Abstract: A hook fastener portion is disclosed for use in a hook and loop fastener that has a woven backing with portions of pile monofilaments projecting from its front surface providing hooks adapted for making releasable engagement with loops of the fastener. In another embodiment, a hook fastener-portion is disclosed for interengagement with an opposed, like hook fastener portion. A layer of thermoplastic material along a rear surface of the backing and the mechanical engagement of the portions of the pile monofilaments woven into the backing anchor the monofilaments in the backing, and that layer of thermoplastic material can be a hot melt adhesive used to adhere the hook fastener portion to a substrate.

Abstract: A method for making a sheet material adapted to be cut into smaller ravel resistant pieces to form portions of a fastener by intersecting (e.g., weaving or knitting) portions of base yarns to form a backing, with at least some of the base yarns being bonded yarns including a first portion formed of a polymeric structural material and a second portion formed of a thermoplastic binding material having a significantly lower melting temperature than the softening temperature of the structural material. Portions of pile yarns are entwined in the backing with the entwined portions of the pile yarns contacting at least one of the bonding yarns, while other portions of the pile yarn project from the backing to form loops or hooks. The backing is heated to soften the binding material so that it flows and, upon cooling, adheres to adjacent portions of the yarns, thereby anchoring the pile yarns in the backing.

Abstract: A work piece is mortised to receive an insert, and drilled for fastenings securing the insert in position, in a single cycle of operation facilitated by mounting the drill in an axial hole in the routing cutter. The drill is guided by the radially inner surfaces of the specially hard cutter inserts. A mechanism advances and retracts the drill with respect to the cutter, with the extension of the drill beyond the cutter taking place only when the cutter is not moving laterally in forming the mortise. The mortised depth is accurately controlled by an adjustable stop traversed by the drill, and forming an abutment limiting the insertion of the router bit into the holding collet. In addition to the plunge and horizontal movements involved in the formation of the mortise, a vertical movement to form mortise side-openings is provided by pivoting downward the frame carrying the entire movement system.
