ABSTRACT:
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.
