ABSTRACT:
A method and a device for controlling the sheet inlet when starting up a sheet-processing printing machine having a vibrator-type inking unit, in which the sheets are positioned at front lays, their correct position is established and, in the case of the position having been established as correct, the sheet inlet is cleared at a particular machine position. The intention is to avoid the first entering sheet running into the printing machine in each case at different phases of the vibrator cycle in the case of a plurality of start-up operations. This is achieved according to the invention in that the first sheet is conveyed up to the positioning line, the feeder is then switched off and the sheet inlet is only cleared again when the vibrator gearing assumes a particular angular position.
