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 the web layers provide a unique functionality to the product being manufactured.No laminate winding models exist in the literature.This paper will focus on the development of a laminate winding model and laboratory test verification of the model.Application:This model will be helpful to improve the quality of wound rolls of laminated webs by optimizing the winder operating conditions and the resulting wound roll residual stresses.Knowledge of these stresses can be used to prevent defects,such as blocking,slippage,and buckling.
