  • Patent number: 8156865
    Abstract: A method for operating a printing machine in a print operating mode and another operating mode, for example a maintenance mode. In the print operating mode, bringing a vibrating roller periodically into contact with a first roller of an inking unit, driving the first roller rotationally by a first motor, driving a second roller of the inking unit rotationally by a second motor, transmitting no torque from the first motor to the second roller through a clutch therebetween, and activating the first motor by a control device causing the first roller to rotate at a rotational speed in a constant ratio to a rotational speed of the second roller. In the other operating mode, driving the first and second rollers rotationally by the first motor and transmitting torque from the first motor to the second roller through the clutch. A printing machine for carrying out the method Is also provided.

  • Patent number: 7625146
    Abstract: A system automatically cuts recording media into non-standard sizes and shapes. The system includes a support for supporting recording media, a feeder mechanism for transporting recording media onto the support, a cutting head having at least one cutting member, and a controller for actuating reciprocation of the cutting member so that the reciprocating cutting member cooperates with the support to pierce the recording media. The cutting head and feeder mechanism are controlled so that the cutting head is moved to positions for cutting the recording media as the recording media is advanced on the support.

  • Patent number: 7367265
    Abstract: A packing or dressing is mounted on a cylinder of a rotary printing press. A dressing suspension leg, situated at an end of the dressing extending in the production direction of rotation of the cylinder, is positioned in an opening in the surface of the cylinder. That suspension leg is retained in the cylinder opening predominantly by its own weight.
