In replacing a sleeve on a printing machine drum, the diameter of the drum is reduced by moving the drum parts toward one another to facilitate removing the sleeve, and/or mounting another sleeve onto the drum, and increasing the drum diameter by moving the drum parts away from one another.

Sleeve on a drum and changing said sleeve

A fuser roller for a printing machine that is equipped with internally located heating elements and has a cylindrically shaped body that is closed off at each end by flanges. At least one connecting element, that is moveable in a rolling motion, is provided between the body and the flanges. A spring plate urges the flange, via an offset that has a chamfer, against the connecting element that is located inside an annular groove. The annular groove can also have a chamfer. Changes in the connection can be balanced out by movements of the connecting elements and commensurate pulling up of the flange by the spring plate.

Connection between the flange and the body of a fuser roller

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

Replaceable cylinder element including cylindrical sleeve and end members having complementary centering faces

The invention concerns a device for assembly of tubular cylindrical carriers ( ) on the circumference ( ) of carrier cylinders ( ) of drums or cylinders, wherein for the assembly of the tubular carrier ( ) on the lateral surface ( ) a pressure medium acts upon the latter. By attaching an assembly aid ( ), on which a tubular carrier ( ) can be held, on the carrier cylinder ( ), a pressure medium acts upon the latter, so that positioning of the tubular carrier ( ) is made possible.

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.

The invention concerns a printing apparatus including a cylinder, mounted in side walls, that has a sleeve-shaped sheath that can be replaced through an opening in a side wall. The object of the invention is to develop a printing apparatus in which replacement of a sleeve-shaped sheath is simplified, and the risk of damage to the sheath is reduced. The invention proposes that a detachably attached sheath (,) that projects laterally from the cylinder (,) on the side toward the opening be provided on the enveloping surface (,) of the cylinder (,); that a holding apparatus (,), which can be set against and moved away from the interior of the projecting part (,) of the sheath (,), be provided for the sheath (,), the holding apparatus (,) being physically integrated with a bearing element (,) of the cylinder (,); and that in order to replace the sheath, the bearing element (,) can be positioned in a location which uncovers the opening. The invention is applicable to electrostatic, electrophotographic, and magnetographic printing apparatuses.

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.

Printing machine with a sheet-transport belt

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.
