Abstract
A mold-in fastening member which is composed of a strip of substrate, engaging elements formed on one surface of the substrate, and an elastomer layer completely surrounding the engaging elements, the substrate having slits or notches which extend from a widthwise central portion of the substrate to a widthwise end portion of the substrate. The mold-in fastening member bends in conformity with a two- or three-dimensionally complicated shape of a molded article. The mold-in fastening member prevents the surface having the engaging elements from being covered with a foamable liquid molding resin during a mold-in process, thereby preventing the engaging elements from losing the engaging function.

A mold-in fastening member which comprises a strip of substrate, engaging elements formed on one surface of the substrate, and an elastomer layer completely surrounding the engaging elements, the substrate having slits or notches which extend from a widthwise central portion of the substrate to a widthwise end portion of the substrate.
A method of producing a molded article of foamed resin having a fastening member using a mold-in fastening member which comprises a strip of substrate, engaging elements formed on one surface of the substrate, and an elastomer layer completely surrounding the engaging elements, the substrate having slits or notches which extend from a widthwise central portion of the substrate to a widthwise end portion of the substrate, the method comprising:
- fitting the mold-in fastening member into a recess formed in a mold while allowing the elastomer layer to face a bottom of the mold;
- injecting a foamable liquid resin into the mold;
- hardening the foamable resin to obtain a molded article having the fastening member;
- releasing the molded article having the fastening member from the mold;
- and
- removing the elastomer layer.
