METHOD FOR PRODUCING CORELESS ROLLS OF PAPER

摘要

A method of forming a roll of convolutely wound web material. The method includes applying adhesive to an elongated mandrel, winding web material around the mandrel to form a roll of convolutely wound web material, rotating the mandrel relative to the roll to smear the adhesive, and removing the mandrel from the roll. The smearing can be in a circumferential direction. The adhesive can be applied longitudinally along the mandrel. The adhesive preferably has a viscosity within the range of 3000 to 18,000 cps. Preferably, the method includes pulling the mandrel longitudinally before the step of removing the mandrel from the roll. The pulling can reduce the mandrel diameter and/or can increase its length. The rotating can be conducted before the pulling, during the pulling or during the winding. The rotating can be conducted before or during the removing. The web material can be bathroom tissue or kitchen towel.
