Abstract: Connected fastening members and method for mold-in articles. The connected fastening members include a plurality of mold-in fastening members each having a substrate and a predetermined number of engaging elements formed on a first or front surface of the substrate. The mold-in fastening members are connected with each other by a connecting member that is disposed on a second or the back surface thereof. Using the connected fastening members, a plurality of the fastening members can be easily fit to a recessed portion of a mold in a single operation, resulting in improved working efficiency.

Abstract: The mold-in fastening member, that can be molded into a resin article, of the present invention comprises (a) a substrate having a front surface and a back surface; (b) a plurality of engaging elements provided on the front surface; (c) a plurality of anchoring elements provided on the back surface, the anchoring elements being embedded into the resin article to fix the mold-in fastening member thereto; (d) a ferrite-containing layer formed on the front surface; (e) marginal portions continuously extending along respective lengthwise edges of the substrate; and (f) grooves formed on the substrate, which extend along the respective marginal portions to render the marginal portions easily bending relative to the substrate. The fastening member is easily placed in position on shoulders of a recess formed on a mold and protects the engaging elements from being buried or contaminated by a foaming resin because the ingress of the foaming resin into the recess is effectively prevented due to the close contact of the marginal portions with the shoulders. The fastening member of the present invention is small in size and improve the productivity, safety and working efficiency of the production of molded resin articles having mold-in fastening members.

Abstract: The mold-in fastening member comprises a substrate having engaging elements on a top surface thereof and a foamed synthetic resin layer bonded to a rear surface of the substrate. The foamed synthetic resin layer has overhanging marginal portions or sealing portions extending outwardly beyond at least both lateral edges of the substrate. The foamed synthetic resin layer has a thickness of 1 to 10 mm and an initial compressive modulus of 0.02 to 1.0 MPa. The mold-in fastening member surely prevents a molding resin from entering through gaps between the mold-in fastening member and a recess formed in a mold.
