Each of coupling elements mounted on a slide fastener stringer tape has a coupling head and two legs extending from the coupling head and mounted astride of a longitudinal beaded edge of the stringer tape, the legs being integrally interconnected by a connector extending through the stringer tape. The coupling elements are removed from the stringer tape by gripping the stringer tape between a pair of grippers with the coupling elements supported on the grippers, thrusting cutting edges into the coupling head of each coupling element toward the longitudinal beaded edge to break the coupling head, and driving wedge-shaped spreaders into each coupling element through the broken coupling head thereof to spread each coupling element until the connector is forcibly broken, for thereby breaking each coupling element into two pieces off the stringer tape. |
