Embodiment Construction

[0115] In one aspect, the invention features a touch fastener 100 for use as a molded insert. refer to figure 1 , touch fastener 100 includes a sheet-form base 10 having an upper surface 12 and a lower surface 14 . Fastener elements 16 extend from lower surface 14 of sheet-form base 10 in array 20 . The wire 18 is bonded to the upper surface 12 of the sheet-form base 10 by means of an adhesive 22 . A trim 24 extends laterally from the sheet-form base 10 beyond either side of the array 20 . The lower surface 26 of the trim 24 is a smooth planar surface capable of engaging a planar mold surface 28 in face-to-face contact.

[0116] In some examples, such as figure 1 As shown in , magnets 30 may be positioned in mold 32 to position touch fastener 100 in grooved portion 34 of planar mold surface 28 . With the fastener thus positioned, a foamable liquid resin is poured into the molding cavity 27 . An exothermic reaction occurs, causing the liquid resin to foam upwards to fill ...

Abstract

Touch fasteners (52, 100, 200, 300, 400, 500, 500a, 600, 800, 900) for use as mold inserts in molding seat foam buns (700) include selvedges (24, 24a, 24b) that deflect under pressure to engage a mold surface (28, 28a) in face-to-face contact. Another touch fastener (52, 100, 200, 300, 400, 500, 500a, 600, 800, 900) includes a base (10, 10a, 10b) with an exposed thermally activatable resin (40, 40a) surface that has a softening point low enough to be activated by the exothermic foaming reaction to adhere the fastener (52, 100, 200, 300, 400, 500, 500a, 600, 800, 900) in the foam bun (700).

Description

technical field [0001] The present invention relates to a touch fastener product, and more particularly to the use of the touch fastener product as a molded insert in, for example, a molded seat foam bun. Background technique [0002] Seats for cars and light trucks have been formed by molding a foam bun that will serve as the seat cushion, and then attaching a pre-sewn fabric cover to the foam bun. Typically, the fabric cover is attached to the fabric cover by insert molding a touch fastener product to the outer surface of the foam bun and attaching a mating touch fastener product to the inner surface of the fabric cover. Styrofoam blocks. Typically, the fastener product is attached to the fabric cover along the seams that sew the cover together and is held in place by the seam stitches. The touch fastener product allows the seat manufacturer to quickly and semi-permanently attach the fabric cover by pulling the fabric cover over the foam bun and pressing the opposing tou...
