Method for forming slide fasteners
摘要:
A method of forming a slide fastener having terminal fastener elements reduced in size relative to the remaining fastener elements includes supporting a slide fastener chain to expose the terminal fastener elements, reducing the size of the terminal fastener elements, and fusing a mass of fusible material onto each slide fastener tape to form stop members.
