<p>A slide fastener slider is disclosed, which slider comprises an upper wing and a lower wing constituting a slider body and connected together at one end by a neck or wedge. Each of the wings has a pair of inwardly directed flanges. One of the wings is provided with diverging shoulders, while the other is provided with reduced shoulders, resulting in an asymmetric wing structure wherein there is formed an open area on each side of the wedge. The open areas serve reduce the tendency of stringer tapes to become creased or wrinkled as they arrive at the entrance end of the slider. The invention thus provides the advance of smoother movement of the slider particularly in the art of heavy slide fasteners such as the ones used in vehicle hoods.</p> |
