Molded surface fastener and molded surface fastener manufacturing method

A method for manufacturing a molded surface fastener in which a plurality of surface fastener members in which a plurality of hook-shaped engaging elements stand on a first surface of a substrate portion are connected in a length direction by a flexible connecting portions, and which can be integrated to a surface of a cushion body in a bent state in a width direction when the cushion body is foamed and molded, wherein the method includes:

• molding the molded surface fastener as a primary product using a die wheel in which a cavity space is formed on a periphery, in which the substrate portion has engaging regions on which the plurality of the engaging elements stand on the substrate portion and space regions having a flat surface on which the engaging elements are excluded on the substrate portion alternately in the length direction, the engaging region has a pair of left and right resin intrusion barrier portions standing along the length direction at left and right side edge portions of the substrate portion and main lateral wall portions standing along the width direction continuously between the left and right resin intrusion barrier portions at both end edge portions in the length direction of the engaging region so as to compart from the space region, the space region has a pair of left and right vertical wall portions standing along the length direction at the left and right side edge portions of the substrate portion and a convex rib portion projecting integrally from the substrate portion along the length direction at a center portion in the width direction of the substrate portion,
• peeling off the molded surface fastener as the primary product from the die wheel,
• detecting a position of the molded surface fastener by inserting a positioning member to the space region in the molded surface fastener as the primary product and
• performing a cutting processing to the molded surface fastener whose position is detected to cut off the space region so that at least the convex rib portion is remained.
