    摘要: 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.

    摘要: 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.

    摘要: A printing machine comprising a plurality of printing units (3) arranged in line one behind the other and an endless transport belt (4) for substrates to be printed, said transport belt running around, at least, two spaced-apart rollers (5, 6) and past said printing units. At least, two rollers (5, 6) are mounted on a coherent belt-carrying unit (9) from which, when being in a slack condition, said transport belt (4) may be stripped off. Furthermore, the printing machine features a drawer (24) which may be pulled out laterally and which is provided below said belt-carrying unit (9) as well as a holding device (11, 12, 13, 15, 16) holding said belt-carrying unit (9) and being switchable between, at least, two different conditions, in a first condition said holding device holding said belt-carrying unit in an operating position, and in a second condition said belt-carrying unit (9) resting loosely on said drawer (24). This permits a simple and quick belt changing.

    摘要: A document printer/copier comprises a pair of drum-support members for rotatably supporting an image-recording drum and, optionally, an intermediate image-transfer drum. At least one of such drum-support members is adapted to be decoupled from the drum(s) it supports and be moved to a position within the machine frame in which it does interfere with the replacement of the drum(s)'s outer layer. Preferably, such member comprises a selectively energizable clamp which, when energized, clamps onto an axle bearing of a drum and thereby supports the drum for rotation. When de-energized, the clamp releases the drum bearing, enabling the drum-support member to be slid axially along the drum axis to a position spaced from the drum axle, and thereafter pivoted to a position spaced from the drum axis where it does not interfere with drum servicing and/or replacement.
