Abstract
The invention relates to a device for turning sheets. A sheet to be turned is guided into a gap between two transport elements moving in opposite directions and is pressed against the reverse-moving transport element or the forward-moving transport element depending on whether or not said sheet should be turned. The following transport elements then guide the turned or unturned sheet to the output of the device. The device preferably is configured such that the same transport time is required for turned and unturned sheets so that the order of the sheets and the interval between the sheets upstream and downstream of the turning device remain the same.
Claims14
A device for selectively reversing the orientation of sheet material comprising:
- forward transport elements configured to transport the sheet material along a forward transport path;
- and
- reverse transport elements configured to transport the sheet material along a reverse transport path, said forward and reverse transport elements defining a clearance therebetween whereat the sheet material enters traveling along the forward transport path;
- wherein said forward and reverse transport paths individually direct the sheet material to a single one output of said device;
- wherein the transport path of the sheet material is selectively reversed by a first guiding element positioned along said clearance and configured to move transversely across said clearance by an actuator arranged to urge the sheet material against said reverse transport elements so that the sheet material is transported along said reverse transport path to said output, non-reversed sheet material continuing along said forward transport path to said output.
