In general, a zipper includes a plurality of scoops (SCOOPs), that is, elements (E), etched and assembled on a tape (T) made of woven paper as shown in FIG. The two lines of the tape T assembled with a low-thickness tape are joined to each other by the sliders S, and the side edges of the tapes are joined to each other or the elements joined by the sliders S. The tape (T) is separated by disassembling (E).

In the process of producing such a zipper, first, weave the tape (T) made of a fabric paper into which the element is implanted as described above, and insert and assemble the element (E) on the tape (T). Depending on the material, that is, the element (E) may be a conventional metal material (Metal Zipper) and a case made of a synthetic resin (Mold Zipper).

The process of inserting the element (E) into the tape (T) is to automatically insert and assemble the element into the tape by a chain machine in the case of a metal zipper, and to the element injection molding attaching machine in the case of a mold zipper. To form an element on the tape.
