ABSTRACT:
A core upon which may be wound a strip of material, more specifically, a strip of labels attached to a liner by an adhesive. The core includes a tube having circular cylindrical symmetry and a coating of a temporary adhesive. The adhesive should have less tackiness than that holding the labels to its liner. In more general terms, the adhesive attached to the tube for holding the web should have a tackiness that should not require a pull force to remove common bond paper from the core of more than about five ounces per inch of width with a 90 degree pull. The adhesive should appear at some axial location over at least 85 percent of the circumference of the tube. Preferably, it will occur on at least 95 percent of the circumference. Making the core involves permanently attaching the adhesive to a tube having cylindrical symmetry. Attaching a web proceeds, after making the core, with contacting the core with the web and then rotating the core about the tube's axis of cylindrical symmetry.
