The winding process of web materials with low bending resistance is composed of several partial processes whose single effects are influenced by specific machine, process and material parameters. The interaction of these processes causes an essential increase in the difficulty of modeling the total process. Up to now there are numerous mainly experimental investigations concerning the particular effects of the winding process. But they are not sufficient to describe the total process regarding all influences of the machine technology and material properties.In this regard our institute has developed a systematology of models for winding mechanics which starts with the real winding process of the different winder classifications and resolves the complex total process step by step into partial models. Subsequently it is possible to study the effect of different parameters on the derived partial models based on various degrees of idealisation. By coupling different partial models the modelling of any partial process becomes possible.The fundamental knowledge of theoretical research work is the mechanic of solid bodies with its analytical methods for highly idealized [simple] models and numerical methods (finite elemente-method (FEM), finite-difference-method (FDM)) for complex, more realistic models
