ABSTRACT:
A coupled slide fastener strip is gripped by at least one clamping member adjacent where a cut is to be made in it on one side at the beginning of a leading coupled slide fastener and on the other side at the end of a trailing coupled slide fastener and then the leading coupled slide fastener is separated from the slide fastener strip held by the clamping members by cutting. Then subsequently, the end piece is mounted at the end position the trailing coupling slide fastener with a clamping member and substantially simultaneously, the leading coupled slide fastener separated from the coupled slide fastener strip is moved with that or another clamping member from a cutting position into a slider drawing position. In the slider drawing position the slider is drawn in the opening direction of the coupled slide fastener and optionally the beginning piece is mounted. After that, the slider is drawn in the closing direction. Finally, the separated trailing coupled slide fastener is released for stacking and the clamping members are repositioned in the cutting position.
