  • Publication number: 20030099780
    Abstract: A process for making a fibered composition, including providing a coatable composition with a polymerizable adhesive composition and inorganic fibers, polymerizing the coatable composition to produce a fibered bulk polymer, and hot melt coating the fibered bulk polymer onto a first substrate to form a dispensable fibered adhesive layer. The fibers in the adhesive layer preferably have a mean fiber length of about 10 mils (0.25 mm) to about 60 mils (1.50 mm) and a range of fiber lengths from about 1 mil (0.025 mm) to about 100 mils (2.50 mm).

  • Patent number: 6216422
    Abstract: A wrapped mass of material. A preferred embodiment of the invention provides a cold-flowable material such as a hot-melt adhesive wrapped in a liner such that the liner is easily removed from the material. The present invention also provides a method and apparatus for wrapping the material with the liner. The wrapped mass of material comprises a flexible liner and a mass of material including a peripheral surface. The liner includes an inside surface, an outside surface opposite the inside surface, a first edge, and a second edge opposite the first edge. The inside surface of the liner is at least partially wrapped around the peripheral surface of the mass of material forming a wrapped mass of material. The wrapped mass of material is spirally wound about itself.

  • Patent number: 5848696
    Abstract: An elongate mass of material wrapped by a liner in which the liner is wrapped around the material with the liner inside surface facing the peripheral surface of the material, with first and second regions of the liner extending away from the material with the liner inside surface of the first region in unbonded contact with the liner inside surface of the second region so as to enclose the material with said liner. The material and the center region of the liner together form a core of the wrapped mass of material, and the first and second liner regions together form a tab of the wrapped mass of material. The wrapped mass of material includes a first portion and a second portion and is arranged such that the core of a second portion applies sufficient force to the tab of a first portion so as to maintain the mass of material enveloped by the liner at the first portion. Also presented are methods and apparatus for wrapping and unwrapping such material.
