A winding simulation model predicting the internal stress state of a wound roll would provide an indispensable tool for the optimal selection of the winding parameters and, above all, a fast way to design new winding concepts - such as winding drum covers and winding geometry. Hence, the nip-induced stresses and nip-induced tension are of the outmost interest to the manufacturer of the winding apparatus. In this thesis, a rigorous contact mechanical model for the winding nip is presented. Under the assumptions of the linear elastic web and paper roll material and compliant winding drum, the indentation, stick and slip equations are derived. The wound-on-condition, a mathematical statement for the initially free sheet becoming finally a part...
