In many cases, when the web is transported in a paper machine or a rotary press, the mechanism of wrinkle trouble by paper factor is not clear. Then, theoretical consideration was done by using FEM from the viewpoint of traveling performance of web about the condition that shear wrinkle which run on the roller and causes the trouble is generated by paper factor.
As a result, the possibility of causing the lateral motion of running web turned out depending on the factor of paper origin like orientation angle and tension profile. The reason is that the web is transported with shear deformation done on driving roller according to the load of tension.
In addition, the technique for analyzing the process that shear wrinkle caused by tension and lateral motion of web runs on the roller was examined. Although a huge number of element meshes was needed to express wrinkle by simulation, it was shown to be able to analyze the generation of wrinkle by using elastic-plastic analysis.
