ABSTRACT:
A slide fastener slider has an arch-shaped lug projecting from the front end of an upper wing over the top surface of the upper wing toward the rear end thereof and terminating in a bent free end directed toward the upper wing's top surface and spaced apart therefrom by a gap s. A pull tab is threaded on the lug and thereby connected to a slider body. The slider also has a ridge projecting from the rear end of the upper wing and aligned with the arch-shaped lug longitudinally of the slider body, the ridge having a width not less than the width of the free end of the lug and having a height not less than the gap s. The ridge serves to prevent the slider from being improperly mounted on a guide, as it is fed from a hopper to the next station by a parts feeder, thereby enabling smooth feeding of the successive sliders.
