Abstract
A device for positioning a pair of longitudinally advancing elongate slide fastener stringers comprises a pair of positioning jaws movable relatively to one another in a direction substantially perpendicular to the plane of each slide fastener stringer to define therebetween a guide channel for the passage of the slide fastener stringer. At least one of the positioning jaws includes a step for engaging the leading coupling element of each coupling element row mounted on one longitudinal edge of a tape of each respective slide fastener stringer, for thereby stopping the slide fastener stringer. The positioning device having the positioning jaws is capable of accurately positioning the slide fastner stringers even when the slide fastener stringer is laterally undulated or locally swelled during advancing movement thereof.
