Abstract: A sheet-fed printing press includes a plurality of printing units disposed along a sheet-transport path. A transport apparatus (3, 33, 40, 50, 66, 78) is disposed along the sheet-transport path. The sheets are transported through the printing units along the sheet-transport path and, after recto-printing, they are returned along a return-transport path which extends essentially in an opposite direction to the sheet-transport path. The printing press is thus enabled to print recto-and-verso while having a very short structural length.

Abstract: Method for supplying a printing unit of a printing press with ink which is solid at normal temperature includes supplying the printing unit with ink in the form of solid bodies, and melting the solid ink bodies in the printing unit and applying the ink in a molten state to a cylinder of the printing unit.

Abstract: A printing press has a plurality of in-line printing units in which substrates are transported along a rectilinear transport path. The printing units include several recto printing units and several verso printing units disposed along the transport path. A transport system, which transports the substrates through the printing units along the straight transport path, includes a first transport apparatus through the recto printing units, and a second transport apparatus through the verso printing units. A feeder assembly feeds the substrates to be printed from a feeder pile to the transport system. The feed by the feeder also follows a straight path which is coplanar with the path through the printing units. It is thus possible to print not only bendable substrates, but also rigid and stiff substrates such as carton, plastic, sheet metal, glass, and the like. The system further includes a turning apparatus for turning the substrates between the recto printing units and the verso printing units.

Abstract: Transfer cylinder with an electromotive drive unit includes a common bearing for a rotor of the electromotive drive unit and for the transfer cylinder, the bearing being disposed in a unit of a printing press supporting the drive unit and the transfer cylinder.

Abstract: Rubber-blanket cylinder engagement and disengagement device for a rotary printing press having a plate cylinder and an impression cylinder includes swivel arms whereon the rubber-blanket cylinder is journalled, the swivel arms being articulatedly connected to a frame of the rotary printing press, an actuating device for swivelling the swivel arms, and an adjustable stop device disposed at a side of the frame for limiting swivelling motion of the swivel arms so as to bring about a setting thereof in a rubber-blanket cylinder engagement position, the stop device having at least one supporting element formed with a large supporting surface by which the stop device cooperates with the rubber-blanket cylinder.

Abstract: A device for the coupling and uncoupling of a printing unit, said printing unit, with its plate cylinder, being engaged with a blanket cylinder in a first position and being disengaged from said blanket cylinder in a second position. Further, the device can be configured so as to additionally serve for a printing press, having at least two printing units assigned to one blanket cylinder, to be variably operated with optimal results. This is achieved in that the printing unit can be brought into a third position, wherein it is disconnected from the drive. Also contemplated herein is a method for coupling printing stands to one another in a printing press.
