摘要： A cylinder with a functional layer (23) and with a supporting body (1), which passes through the cylinder. On the supporting body (1), a sleeve that accommodates the functional layer (23) is supported at ends (2, 5). The supporting body (1) is for its part accommodated on supporting elements (10, 11, 13) provided on the frame side. The cylinder sleeve (3) that accommodates the functional layer (23) can be centered in relation to the axis of rotation (8) by centering faces (6, 7) formed at the ends (2, 5). One end of the cylinder can be exposed at the supporting element (13).

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 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.
