Grip drive for direction changing drum

摘要

The grip drive for a grip (7, 12) in a direction changing drum has a grip system for single-sheet or sheet-wise printing and at least one further sheet holding system (5) used only for sheet-wise printing. The grips consist of a grip stop (7) on the grip turning shaft (8) and a grip tongue (12) on the grip shaft (11). The grip is controlled by a transmission (6, 14, 13) with pre-switching transmission (17-20) in front of it.
