Heat-activatable Adhesive Patents (Class 442/150)
  • Patent number: 5985438
    Abstract: A reinforcing tape for a slide fastener and a slide fastener having a pair of fastener tapes whose end portions are reinforced with the reinforcing tapes are disclosed. On the end portion of a fastener tape to which a pin-and-box separator of a slide fastener is fitted, a transparent film layer formed of a thermoplastic elastomer or a thermoplastic resin and a fiber reinforcement layer formed of either a reticular sheet of monofilaments or a thin-layer non-woven fabric of fibers manufactured from a thermoplastic resin of the same type as the transparent film layer are superposed through the medium of an adhesive layer, with the transparent film layer constituting itself a surface layer.

  • Patent number: 5912197
    Abstract: Filler strips made of a solid layer of thermal sealable material, such as separate strips of polyethylene film or other suitable thermal sealable films, are sequentially spaced on one side of a thermal sealable plastic mesh web at equal distance from one another. The pre-prepared web is used on a conventional form, fill and seal machine to form mesh bags having top and bottom fin seals with enhanced strength. The bag is primarily mesh so the product within the bag breathes easily. A thermal sealable print band may be located on the second side of the mesh. Different types of bags can be formed on different types of automatic form, fill and seal machines by modifying the specific configuration of the pre-prepared mesh web for the particular automatic form, fill and seal machine design.

  • Patent number: 5863847
    Abstract: A coated article comprising a backing and a binder is disclosed. The binder precursor is an energy-curable melt-processable resin containing an epoxy resin, a polyester component, a polyfunctional acrylate component, and a curing agent for crosslinking the epoxy resin. The binder precursor is cured to provide a crosslinked coating. The invention also relates to a method of producing such coated articles and a surface-treated porous cloth material.

  • Patent number: 5851161
    Abstract: A mesh panel for throwable and/or grippable objects such as footballs, baseballs, basketballs, baseball bats, etc. The mesh panel is formed from polyvinylchloride (PVC) and includes a plurality of openings surrounded by a plurality of connecting portions. The outer surface of the mesh panel is such that each of the connecting portions includes a plurality of rib portions which further enhance the ability to grip the mesh panel. The inside surface of the mesh panel has an adhesive coating which bonds to an outer surface of the object to which the mesh panel is attached when heat is applied to the mesh panel. The heating of the mesh panel also causes a sticky, resin-like outer surface to be formed. The mesh panel enables various objects such as footballs, baseballs, basketballs, baseball bats, etc. to be much more easily grasped, thrown and caught by individuals of all ages and sizes, and particularly by individuals such as small adults and children having relatively small hands.

  • Patent number: 5849131
    Abstract: Our unique process applies pressure sensitive hot melt adhesive to fiberglass insulation with improved adhesion to the insulation surface and the adjoining substrate. As opposed to the typical spray or bead extrusion methods, the preferred embodiment applies a ribbon of adhesive to the blanket and pulls it into the insulating glass with a vacuum. The adhesive penetrates the glass and becomes an integral part of the insulating blanket.

  • Patent number: 5652053
    Abstract: Combinations of IPN type molecular or intramolecular materials, which are thermoadhesive at temperatures not exceeding 90.degree. C. and which can be molded and shaped at said temperature, are characterized in that they contain a first rubber-like elastoviscous constituent having a softening point not exceeding 90.degree. C. and a second, semi-cristalline constituent essentially of the polyester type having a fusion temperature of 35.degree. to 80.degree. C. These combinations have controlled adhesiveness and adequate fluidity for application by hand particularly in do it yourself applications, orthopedics, sport and physiotherapy, and as an adhesive material on rough or porous bodies.
