A multi-color printing machine comprises a print carrier supplying system including a print carrier supply unit, a print carrier transporting unit and a print carrier discharge unit, and a printing image supplying including at least two printing mechanisms each having a plate cylinder and an offset cyinder, the offset cylinders being arranged in contact with one another and of the offset cylinder being arranged in contact with the print carrier transporting unit, the print carrier transporting unit being formed as a central printing cylinder which cooperates with the print carrier withdrawal unit and with the print carrier supply unit and is provided with at least one gripper element, the printing image supplying system also including an endless band-shaped printing image collecting element associated with at least first and last of the offset cylinders of first and last of the printing mechanisms through at least one connecting cylinder.

Multi-color printing machine

A control system for controlling a plurality of subprocess means, for example adjustment drives for ink zone adjusting screws in a plurality of modes of operation. The control system includes an input device, a start device and a number of control subsystems arranged in groups and connected to respective selection systems. The latter are in turn connected to a main control selection circuit which is in connection with the start device. Each group of the control subsystems and each group of the control selection circuits are connected via a first control code bus and a second control code bus, respectively, to the main control selection circuit.

Control system for printing machines

A hydraulic drive for a multi-color, sheet-fed rotary printing machine assembled of a plurality of consecutively arranged press units each having a set of sheet-processing cylinders and gear trains interconnecting the cylinders, is constituted by the following combination:

A printing press includes an impression cylinder formed with axially directed channels for sheet-clamping means, a radiant dryer arranged above the impression cylinder to radiate heat on the printed sheet, a screening hood mechanism tiltably mounted for movement between an inactive position in which the sheet is exposed to heat rays from the dryer and a screening position; the driving motor is connected to the power source by two parallel power supply circuits each including a separate switch, one of the switches being actuated by a relay which in turn is actuated by series-connected contacts closed respectively when the dryer is in operation, when the driving motor is disconnected, when the printing machine stops, and when the channel for the clamping means on the impression cylinder is not facing the dryer.
