Sheet rotating or turning device for e.g. electrophotographically operating printing machine, has changing device for changing twisting degree or twisting angle of common twisting of transportation belt or strap

摘要

The device has a transportation body with a transportation belt (1) or strap for transport of sheets. Hoistways (5) of the transportation belt or strap running parallel to each other is guided between the sheets, where the transportation belt runs to deflecting bodies that are axis-parallel to each other. The transportation body is formed as a turning device by common twisting of the transportation belt or strap, where a changing device (8) is provided for changing a twisting degree or twisting angle of the common twisting of the transportation belt or strap.
