[0002] Zippers are broadly categorized into closed zippers and open zippers. Closed zippers are further divided into single-closed, double-closed, and X-type types; open zippers are divided into double-open, single-open, and multi-open types. To produce a variety of zippers, zipper equipment has gradually evolved from semi-automatic to fully automatic. The primary condition for the stable operation of both fully automatic and semi-automatic equipment is the consistency of the products being processed. Zipper production is an intermittent production line composed of various devices; the stability of the equipment determines the stability of the zippers produced. Over the years, despite equipment upgrades, one factor hindering stable production has remained unresolved: the zipper belt, a crucial component of the zipper.
