  • the device is advantageously designed in such a way that the feed shaft of the retracted position is movable into a rest position. Such a shipment in the rest position should take place because the intake shaft with its lower End must be very close to the plate cylinder and in the Reaches into the printing unit.
  • the Feed slot removed from the plate cylinder and positioned in front of the printing unit is achieved, for example, in that the feed chute consists of a essentially vertical upper area and a lower area, which for Insertion of the pressure plate from the substantially vertical position to Plate cylinder is pivotable. This swiveling movement causes the lower part of the feed slot in the position in which the pressure plate for the Detection is kept ready by the leading edge tensioning device.
