Abstract
Apparatus for producing gaps in zipper chain is especially adapted for chain having plastic elements of U-shape joined by imbedded connector threads and stitched to tape. Apparatus includes slitting means which slice into and demolish fastener elements in the gap as the zipper is drawn along, and lancer elements which are periodically activated to cut the connecting threads at the beginning and end of the gap. Stitches and tape in gap are left intact.
