A device for guiding a tympan on a cylinder of a printing machine by means of at least one roller element is disclosed. A support with a first end and a second end is provided. The first end of the support is connected to a cross-piece, running along the cylinder and at least one roller element is arranged on the second end of the support. The support is an elastically flexible body. An adjuster acting on the support is arranged between the cross-piece and the support and on operation of the adjuster the same moves the roller element towards the cylinder or away from the cylinder as a result of an elastic flexing of the support.

During mounting and dismounting of blankets (2) on cylinders (1), rollers (3) are pressed against the cylinder in order to ensure uniform winding and unwinding. It is necessary to apply a uniform positioning pressure for a low control and driving expenditure. According to the invention, such a device for pressing blankets against cylinders is obtained by applying simultaneously several movable rollers (3, 29), independently from each other, by means of a single actuator (4). According to a particular embodiment of the invention, first and second rollers can be actuated for respectively mounting and dismounting the blanket. The assembly can be protected against contamination by moving a protection (47) by means of the same actuator. A stop is used for the correct positioning of the plate at the forward end.

The invention relates to devices for storing a blanket (01, 36, 37) to be supplied to a cylinder (06, 31, 33) of a printing machine. According to the invention, a plurality of blankets which are to be adjacently applied to the cylinder in the axial direction thereof are stored next to each other. Said blankets are stored vertically above a supporting surface, in at least two vertically offset planes. The offset planes form a first storage position for the blankets, and the supporting surface forms a second storage position once at least one of the blankets stored in the offset planes has been placed thereon.

The invention relates to a rotative body of a printing press and to a method for producing said body. The rotative body (01) comprises a base body (28) with a surface (29). According to said method, an external body (38) comprising at least one slot or groove that forms a flow channel (37) is placed on the surface (29) of the base body (28) and a covering (36) that covers the flow channel is placed on the external body (38).

The invention relates to a mechanism for mounting a dressing on the cylinder of a printing press. The inventive mechanism is fitted with at least one stop which is effective in an axial direction of said cylinder. The stop allows the cylinder dressing to be arranged on the cylinder with precision in an axial direction thereto. The stop is disposed outside the cylinder.

The invention relates to a cylinder of a printing unit of a rotary offset printing machine. Said cylinder has a periphery and a length in an axial direction, whereby the lateral surface (13) of the cylinder is subdivided, over the length thereof, into at least three sections (A, B, C) that are lined up next to one another. Said lateral surface has, in at least three sections, at least one slot-shaped opening (14), whereby at least two openings arranged in two different sections are offset from one another with regard to the periphery (U) of the cylinder. This cylinder is preferably intended for use in a cylinder pair consisting of a 6/2 printing cylinder (01a) and of a transfer cylinder (01b).
