Patent ID: 8100056

Claim:
A method for controlling a sheet material processing machine having at least one printing or coating group having a blanket cylinder and an adjacent cylinder carrying a printing form that is coupled to a direct drive and is decoupled mechanically from a main drive acting on a gear train of a plurality of sheet transport cylinders, said printing form carrying cylinder having an associated inking group with an inking group roller that can be driven by the main drive and gear train, comprising the steps of: exclusively driving the printing form carrying cylinder by the direct drive during a printing operation of the machine; interrupting printing contact in a contact zone of the printing form carrying cylinder with the adjacent blanket cylinder for cleaning; decoupling the inking group roller of the inking group on a drive side from the main drive and gear train for the sheet transport cylinders; coupling the inking group roller on the drive side to the direct drive for the printing form carrying cylinder; driving the inking group roller according to a cleaning program stored in a selection menu for an individual cleaning period at an individual rotational speed by the direct drive; decoupling the inking group roller from the direct drive for printing form carrying cylinder following the cleaning period; recoupling the inking group roller to the main drive and gear train and reestablishing printing contact between the printing form carrying cylinder following the cleaning period.
