摘要

PURPOSE: A slide fastener, a method for manufacturing a slide fastener, and a device for forming a puckering hole are provided to prevent a puckering phenomenon. CONSTITUTION: A method for manufacturing a slide fastener is as follows. Puckering prevention holes or puckering prevention cutting lines are formed at a constant interval in the edge of each fastener tape while supplying film paper to the bottom plane of each fastener tape(2) engaged with an element(5).
