ABSTRACT:
A coreless roll of web material is made by winding a web material around a mandrel. The mandrel has a plurality of radially extending projections at spaced intervals. The free end of the web material is then pressed against the mandrel by a pressure roller for the initial winding of a roll. Affixing binder is applied to the pressure roller, and the web material is pressed between the pressure roller and the projections of the mandrel to transfer the affixing binder from the pressure roller to at least the first two windings of the roll whereby they are releasably affixed together. The web material is wound about the mandrel to provide a fully wound roll. The roll is thereafter severed from the remainder of the web material. The mandrel is then removed from the roll to render the roll coreless.
