If a double sheet is detected, the double sheet is sucked through a suction nozzle, a signal is generated for the machine operator and he must remove the double sheet. In such double-sheet locks, the printing machine is brought to a standstill upon detection of a double sheet and must be restarted after removing the double sheet. This reduces the production capacity of the printing machine.
  • the DE 40 05 910 C2 shows a feed table of a printing press with a double sheet recognition and a device for separating out double sheets. If a double sheet is detected, it is discharged by means of a switch. Although this procedure makes it possible that the printing machine does not have to be stopped, however, the double sheet still represents waste. Also, due to the gap in the sheet flow in downstream units (eg display, stacking), process disturbances may occur.

  • the former double sheet can be transferred from its waiting position to the transport device so that it is fed to the printing machine as part of an uninterrupted sheet flow. In other words: Only the double sheet and not the whole machine is stopped, the double sheet then inserted into the sheet stream.
  • the suction device upon detection of a multiple sheet by the device for multiple sheet detection, the suction device is driven by the controllable drive briefly against its direction to temporarily transport the detected double sheet against the sheet transport direction. As soon as the preceding sheet has reached the intended distance from the former double sheet, the suction device is again regularly driven in the running direction and the former double sheet is fed to the printing machine as part of a continuous, uninterrupted sheet flow.

In the transfer area, and as long as the sheet is still held by the suction device, then carried out the implementation of a multiple sheet control. In the event that a multiple arc is detected, the suction device is briefly stopped or there is a brief reversal of the direction of the suction device. As soon as the preceding sheet has been transferred to the transport device and has the intended distance from the former multiple arc held by the suction device, the former multiple sheet is likewise transferred to the transport device. If no multiple sheet is detected, then immediately followed by a deduction of a next, uppermost sheet of a sheet stack through the suction device.

In the transfer region and as long as the sheet is still held by the suction device, a control of the descaling, i. the length of the shingles, also known as the degree of shallow, is measured. Upon detection of a deviation of the actual subsaturation from the desired subsaturation of the drive of the suction device is briefly stopped, briefly accelerated or decelerated or there is a momentary reversal of direction of the suction, so as to correct the Unterschuppung. The decision on the control of the suction device is made in response to the measurement result and can be carried out in particular in a machine control. If the actual subsidence coincides with the nominal oversupply, then the suction device continues to be operated unchanged.
