Stresses within rolls wound in the presence of a nip roller
Abstract
Models which can be used to calculate the internal stresses within wound rolls of web material have all been confined to the center winding technique to date. In this publication a new boundary condition is presented which will allow existing models to calculate the internal stresses within a wound roll which has been center wound with an undriven nip roller impinged upon the outside of the roll. Experimental verification of the new boundary condition is presented. The mechanism by which a nip roller can increase the wound in tension in the outer layer of the wound roll is presented.
