Publication number: 20040130056Abstract: Improvements are disclosed for an apparatus for continuously molding small fastener elements integral with a base web from a flowable resin. The apparatus comprises a cylindrical mold roll rotatable about an axis and defining small fastener element-shaped mold cavities in the surface thereof, and pressure-applying means to apply operating pressure to force the resin into the cavities at a pressure zone. The pressure-applying means and mold roll define a mold gap therebetween for forming the base web. The advantageous use of relatively long mold rolls, to produce a correspondingly wide web, and the use of higher molding pressures, e.g. to form very small fastener elements, is enabled by various improvements, including means to maintain the mold gap at a desired thickness profile across the length of the molding region of the mold roll under operating pressure. In some cases the pressure-applying means includes a pressure roll, in other cases it includes a resin nozzle assembly or pressure head.Type: ApplicationFiled: November 24, 2003Publication date: July 8, 2004Applicant: Velcro Industries B.V., a Netherlands CorporationInventors: Andrew C.

Publication number: 20040067342Abstract: Lightweight, hook-engageable materials capable of functioning as hook-engageable fasteners are treated and configured for use for economical and attractive displays and decorations. Laminates of the material with various substrates with associated printing are used to form visually attractive point of purchase, merchandise or trade show displays. Self-supporting or stable materials having lettering or designs on their surface are used to form banners or floor coverings. Non-woven materials with varied areal density of fibers perform those functions with particular economy. Low density knit fabrics are also useful according to broad features of the invention. Methods are shown to produce reinforced corrugated board and desirably laminated and printed materials having hook-engageable surfaces.Type: ApplicationFiled: September 8, 2003Publication date: April 8, 2004Applicant: Velcro Industries B.V., a Netherlands corporation,Inventors: William H.

Publication number: 20030135964Abstract: A hook fastener member having rows of molded hook-shaped fastener elements that lie in planes aligned with the rows, with generally planar plate portions at the outermost ends of at least some of the fastener elements, the plate portions lying generally parallel to the base of the fastener member. The plate portions can enhance engagement of the hook fastener members with mating loop fastener members, particularly with low loft non-woven loop fastener members. A method of making fastener members is provided. Molten resin is extruded and applied to a molding roller, creating preforms. The outermost portions of at least some of the preforms are flattened, thereby forming generally plate shaped portions.

Publication number: 20030127769Abstract: A fastener for engaging loops includes a base with a field of fastener elements molded with and extending from the base. 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. Molds and methods for forming the fastener are also disclosed.Type: ApplicationFiled: February 25, 2003Publication date: July 10, 2003Applicant: Velcro Industries B.V., a Netherlands corporationInventor: William Clune

Publication number: 20030101549Abstract: A woven fastener product includes an array of hook elements and an array of loop elements that extend from the surface of different respective regions of a common fabric base. The arrays are formed by warp yarns, the arrays being separated in the warp direction of the fabric base. To form a self-engaged fastening, the fastener product is conformed so that the hook elements overlie the loop elements. Monofilament loops are shown sized and located to provide pin-receiving mounting sleeves as part of the woven structure.Type: ApplicationFiled: January 14, 2003Publication date: June 5, 2003Applicant: Velcro Industries B.V., a Netherlands CorporationInventors: Der-Shi Wang, David E.

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: 20020185192Abstract: A woven fastener product is shown in which monofilament loops woven in the structure are shown sized and located to provide pin-receiving mounting sleeves as part of the woven structure to fasten a device or object to the woven structure. In one case, a pair of sleeves has a pre-determined spacing corresponding to the spacing between a pair of mounting pins of a pre-determined device such as a wrist watch. In another case, an extensive field of mounting sleeves formed by a series of adjacent, parallel rows of the sleeves enable the mounting on the same band of different devices having different mounting pin spacings, e.g., to enable different size watches to be used on the same type of band. The mounting loops lying between those that correspond with the particular mounted device provide a cushioning effect adding to comfort and secure positioning of the watch or other device on the band.Type: ApplicationFiled: July 30, 2002Publication date: December 12, 2002Applicant: Velcro Industries B.V., a Netherlands corporationInventors: Der-Shi Wang, Pamela C.

Publication number: 20020125605Abstract: Methods of forming mold cavities suitable for hook and loop fastening are disclosed, along with effective hook construction and hook and loop fastener products that have an ultrathin cross-section. Photochemical techniques are employed to form plates that define hook-form mold cavities, and, alternatively, chemical etching is employed following preforming of the cavities and machining. Hooks having three-dimensional tapers with enhanced loop engaging characteristics are disclosed. By utilization of special surface finishes and tolerances, hook fasteners, having ultrathin cross-sections are realized, that pave the way for practical use of touch fasteners in a wide range of new areas.Type: ApplicationFiled: December 21, 2000Publication date: September 12, 2002Applicant: Velcro Industries B.V. a Netherlands CorporationInventors: Thomas G.

Publication number: 20020029441Abstract: 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: ApplicationFiled: November 20, 2001Publication date: March 14, 2002Applicant: Velcro Industries B.V., a Netherlands corporationInventors: William H.
