Winding mechanics of laminate webs

Abstract

Models that describe the residual stresses due to winding single layer webs at the end of roll-to-roll manufacturing machines are mature. These models have been used to reduce or avoid defects that are due to winding. Many laminated products exist where two or more webs have been joined to form a thicker composite web. The properties of each layer provide a unique functionality to the product. No laminate winding models exist in the literature. This paper will focus on the development of a laminate winding model and lab test verification of the model.
