Abstract
An apparatus and method for winding stiffened coreless rolls which include a spiral wound roll formed from this product paper, conventionally paper having a printed pattern or design on one side, and a spiral stiffener sheet extending completely around the roll to stiffen the roll. The apparatus receives continuous webs of product paper and stiffening paper, severs the stiffening paper into short lengths for winding into the roll of product paper and automatically feeds the stiffening sheet onto a length of product paper which is wound into a roll. The two webs are fed to either side of a continuous rotating cutter roll. Anvil assemblies are moved into engagement with a knife carried on the cutter roll for selectively severing the webs as required.
