Abstract
A method of operating a printing machine including a printing form cylinder and an inking unit for inking the cylinder, the inking unit having at least one inking unit roller rotatably driven at a speed different from the peripheral speed of the printing form cylinder, includes rotatably driving the at least one inking unit roller at the differential speed and at a relative speed that is different from the peripheral speed of the printing form cylinder, in time-dependence upon various operating states of the inking unit; and a printing machine for performing the method.
Claims18
A printing machine having a printing form cylinder and an inking unit for inking the cylinder, the inking unit comprising at least one inking unit roller drivable by a rotary drive at a differential speed with respect to the peripheral speed of the printing form cylinder, said rotary drive of said at least one inking unit roller being constructed so as to be changeable over in time-dependence upon various operating states of the inking unit, so that said rotary drive drives said at least one inking unit roller at the differential speed in a first operating state, and drives said at least one inking unit roller at another relative speed in a second operating state.
A method of operating a printing machine, which comprises:
- providing a printing form cylinder and an inking unit for inking the cylinder, the inking unit having at least one inking unit roller rotatably driven by a rotary drive;
- rotatably driving the at least one inking unit roller at a first differential speed different from a peripheral speed of the printing form cylinder and at a second differential speed different from the peripheral speed of the printing form cylinder, in time-dependence upon various operating states of the inking unit.
