Description

TECHNICAL FIELD [0001] The present invention relates to a method of manufacturing a strip-

The present invention relates to a method of manufacturing a strip for cable treads, and more particularly, to a method for manufacturing a strip for cable treads which can stably carry out a mass repetitive production operation of strip strips for cable treads.

Generally, a cable tie is used to fix a cable or a plurality of tubular members to a fixed position or bundle at once. The most widely used cable tie is a ball type cable tie, The most important thing is the strip body used to tie the cables. Such strips are mainly strips of a predetermined length in the form of strips made of a metal such as stainless steel. Such a strip body should be subjected to, for example, a cutting operation of cutting to a length of 30 cm and a bending operation in which one end of the cut strip body is fixedly bent to the ball head to form a bent end. Since the cutting operation and the bending operation are both performed manually or each machine must be performed separately, a manpower is indispensably required and continuous operation becomes impossible, which limits the amount of the strip body to be produced. I was desperately demanding. In particular, a more stable manufacturing method is required due to the characteristics of the strip body in which mass repetitive production is essential.
