When packing straps are manufactured, there are usually interface problems. There are many ways to manufacture the interfaces, as follows:
1. Hot-melt lap type; it adopts heating method such as electric heat welding, mechanical high-frequency oscillation welding and ultrasonic welding, which is the surface layer of plastic belt is heated and melted, and the melting surfaces of the two belt ends are overlapped. This method is suitable for gathering. The propylene plastic belt has a strength of only 50% of the base metal, and the adhesive connection is not applicable.
2, metal buckle type: is to use the tensioner ratchet wheel one-way work, then put a metal buckle at the joint, and then use the clamp to wrap the iron buckle around the two layers of tape, bite the tape does not make it loose.
3. Ligation type: This type of joint is made of soft plastic rope, hemp rope, etc., and the joint is made into a slip knot. This type of joint is both aesthetically pleasing and easy to unravel.
