Abstract: A mechanical fastener including a plurality of engaging stems located in unordered arrangements, which repeat on a substrate. A preferred embodiment of the invention provides a mechanical fastener with a plurality of repeating unordered arrangements, where the arrangements repeat in more than one direction. The unordered arrangements of the engaging stems allow pairs of the fasteners to interengage with themselves, or in other words, to self-mate. Additionally, the unordered arrangements of engaging stems allow the fasteners to interengage at any relative angular orientation with a relatively constant engagement force, and a relatively constant disengagement force regardless of their angular orientation. The unordered arrangements of engaging stems also allow pairs of fasteners to interengage at any relative planar position with a relatively constant engagement force and a relatively constant disengagement force regardless of their planar position.

Abstract: The present invention provides a banding system, banding tape and method of using the same, each of which is particularly useful a variety of items such as flowers, straws, pens, pencils, newspapers, and vegetables. The banding system comprises a first strip and second strip. The first strip comprises an elastic polymeric material having a percent recovery of at least 50% after being elongated to 100% of its original length. The first and second strips are capable of being bonded together. The banding tape comprises a strip of elastic polymeric material having inner and outer surfaces and a nontacky layer on at least a portion of at least one of the surfaces. The method of using the banding system or tape of the invention comprises the steps of collecting one or more objects into a bundle, wrapping, stretching and securing the system or tape around the bundle, and allowing the elastic strip to at least partially recover to exert a compressive force on the bundle which holds the bundle together.

Abstract: A flame retardant fastener adapted for releasable engagement to a second fastener. A backing layer of the fastener is constructed of a flame retardant polymeric material having an exposed bonding surface and a support surface. A multiplicity of flexible, resilient stem portions extend generally perpendicular to the bonding surface. The distal stem portions have an enlarged head portion located on a distal end of the stem portion. The enlarged head portions have a top surface opposite the distal stem portions and a latching surface opposite the bonding surface. The head portions is disposed to afford movement along different portions of the backing layer and into releasable engagement with the second fastener. A non-flame retardant, pressure sensitive adhesive is applied the support surface.

Abstract: A patch is provided for repairing articles such as bicycle tire inner tubes. The patch includes a backing; and a pressure sensitive adhesive layer having an average thickness of greater than about 0.076 mm disposed on the backing. The patch has a maximum thickness of no greater than about 0.64 mm, a T-Peel strength from an organic polymeric substrate of greater than about 0.18 kN/m after 1 hour dwell time at 22.degree. C., and a static shear strength of at least about 50 minutes from stainless steel at 70.degree. C. with a 7.6 kPa load.

Abstract: A reclosable mechanical fastener comprising a fastening component having a surface structure by which two such fastening components can become releasably attached. The novel fastening component is a composite of a tough substrate and a fastening layer that forms said surface structure, which fastening layer is formed from a cured oligomeric resin composition having one or more like or different hard segments, one or more like or different soft segments, and one or more like or different monovalent moieties containing a radiation-sensitive, addition-polymerizable, function group. The novel fastener forms stronger linkages than were possible with similar fasteners of the prior art.

Abstract: An article is provided which comprises a polyolefin first substrate adhered to a second substrate with an epoxy adhesive. The polyolefin first substrate has graft-polymerized thereto at least one monomer selected from the group consisting of sulfonic and carboxylic acids and alkyl esters thereof containing fewer than eight carbon atoms in the ester group, amides, and mono- and di-substituted amides, alcohols, amines, and 5-, 6-, and 7-membered heterocyclic rings having at least one oxygen and/or nitrogen atoms in the ring, with the proviso that said monomer contain an ethylenically unsaturated polymerizable moiety. The graft-polymerized monomers are in a layer less than 5 micrometers in thickness and contact the epoxy adhesive.
