Publication number: 20050183248Abstract: A fastener element with a sheet-form base and an array of wedge-shaped engageable elements molded integrally with a surface of the sheet-form base. The wedge-shaped elements each have a steep side and a gradually rising side, and are arranged with their steep sides all directed in a common sense, such that the array can engage a similar array of oppositely-directed wedge-shaped elements to resist shear motion. The distal edges of the wedges are curved in top view.Type: ApplicationFiled: February 24, 2004Publication date: August 25, 2005Inventors: Christopher Gallant, William Clune

Publication number: 20050151293Abstract: Fastener products having a multiplicity of fastener elements extending from a strip-form base, the base including first and second attachment members for attachment of a substrate therebetween, are formed by continuously introducing molten resin to a gap defined adjacent a peripheral surface of a rotating mold roll. The resin forms part of the strip-form base of the product at the peripheral mold roll surface and fills an array of fixed cavities defined in the rotating mold roll to form portions of the fastener elements as projections extending from a first side of the sheet-form base. While the resin is on the mold roll, a sheet material is introduced.Type: ApplicationFiled: December 6, 2004Publication date: July 14, 2005Inventor: William Clune

Patent number: 6656403Abstract: A composite touch fastener has an elongated, sheet-form resin substrate, a fibrous loop strip partially encapsulated in, or otherwise permanently attached to, resin of the substrate, and an array of loop-engageable fastener elements integrally molded with resin of the substrate. The loop strip forms a discrete band of hook-engageable, free-standing loops along the length of the substrate, and has a substantially constant fiber density across its width. The array of fastener elements is arranged in a discrete band of fastener elements extending longitudinally along the substrate. The fastener product is useful as a repeated use bag closure, with a pair of grooves and a graspable rib integrally molded into the substrate between the fastener elements and loops. The center portion of the closure seals the bag until it is torn away to expose the mating bands of loops and fastener elements.Type: GrantFiled: November 21, 2000Date of Patent: December 2, 2003Assignee: Velcro Industries B.V.Inventors: William Clune, William H.

Patent number: 6524507Abstract: A process and apparatus for producing fastener elements comprising a base and a field of fastener elements molded with and extending from the base. The method includes applying molten resin under pressure to the surface of a mold roll, the mold roll consisting of a pair of adjacent molding rings. A first molding ring defines cavities that form base portions of the fastener elements and serve as channels allowing molten resin to pass through and into cavities defined by a second molding ring thus molding distal portions of the fastener elements. The fastener elements are constructed to engage loops of a mating loop component to form a releasable fastener. The fastener elements comprise hooks and spikes, interspersed among the hooks, which extend at an acute angle from the base. By arranging the hooks and spikes in differing directions on the base, increased shear strength is provided in corresponding directions.Type: GrantFiled: July 17, 2000Date of Patent: February 25, 2003Assignee: Velcro Industries B.V.Inventor: William Clune

Publication number: 20030031386Abstract: A reclosable bag has a closure including first and second fastener strips. The first fastener strip includes a strip form base having an array of discrete hook fastener elements integrally molded with and extending from the base. The second fastener strip includes loop elements engageable by the hook fastener elements. The polyethylene bases of the fastener strips are welded directly to the body of the mailer, which is formed of a coextrusion of polyethylene materials. One of the fastener strips is unattached to the bag body along most of its length, so as to avoid undesired opening by shifting of bag contents. The bag is useful as an interoffice mailing envelope, for example.Type: ApplicationFiled: August 12, 2002Publication date: February 13, 2003Inventors: William H. Shepard, William Clune
