Technology for making brooms from plastic bottles
To make a broom, you need to cut prepared 1.5-2 liter bottles into a 5 mm wide ribbon.
As the cutting progresses, the tape is wound around the template. You can use chipboard or boards measuring 250x300 mm as it. A frame made of profile or slats is also suitable. The tape is wound tautly. Each new ribbon is connected to the previous one with an ordinary knot. When winding, it is important to distribute the skeins evenly, without placing thick layers in one place.
To prevent the tied tape from unwinding, its end must be fixed. To do this, you can screw a self-tapping screw into the template and tie it to it.
Then you need to heat shrink the tape. When heated, it will shrink, curl into a tube and become tougher. You can use a hairdryer on minimum heat.It is important to act carefully so that when heating the lower layers you do not burn the upper strips. It is best to do heat shrinking with boiling water. You can pour several liters of boiling water over everything from above or by immersing the structure in it. Water will cover each turn evenly, but it will ruin the template if it is made of chipboard.
After shrinking, you need to cut the tapes along one of the ends of the template. The double twigs are hung on a piece of tape, folded into a ring and tied. Rods on which heat shrinkage has not occurred should be removed.
The bundle is leveled and tied with tape slightly below the crease.
A 1 liter bottle with a cut neck and bottom is put on it. Then the bunch is stuffed onto the stalk.
Next, the workpiece is clamped in an improvised vice made of slats twisted with self-tapping screws. The bun is straightened and the top bottle is set with a hairdryer. After this, the broom is secured to the handle with a self-tapping screw. The uncrimped bottle skirt is cut off.
The pile is cut and becomes smooth without bends.
A broom made using this method has medium hardness. It is convenient to use for cleaning smooth surfaces. If you need to sweep asphalt with deep potholes, then it is better to use an 8-10 mm tape during production. When heat-shrinking, it curls into dense tubes, so the broom will be more rigid.
