ABSTRACT:
Gapping of slide fastener tapes is performed by cutting longitudinal connecting and supporting members carrying fastening elements on both sides of each element to be removed along perpendicular cutting lines. The fastening elements are then removed by pulling the fastening elements and the severed ends of the connecting and supporting members from between loops of weft threads which secure the connecting and supporting members in the inner edges of the tapes.
