A printing cylinder assembly for a printing machine includes a rotating shaft pivotally supported at one axial end shaft section thereof in a cantilever structure, and a sleeve cylinder removably mounted on the rotating shaft so that the cylinder can be fitted on and extracted from the rotating shaft from the other axial end side of the rotating shaft. The rotating shaft is formed at one axial end side thereof with a sleeve cylinder supporting tapered surface, and the sleeve cylinder is formed at one axial end side of an inner diameter portion thereof with a tapered surface, whereby the tapered surface of the sleeve cylinder can be fitted on and in close contact with the sleeve cylinder supporting tapered surface of the rotating shaft and thereby detachably coupling one axial end portion of the sleeve cylinder with one axial end portion of the rotating shaft.

An anilox roller for flexographic printing machines, which comprises a sleeve cylinder rotatably supported about its own axis by the fixed structure of a flexographic printing machine, and an anilox sleeve, which has a tubular body provided, on its outer side wall, with an anilox surface which can be axially fitted on and removed from the sleeve cylinder. Forced circulation of a temperature control fluid within the tubular body is further provided.

The present invention provides a printing assembly which includes a printing drum such as an impression drum, a pair of eccentric bearings between and on which the drum is mounted for rotation, a pair of self aligning bearings on which the eccentric bearings are supported, and a pair of frameless motors directly connected to the eccentric bearings in order to effect the rotation thereof through closed loop feedback control, in order to facilitate the automatic and accurate control of pressure level and uniformity along the nip of a printing press.

Systems and methods for allowing existing rotary printing press units to produce smaller pages at a faster rate of speed without having to replace the press unit. Specifically, the systems and methods relate to retrofitting an existing press unit to produce three pages of material in each full rotation instead of the traditional two pages.

Examples include a sheet processing machine to which a transport path is assigned for transporting sheets. The sheet processing machine includes an application device with an application point for applying material to the sheets. A cooling device including a cooling cylinder is arranged along the transport path, downstream from the application point. An inspection transport body is arranged along the transport path, downstream from the cooling cylinder, and has a sensor device of an inspection unit aligned therewith. Examples further include a sheet-fed printing machine with a simultaneous double printing unit and an application point. A curing device with an LED UV radiation source is arranged downstream from the application point and includes two curing units for drying two opposite sides of sheets. A cooling device of the curing device includes a cooling element with a line system, and the cooling section is arranged downstream from the curing section.
