A foam roofing underlayment is provided with a reinforcement membrane having an array of fastener elements for engaging fastener elements on a flexible roof membrane. The underlayment is formed by molding foam between the reinforcement membrane and a carrier membrane. The underlayment in secured to the roof using washers having fastener elements for engaging the fastener elements of the flexible roof membrane. An anti-peel flap with fastener elements is provided around the periphery of the washers. A slip sheet is used between the underlayment and the flexible roof membrane to permit accurate positioning of the flexible roof membrane prior to engagement of the fastener elements. The interstices between the fastener elements provide lateral moisture paths to vents in the flexible roof membrane.

Membrane roofing

A reclosable package that includes a pouch of flexible material that includes a reclosable closure secured to the flexible material adjacent an opening to releasably retain the opening of the pouch in a closed state. The closure includes fastenable closure strips that extend along opposite sides of the opening and that are releasably fastenable in multiple relative positions spaced along each of two perpendicular directions. The closure and flexible material of the pouch are configured to provide a maximum stiffness, in resistance to bending about a pouch axis extending along the pouch perpendicular to the closure strips, as determined at a point along the closure with the closure strips fastened, that is more than 10 times the maximum stiffness, in resistance to bending about the pouch axis, of one of the closure strips as secured to the flexible material, as determined at the point along the closure with the closure strips unfastened.

Reclosable pouch closures and related packaging and methods

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.

Composite hook and loop fasteners, methods of their manufacture, and products containing them

Forming construction underlayment

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.

Hook-engageable fastener sheets, and methods and articles of manufacture

A fastener product includes an elongate strap, projections molded of resin extending from a first region of the strap, and a head element molded of resin extending from a second region of the strap. The head element includes a hole sized to receive an end of the strap.

Fastener products

A medical wrap includes a flexible, sheet-form substrate with a discrete medical function delivery region having a surface adapted to be placed against a patient's skin to provide a desired medical effect. The substrate carries a field of fibers exposed on one side thereof for engagement by fastener elements, and an array of fastener elements extending from a side of the substrate opposite the exposed fibers. The fastener elements each have a respective stem extending integrally from a film of resin disposed in a band across the substrate and encapsulating surface features of the substrate. The fastener elements are constructed to snag the exposed fibers when the substrate is wrapped about a patient in an overlapping manner, to secure the wrap about the patient with the medical function delivery region in a desired position. The wrap is useful as a hot or cold pack, medical dressing or drug delivery device.

A carpeted surface is protected with a temporary carpet protection sheet that includes a lightweight non-woven or knit fibrous material laminated with a resin backing into which at least portions of fibers of the fibrous material are embedded, or to which resin of the fibers is directly and chemically fused. Male touch fastener elements extend along the backing and are arranged in spaced apart fastening regions adjacent the longitudinal edges of the fibrous material. The male touch fastener elements are configured to be both releasably engageable with the hook-engageable fibers of the fibrous material, when the protection sheet is arranged in overlapping fashion, and releasably engageable with looped carpet tufts. A protection system features multiple lengths of such protection sheet joined by hook seaming tape.

Temporary surface protection

A material for covering a surface of a home or building is provided in the form of a flexible laminate having a fastening side comprising a sheet-form fastener component, and an opposite side formed by a sheet of paper laminated to the fastener component to increase the dimensional stability of the fastener component for covering and fastening over a wide area. The fastener component can have either hooks or loops. The laminate is particularly useful for laying flooring with low backlash between adjacent pieces.

Flexible building construction laminates with fasteners

A method of making a fastener product having discrete regions of fastener element stems extending from a strip-form base includes providing a gap formed along a peripheral surface of a rotating mold roll, the mold roll having a plurality of cavities exposed about the peripheral surface. A sleeve is introduced to the gap. The sleeve is positioned about the mold roll and covers selected cavities. Molten resin is introduced to the gap such that the resin forms at least a part of the strip-form base of the product at the peripheral mold roll surface and at least partially fills a plurality of the cavities to form fastener element stems as projections extending from the strip-form base, while the resin remains blocked from said selected ones by the sleeve. The resin is solidified and stripped from the peripheral surface of the mold roll by pulling the projections from their respective cavities.

Forming discrete fastener element regions

A method of filling a bag that includes inserting an insulator between first and second side walls of a closure strip and joining an outer surface of the second side wall of the closure strip to an inner surface of a bag wall in a region of the wall behind which the insulator is positioned.
