<p>A slider for a large sized slide fastener which includes a slider body of synthetic resin material and an integrally formed metal core member embedded in the slider body. The slider body includes opposed top and bottom wings and a neck portion connecting the top and bottom wings at one end thereof. The core member includes portions each corresponding to the top wing, the bottom wing and the neck portion of the slider body and extends substantially uniformly throughout the entire area of the slider body. The core member further includes at least in the portions corresponding to the top and bottom wings a plurality of apertures or recesses which receive a portion of the synethetic resin material of the slider body upon molding thereof. The invention provides an advance, particularly in the field of large sized slide fasteners, due to an improved integrity of the core and the plastic.</p> |
