Abstract:
1. A mold-in fastening member comprising: a substrate having engaging elements on a top surface thereof; a foamed synthetic resin layer bonded to a rear surface of the substrate, the foamed synthetic resin layer having lateral overhanging marginal portions extending outwardly beyond at least both lateral edges of the substrate, and having a thickness of 1 to 10 mm and an initial compressive modulus of 0.02 to 1.0 MPa; and a ferrite-containing layer positioned on said top surface of the substrate opposite said rear surface, substantially all of said ferrite containing layer being positioned between said engaging elements, the foamed synthetic resin layer having longitudinal overhanging marginal portions extending outwardly beyond both longitudinal edges of the mold-in fastening member, wherein the foamed synthetic resin layer comprises a polyurethane resin, and each of the lateral overhanging marginal portions and the longitudinal overhanging marginal portions has a width substantially the same as a width of each of corresponding lateral and longitudinal shoulders of a recess formed in a mold in which the substrate is placed, the mold having a magnet embedded therein to attract said ferrite-containing layer.
