摘要： A molded surface fastener comprises: a substrate sheet; and a multiplicity of engaging elements standing on one surface of the substrate sheet, each of the engaging elements being composed of a stem rising from the one surface of the substrate sheet, and an engaging head projecting from an upper end of the stem for detachably engaging a companion loop. After a surface fastener is manufactured on a die wheel by continuous injection molding as a primary-intermediate surface fastener, a heating and pressing roller disposed downstream of the die wheel presses the engaging head, while heating, to bend the engaging head from the stem and, at the same time, to form a pair of protuberances projecting in opposite directions from opposite side edges of the top of the engaging head perpendicularly with respect to a direction lengthwise of the engaging head.

摘要： In a molded surface fastener, a hook structure has on at least one surface of a stem an upright reinforcing rib extending from the base of the stem to part of a hook-shape engaging portion. The reinforcing rib projects upwardly with respect to the rear surface of the hook-shape engaging portion and terminates in an apex whose height is smaller than the height of the apex of the hook-shape engaging portion and greater than the height of the line tangential to the hook-shape engaging portion at the tip and substantially parallel to the upper surface of the substrate sheet.

摘要： In a hook structure for a molded surface fastener, in an arbitrary cross section of each of a stem and a hook-shape engaging portion of a hook, the cross-sectional area is divided into front and rear side cross-sectional areas with respect to the center line of the hook, and the front side cross-sectional area is defined to be larger than the rear side cross-sectional area. Therefore, the neutral plane of the hook is shifted toward the front side of the stem and the inner side of the hook-shape engaging portion to a further extent than conventional to reduce possible tensile stresses in the front part of the stem and the inner part of the hook-shape engaging portion so that, as compared to the conventional hook made of the same resin quantity and having a substantially similar shape, the strength of the hook is increased sharply and, necessarily, both the front part of the stem and the inner part of the hook-shape engaging portion is increased in rigidity as compared to the other part and hence is difficult to deform, thus causing an increased strength as well as an increased engaging strength with a loop of a companion surface fastener.
