. For him, well, you need to grind no details, everything is at home or you can buy it very cheaply. The main thing is that you can make it with your own hands in just minutes. With it, you can adjust the width of the tape and make it different sizes.
Just take a look at what this Chinese store has for the garden.
What tools and parts are needed to make this simple cutter?
This is the blade that will perform the action. A clerical knife or, as in this case, from a pencil sharpener. Need washers and 2 screws. You only need a screwdriver.
Progress
We take out the blade from the sharpener with a screwdriver. And now we need to decide what width we will cut the tape from the PET bottle. The combination of washers adjusts the height and width of the rope.
For the product you will need a table into which it is not a pity to drive a couple of self-tapping screws. Although, you can take the board under the machine, and fasten it to the table with clamps.
When a place is found cutting machine, at a distance from each other, we screw in two self-tapping screws with washers. We set the blade to the desired height and clamp it with self-tapping screws.
Now we are preparing plastic bottle rope cutter. Carefully separate the bottom with a clerical knife. The cut must be even. We fill the workpiece in the cutter.
We process a poltorashka with our own hands and a simple machine. To make the thread even, press a little from above. We pull the finished tape from the machine.

A frequently asked question is: How to cut a bottle evenly. I propose to use simple cutter for glass bottles. This device will allow you to cut a glass bottle strictly perpendicular to its axis. With this cutter, you can make a glass from a glass bottle, a ceiling lamp for a homemade chandelier, or cut glass rings from it for your crafts. The tool is easy to make and use.
For work we need: board 14x25 cm (I used a small cutting board, because it was ideal for this purpose), 4 furniture wheels with a diameter of not more than 4 cm (preferably rubber), a piece of PVC cable duct 25 cm long, 2 cm wide with a removable cover. You will also need wooden blocks: 25x4x2 cm, 11x4x2 cm, 25x1x2 cm.
We proceed to the manufacture of the cutting mechanism.
We cut off two bars 3 cm long from a bar 25x1x2 cm. In them, at a distance of about 7 mm from the edge, we drill through longitudinal holes.
On the lever we make a groove for the glass cutter, drill a hole for the screw. A screw with a nut was used to fasten the glass cutter to the lever, because. in the original version, a screw was used, but it did not hold the glass cutter well.
We collect the base of the cutter for glass bottles.
We glue the side beam for the sliding carriage and the stop for the bottle to the base board. We fasten the furniture wheels, the distance between them is 12 cm for not big bottles up to 0.75 liters and we provide holes for screwing wheels at a distance of 17 cm for large bottles from 1 liter and above. We fasten the base of the cable channel to the side beam, it will serve as a rail (guide) for sliding the cutting tool.
So that in the process of cutting the bottle, the cutter does not slide on the working surface of the table from the bottom of the base, we glue the rubber legs.
We cut a glass bottle.
We put the desired bottle, having previously washed the label, on the wheels, press the bottom against the stop, Install the glass cutter in Right place, we press the cutting part against the glass and evenly rotate the bottle along the axis by 360 degrees. The beginning of the cut must coincide with its end, i.e. circle must be closed. We do the cut once, if you do it again, the bottle may crack unevenly.
Then we take a container with hot water(boiling water) and pour it over the place of the cut, then quickly lower the bottle into ice or very cold water. The characteristic crack of broken glass should be heard and the bottle should split exactly along the cut. If this does not happen, you will have to repeat water treatment(from hot to cold).
The separated part is processed flat surface sandpaper medium to fine grit to eliminate sharp edges.
Received a small coffee cup. All tests were successful.
