  • Patent number: 9908322
    Abstract: A device one of adjusts and changes a dampening medium profile, which extends in the direction of a printing width, in a printing unit comprising at least one printing unit cylinder, at least one inking unit which inks the printing unit cylinder, and at least one dampening unit which interacts with one of the printing unit cylinder and the printing unit. A drying device, which extends over the printing width, is provided with a number I(I?, 0>1) of drying elements, the influence of which, on a printing unit surface to be treated, allows moisture to be removed from a number of n(n?, n>1) axial portions aj(j=1, . . . , n) that are offset relative to one another in the direction of the printing width. One of an extent of the influence of the drying device with respect to the axial direction (aj) and the operating state of the drying device can be varied independently of one another.

  • Patent number: 9533486
    Abstract: A printing press for security printing has an Orloff offset printing unit comprising a plurality of stencil cylinders which can be inked, in each case, by an associated inking unit, an ink-collecting cylinder which interacts with the plurality of stencil cylinders, an Orloff plate cylinder which interacts with the ink-collecting cylinder, a transfer cylinder which interacts with the Orloff plate cylinder, and an impression cylinder which forms a printing point with the transfer cylinder. At least the transfer cylinder which interacts with the Orloff plate cylinder in the thrown-on position is included by a first printing unit section and is mounted in or on a first part frame.

  • Patent number: 9486993
    Abstract: Rotational bodies of a printing press with at least a first, a second and a third ink-conducting rotational body, which interact with each other in pairs, can be set in a thrown-on position. The second of the at least three rotational bodies can be set both against the first of the three rotational bodies and against the third of the three rotational bodies in order to form a two-sided thrown-on position. Tracking, coupled in a defined way, of the rotational axis of the second rotational body takes place at the same time as a radial positional change of the rotational axis of the first rotational body, by the superimposition of two movements along two non-congruent movement paths which run in a plane which is perpendicular with respect to the rotational axis. A device for setting rotational bodies of a printing press is also provided.

  • Publication number: 20160279925
    Abstract: A gravure printing press utilizes a printing assembly with a printing forme cylinder that is twice as large in relation to the number of multiple copies which can be printed during one revolution. The printing forme cylinder, in a thrown-on position, forms a printing point with an impression cylinder which is twice as large in relation to the number of multiple copies which can be printed during one revolution. A wiping cylinder, in a thrown-on position, also interacts with the printing forme cylinder. An ink collecting cylinder, in its thrown-on position, interacts with the printing forme cylinder. A plurality of stencil cylinders, in thrown-on positions, interact, one after another, with the ink collecting cylinder on the circumference thereof. Each of the stencil cylinders can be inked by at least one inking unit. The ink collecting cylinder is configured with a circumference which is larger than the printing forme cylinder by an integral multiple.
