Abstract
A mold in fastener product includes a flexible substrate, such as a resin film or textile sheet, and a resin layer covering only part of one side of the flexible substrate and leaving a region of the one side of the flexible substrate exposed, the resin layer carrying multiple touch fastener elements each having a resin stem extending integrally from the layer away from the flexible substrate to an engageable head. A flexible ferromagnetic strip is bonded to the flexible substrate and at least partially bounds a bounded portion of the flexible substrate containing at least some of the touch fastener elements and at least a part of the exposed region. The product is preferably wide, such as to cover a wide concave region of a foam seat cushion.
Claims21
A method of making mold in touch fastener products, the method comprising:
- molding a resin layer on a side of a flexible substrate, leaving a region of the side of the flexible substrate exposed;
- providing the resin layer with multiple touch fastener elements each having a resin stem extending integrally from the layer away from the flexible substrate to an engageable head;
- and
- providing a flexible ferromagnetic strip bonded to the flexible substrate and at least partially bounding portions of the flexible substrate containing at least some of the touch fastener elements and at least a part of the exposed region.
A method of forming a foam product having an embedded fastener product, the method comprising:
- positioning a fastener product against an interior surface of a mold cavity, the fastener product comprising
- a flexible substrate;
- a resin layer covering only part of one side of the flexible substrate and leaving a region of the one side of the flexible substrate exposed, the resin layer carrying multiple touch fastener elements each having a resin stem extending integrally from the layer away from the flexible substrate to an engageable head;
- and
- a flexible ferromagnetic strip bonded to the flexible substrate and at least partially bounding a bounded portion of the flexible substrate containing at least some of the touch fastener elements and at least a part of the exposed region;
- closing the cavity;
- introducing foaming resin to the cavity to cause the foaming resin to flow and expand to fill a volume within the cavity and engage a side of the fastener product opposite the resin layer;
- and
- curing the expanded foaming resin to form a molded foam product with the fastener product secured to cover a portion of a surface of the foam product.
