ABSTRACT:
A slider for a slide fastener comprises a slider body including a pair of upper and lower wings defining therebetween a Y-shaped guide channel, the lower wing having on its interior surface a ridge extending longitudinally of the guide channel for being locatable between a pair of stringer tapes of the slide fastener to slidably engage fastener elements of the slide fastener. The lower wing also has in the interior surface a pair of furrows disposed one on each side of the ridge and extending parallel thereto for allowing fastener-element-supporting edge portions of the tapes to be displaced into the furrows respectively. The furrows thus reduce frictional resistance between the stringers and the interior surfaces of the slider body. With such slider it is possible to correct a longitudinal divergence in interengagement between the opposed stringers without breakage or other damage to fastener-element-holding threads.
