Abstract:
A winding device for flat printed sheets has a rotatably supported winding drum for receiving and dispensing printed sheets. At least one winding mandrel having a winding belt wound thereon and configured to unwind the winding belt and feed undershot the winding belt to the winding drum is provided. The winding belt receives the printed sheets and, by being wound onto the winding drum together with the printed sheets, forms winding layers of the printed sheets on the winding drum. A touch probe detects an empty state of the winding drum, without printed sheets wound thereon, or a loaded state of the winding drum, having printed sheets wound thereon, by interacting with the winding belt or the printed sheets.
