    摘要： A molded surface fastener is manufactured by supplying molten resin to the circumferential surface of a die wheel rotating in one way to mold a substrate sheet blank and a multiplicity of substantially straight and inclined engaging element blanks in an integral form, and then pressing distal ends of the engaging element blanks by a heat-molding roller in rotation at the same speed to incline the engaging element blanks further toward the substrate sheet blank and also to melt the distal ends to shape each said distal end into an engaging head projecting in a direction opposite to the direction of inclination of the respective engaging element blank. Each of the resulting engaging elements is composed of a stem rising from the substrate sheet surface with inclination by a predetermined angle (.theta.1), and an engaging head projecting from an upper end of the stem in a direction opposite to the direction of inclination of the stem, an extension line of the engaging head crossing the substrate sheet surface at a predetermined acute angle (.theta.2).

    摘要： A surface fastener molded of synthetic resin, comprises a substrate sheet, and a multiplicity of hook elements molded on at least one surface of the substrate sheet, each hook element having a hook body having a stem and a curved portion. Each of the hook elements has first and second reinforcing ribs projecting from opposite side surfaces of the hook body. The first reinforcing rib is greater in height than the second reinforcing rib. In the presence of the first and second reinforcing ribs different in height, compression stresses developed in the hook body are dispersed at two or more points when a companion engaging element is removed off the hook element.

    摘要： In a molded surface fastener, a hook has vertical multi-step reinforcing ribs on opposite side surfaces of a stem, and it is therefore possible to make the hook-shape engaging portion adequately soft and to increase the rate of engagement with loops. Further, since each reinforcing rib extends to the curve of the hook-shape engaging portion, it is possible to secure a predetermined degree of engaging force, despite the thin and soft hook-shape engaging portion, unlike the simple reinforcing ribs of the conventional art.

    摘要翻译： 在模制的表面紧固件中，钩在杆的相对侧表面上具有垂直的多步加强肋，因此可以使钩形接合部足够柔软并增加与环的接合速率。 此外，由于每个加强肋都延伸到钩形接合部分的曲线，所以与常规技术的简单的加强肋不同，尽管具有薄且软的钩状接合部分，但是可以确保预定程度的接合力 。

    摘要： A high-quality molded surface fastener is manufactured by extruding molten thermoplastic resin, in a predetermined width, from an extrusion nozzle to a circumferential surface of a die wheel having a multiplicity of engaging-element-forming cavities, driving the die wheel for rotation, and molding a multiplicity of engaging elements integrally with a plate-like substrate sheet. At the same time, pseudo elements are molded integrally with the substrate sheet along opposite side edges, using pseudo-element-forming cavities in opposite side circumferential surfaces of the die wheel simultaneously. With the pseudo elements, the molded surface fastener is peeled off the die wheel under a uniform peeling force through the entire width of the substrate sheet. Thus the high-quality surface fastener can be obtained.
