ABSTRACT:
In order to set the sheet guidance devices of a folder simply and quickly for the production of once or twice cross-folded products and to guide the products reliably and carefully, a tongue and a tongue bar are arranged in the runout gap of the folding blade cylinder and gripper/folding knife cylinder. To produce twice cross-folded products, the tongue can be moved out of the runout gap, after which a guidance device with a somewhat arc-shaped contour is directed to the runout gap.
