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.
