Abstract: A plastic hockey-stick is made in three layers, around a core. The blade-core is retained but the handle-core may either be retained or withdrawn during manufacture. The inner layer is of hoop-laid strands, which gives rigidity to the cross-sectional shape of the handle, enabling the handle to be hollow. The middle layer is of length-laid strands, for good bending strength. The outer layer is of e.g., twisted strand woven cloth, for surface toughness. The enwrapped core is impregnated with resin, and compressed in a mould during curing. The resulting stick combines lightness, strength, resilience, non-dangerous failure mode, and economy of manufacture.

Abstract: A method of forming a double timing belt wherein a belt preform is firstly formed with teeth on one face thereof. The opposite face of the belt in which the tensile cord is embedded is provided with oppositely projecting teeth in accurate alignment with the teeth of the preform by a successive molding of pluralities of such teeth to the opposite face, with the preform entrained about a pair of adjustably spaced toothed pulleys. Accurate uniform pitch line difference is maintained by providing shims between the mold and belt support during the molding of the second set of teeth to the preform. The mold and support are retained in accurate alignment by cooperating dowels and recesses on the support and mold members. Cooling devices are provided at opposite ends of the mold for preventing full vulcanization of the tooth rubber thereat.

Abstract: Wire arrays (11) having a continuous wire (12) which is formed into a predetermined pattern and adhered to a backing material or substrate (13) are fabricated by applying adhesive material (16a, 16b) along opposite edge portions (17, 18) of the substrate, positioning a row of winding spools (21) along each of the edge portions and repeatedly extending the wire between and around successive spools at the opposite edge portions. The wound wire is then traveled along each spool toward the substrate and into contact with the adhesive. The spools are then removed and a coating of hardenable material (54) is applied to secure the wound wire to the substrate. Tension in the wire is relieved prior to contact of the wire with the adhesive and a small amount of slack is introduced into the wire before the final coating step. Mechanism (32) is provided for lifting the spools away from the substrate without disturbing the wound wire.

Abstract: To produce a vessel prosthesis, a hose (12) is wrapped with a reinforcing thread (13) to avoid bending and clogging of the vessel prosthesis. The reinforcing thread (13) is wound substantially tensionless on the soft hose (12) thus prohibiting wavy deformations inside the hose. To exclude prior to the solidification of the adhesive connection a displacement of the reinforcing thread (13) being bonded to the hose, a band-shaped spacer (14) is wound up together with the reinforcing thread (13) and removed subsequently.
