Patent number: 6598276Abstract: Lightweight, non-woven loop products for hook-and-loop fastening are disclosed, as are methods for making them and end products employing them. The products are non-woven webs of entangled fibers of substantial tenacity, the fibers forming both a sheet-form, bonded web body and hook-engageable, free-standing loops extending from the web body. The product is, in important cases, stretched before bonding to produce spaced-apart loop clusters extending from a very thin web of taut fibers. In important cases a binder is added to stabilize the product in its stretched condition. An example of the loop product is produced by needle-punching a batt of staple fibers in multiple needle-punching operations, applying a foamed acrylic binder, and then stretching the needled batt and curing the binder with the batt stretched. Other forming techniques are disclosed and several novel articles employing such loop products are described.Type: GrantFiled: November 20, 2001Date of Patent: July 29, 2003Assignee: Velcro Industries B.V.Inventors: William H. Shepard, Paul R. Erickson

Publication number: 20030074768Abstract: A composite hook and loop fastener in the form of an elongated strip has an elongated loop component, a hook component permanently affixed to the loop component, and a backing layer disposed on a face of the wrap tie in a discrete region. The backing layer is used for permanent attachment of the wrap tie to a supporting surface. One end of the loop component is available for encircling an object to be wrapped and engaging the fastener elements of the hook component. The loop component has a self-supporting web of entangled fibers, the fibers forming both a sheet-form body and hook-engageable, free-standing loops extending from at least one surface of the body, and the hook component has fastener elements extending from a common base. The backing layer may be a pressure sensitive adhesive or a synthetic resin.Type: ApplicationFiled: October 15, 2002Publication date: April 24, 2003Applicant: Velcro Industries, B.V., a Netherlands corporationInventors: William H.

Publication number: 20030061692Abstract: A reclosable closure consists of two longitudinally continuous strips and which, when facially engaged, are held together by hook and loop fastening principles. The inner side of one strip has two fields of hook-engageable loops, separated by a female seal profile portion. The inner side of the other strip has two fields of molded hook elements arranged to engage the loops to hold the closure in its closed condition, and a central male seal profile portion for engaging the female seal profile portion to form a seal when the closure is closed. Another reclosable closure is held together by hook and loop fastening principles and includes a resilient bead that is compressed between opposing sides of the closure, or between spaced rails of an opposing side of the closure, when the hooks and loops of the closure are engaged. The closure is useful, for example, as a bag closure.Type: ApplicationFiled: October 2, 2002Publication date: April 3, 2003Applicant: Velcro Industries B. V.Inventors: Howard A. Kingsford, William H. Shepard, Paul A. Dandurand

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

Publication number: 20020095130Abstract: A self-adhesive garment closure for a garment includes a pair of opposed cooperating fastener elements, each having an exposed layer of self-adhesive material exhibiting strong adhesion to itself while remaining relatively tack-free to other materials. At least one of the fastener elements has a layer of foam material beneath the self-adhesive material, such as for increased bending stiffness. In some cases, such as for pull-up diapers, the self-adhesive closure is non-releasable once secured. Some closures also have cooperating hook-and-loop elements.Type: ApplicationFiled: January 12, 2001Publication date: July 18, 2002Inventors: Christopher R. Seitter, William H. Shepard

Publication number: 20020022108Abstract: Fastenings, including stretchy or flexible “zebra-like” and “leopard-like” appearing materials, are disclosed having spaced bands or a distribution islands of molded loop-engageable hooks or molded pre-forms for hooks, between which are bands or regions of different character. Molding is by rigid molds filled from the base region of the stems. In embodiments, linear bands or islands of fastener elements are themselves inextensible in the direction of their extent and comprise multiple rows of fastener elements. For ease of forming a uniform, elastically stretchy or flexible product, the bands or islands of fastener elements extend in the machine direction during manufacture.Type: ApplicationFiled: March 14, 2001Publication date: February 21, 2002Inventors: K.

Publication number: 20020000488Abstract: A dispenser for strip materials, e.g. hook and loop fastener material, which automatically finds formations in a continuous fastener strip during its dispensing and, at that point in the dispensing procedure, produces a resistance to the remaining supply, that enables parting of the lead unit from the remaining supply, thus dispensing a discrete unit. The dispenser has a receptacle to hold the supply of fastener strip material; it employs a retarding device to provide light drag against the motion of the strip as the leading strip unit moves from the dispenser in response to pull by a user. A detent downstream of the retarding device engages a corresponding formation in the strip material to resist movement of the remaining strip material, so that the strip ruptures along a line of weakness under a user's tension. Also disclosed are dispensable fastener strips of various forms, some advantageously formed by use of needled bat, and methods of forming the fastening strips.Type: ApplicationFiled: May 22, 2001Publication date: January 3, 2002Applicant: Velcro Industries B.

Patent number: 6202260Abstract: 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 6, 1998Date of Patent: March 20, 2001Assignee: Velcro Industries B.V.Inventors: William Clune, William H.
