The invention relates to a printing machine provided with a control panel for the control thereof and a side which is oriented away from the control side. Said printing machine comprises a printing unit provided with at least one pair of cylinders made of forming and transmission cylinders which are mechanically coupled to each other by means of a drive connection and are rotationally driven by a drive motor which is mechanically independent from other printing units. The drive motor and the drive connection are arranged on the control side of the printing unit.

The invention relates to a printing unit comprising a pair of cylinders made up of a form cylinder and a transfer cylinder, in addition to a third cylinder, which forms a printing site with the transfer cylinder. The form cylinder and the transfer cylinder are coupled together in a fixed manner, forming a drive system, which is driven by a common drive motor during the printing process. Power is transmitted from the transfer cylinder of the pair to the form cylinder of the pair. The drive system of the pair and the drive of the third cylinder are coupled to one another in a mechanical manner by means of a coupling, so that they can be selectively coupled or decoupled.

The invention relates to a device for axially fixing a rotational solid between opposite frame walls, said device comprising a retainer arranged in a rotationally fixed manner on one of the frame walls. One end of the rotational solid to be axially fixed is rotatably retained in said retainer, wherein a plurality of rollers is arranged along a first circumferential line of the retainer. Each of said rollers is eccentrically mounted, wherein respective lateral faces of said rollers can be placed against a mounting element connected to the frame wall. The retainer is arranged supported by an abutment against the mounting element parallel to the axis of rotation of the rotational solid, wherein the rotational solid can be axially fixed by clamping the mounting element between the abutment of the retainer and the respective lateral faces of the rollers placed against the mounting element. The invention also relates to a method for axially fixing a rotational solid arranged between opposite frame walls, in which one end of the rotational solid is held on one of the frame walls by a retainer, wherein first rollers arranged on the retainer along a first circumferential line are placed against a mounting element connected to the frame wall, wherein said mounting element connected to the frame wall is clamped between respective lateral faces of the first rollers and an abutment supporting the retainer on the mounting element on the retainer, wherein the rotational solid is axially fixed by said clamping of the mounting element.

The invention relates to a printing group pertaining to a printing machine comprising at least three cylinders, i.e. a form cylinder, a transfer cylinder and a counter-pressure cylinder. Said transfer cylinder is positioned, on the front side, on two levers which can be pivoted about a pivoting axis, in order to be lowered or raised in relation to a counter-pressure cylinder. Said levers can be pivoted by at least one drive means which is embodied in the form of a pressurised cylinder acting on a moveable joint of an articulated lever mechanism, said mechanism being connected to the levers and to a rotational point fixed on the frame.

The invention relates to a printing unit (01, 46) comprising a pair (02) of cylinders made up of a form cylinder (03) and a transfer cylinder (04), in addition to a third cylinder (08, 09), which forms a printing site (11) with the transfer cylinder (04). The form cylinder (03) and the transfer cylinder (04) are coupled together in a fixed manner, forming a drive system (23, 58), which is driven by a common drive motor (06) during the printing process. Power is transmitted from the transfer cylinder (04) of the pair (02) to the form cylinder (03) of the pair (02). The drive system (23) of the pair (02) and the drive of the third cylinder (08, 09) are coupled to one another in a mechanical manner by means of a coupling (12), so that they can be selectively coupled or decoupled.

A cylinder of a printing press is supported by bearings in side frames of the printing press. An inner ring of a radial bearing serves a journal of the cylinder which is arranged directly over a bearing agent in an outer ring thus enabling a radial movement of the journal. The outer ring is mounted, either directly or indirectly in an opening of the side frame. The radial bearing is arranged in a region of the outer ring, as viewed in an axial direction of the cylinder, which protrudes out of a frame alignment of the side frame toward the side of the cylinder. The bearing agent which enables radial movement of the cylinder is also arranged in a region of the outer ring protruding out of the frame alignment of the side frame toward the side of the cylinder.

The invention relates to devices and methods for raising and/or lowering a lift by means of a pressure device comprising a roller. The roller is arranged on a cross-beam in such a manner that the roller can be selectively placed on and/or taken a cylinder or a lift arranged on the cylinder by a drive. The invention is characterised in that the pressure device or the cross-beam supporting the roller can be displaced together in such a manner that the distance of the roller from the cylinder can be selectively increased.
