  • a sheet control is carried out with regard to double and missing sheets and stopping the sheet transport depending on the result of sheet control. If a double or missing sheet is found, the removal of further sheets from the feeder stack is stopped immediately and the number of sheets preceding the double or missing sheet in the sheet transport direction on the conveyor line is determined, which can still be fed into the printing press and printed before the double sheet. or missing sheet arrives at the front marks of the plant.
  • the ink supply is turned off.
  • the stopping of the sheet transport after stopping the sheet removal from the feeder pile takes place exactly when the double or missing sheet reaches the system.
  • the number of sheets still to be conveyed into the printing press is determined from the distance between the machine and the sheet control in conjunction with the degree of underflooring in the case of underfed sheet feed and the format length of the sheets.
  • the running speed of the conveyor belt for conveying the scaled sheet is variable independently of the operating speed of the machine according to predetermined speed profiles, so that when starting or stopping the investor, the conveyor belt can be stopped and / or started according to a predetermined acceleration profile.
