ABSTRACT:
A method of attaching bottom stops of a generally H-shaped cross section to a slide fastener chain. One of successive spaced pairs of opposed blank tape portions of the fastener chain is spread apart. A bottom stop, which has two pairs of gripping legs, is placed between the spread pair of opposed blank tape portions. The spread pair of opposed blank tape portions is then released and thereby allowed to come toward each other until a pair of opposed blank beaded tape edges are threaded one through a space between each pair of the gripping legs of the bottom stop. Then, the blank beaded tape edges are compressed against the bottom stop on opposite sides. Finally, the gripping legs of each pair are clinched about the compressed beaded edge of a respective one of the stringer tapes. An apparatus for carrying this method is also disclosed.
