ABSTRACT:
A method of thermally splicing a first zipper to a second zipper, and the thermally formed splice produced by this method, are provided. The first and second zippers each include a male profile and a female profile adapted to interlock with each other. The splice is prepared by thermally fusing an end section of the male profile of the first zipper to an end section of the male profile of the second zipper and thermally fusing an end section of the female profile of the first zipper to an end section of the female profile of the second zipper. Alternatively, the splice can be prepared by thermally fusing the end sections of two closed zippers. The male profile of each zipper includes a male locking member, and the female profile of each zipper includes a female locking member. To provide substantial continuity between the male locking members of the first and second zippers and between the female locking members of the first and second zippers, a notch is formed in the end section of the male profile of the first zipper and the end section of the female profile of one of the first and second zippers prior to thermally fusing the end sections of the two zippers.
