- the printing forms can be arranged with their ends offset in the circumferential direction from one another in different channels or the forme cylinder can have at least two printing forms or several printing forms arranged one behind the other in the axial direction, in the case of several printing forms arranged over the entire circumference, these with their ends can also be arranged alternately offset in the circumferential direction.
- DE 2220652 A1 describes a device for attaching flexible printing plates to the plate cylinder of a rotary printing press, the device having pairs of clamping jaws arranged on the same axis and pivotable about an axis parallel to the cylinder axis and extending over the entire length of the cylinder in a cylinder channel are arranged in the cylinder body.
- a pair of clamping jaws consists of a clamping jaw and one Clamping jaw, with both the clamping jaw and the clamping jaw interacting with it being pivotably mounted about an axis parallel to the cylinder axis and being operable from the end face of the cylinder.
- a short pair of clamping jaws is to be arranged as an extension piece between two adjacent pairs of clamping jaws such that it is coupled in the cylinder body with the adjacent pairs of clamping jaws and thus pivoted in the same way as the pairs of clamping jaws can.
- each cylinder channel two coaxially arranged connecting shafts are provided, which can be rigidly connected with a pair of clamping jaws arranged in one half of the cylinder length and make a torque transferable from the end of the cylinder belonging to the other half to the pair of clamping jaws connected to the connecting shafts.
- the connecting shafts are therefore pivoted in the cylinder channel as well as the pair of clamping jaws connected to them.
- a pair of cylinders of a rotary printing press with a 6/2-plate cylinder and a blanket cylinder is known, the plate plate having the middle plate set to the two outer plate plate sets and the plate blanket the middle blanket compared to the two-sided outer blankets by a deliberate 90 ° different angles are arranged offset.
- the non-angled ends of the elevators resting on the respective cylinder are held by holding means which can be moved in wide cylinder pits. Opposing ends of elevators form between them a gap which extends across the width of these elevators.
- a device for tensioning and / or clamping flexible plates with folded-in hanging legs which is integrated into one Fastening slot of a cylinder carrying the plates protrude, the fastening slot being connected in the radial direction of the cylinder to an axially parallel cylinder groove, wherein a base body which is open in the direction of the fastening slot is arranged in the cylinder groove, tensioning and / or clamping elements being movable within the interior of the base body are provided, wherein the base body can consist of several shorter base bodies that can be coupled together.
- the base body or bodies arranged in a row in the cylinder pit are connected to one another in a rotationally fixed manner, for example by means of a toothing, wherein a first and a last of the base bodies are each connected in a rotationally fixed manner to an end coupling piece which, with its parts covering the cylinder pit, on the flanks of the Cylinder is fastened for example by screwing.
- a cylinder of a web-fed rotary printing press is known from DE 199 61 574 A1, the lateral surface of the cylinder being divided into sections lined up along its length and an opening being provided in each section.
- This type of cylinder is not suitable for the arrangement of several elevators on the outer surface of the cylinder along its circumference.
- Such a single circumferential cylinder is also known from JP 10-071 694 A, the forme cylinder and the transfer cylinder being arranged in the printing unit in such a way that an open section of the forme cylinder rolls on a closed section of the transfer cylinder and vice versa.
- DE 198 54495 A1 discloses a printing group cylinder with a channel with alternatingly arranged and closed areas on the lateral surface, with tabs of a printing form to be mounted on the printing group cylinder engaging in the open areas.

With one of an end face of the cylinder 01a; 01b torque exerted on the spindle can one or more holding devices in the channels 11 ';11; 12 are operated.
- a spindle can extend from one end of the cylinder 01a; 01b in channel 11 ';11; 12 by a on the edge of the cylinder 01; 01a; 01b arranged section A or C (Fig. 2), in the relevant channel 11 ';11; 12 no opening 14 to the outer surface 13 of the cylinder 01a; Olb has, extend and a holding device in section B, which in the channel 11 ';11; 12 to the outer surface 13 of the cylinder 01a; 01b has an opening 14, actuate, with this section B both the channel 11 ';11; 12 as well as that in this channel 11 ';11; 12 arranged adjusting means 23 or the spindle end.
- the channel 11 'or the channels 11; 12 in cylinder 01; 01a; 01b are configured whether they are continuous from one end to the other of the cylinder 01; 01a; 01b are or only in the respective sections A; B; C; D are designed as sections, according to the solution proposed here for a cylinder 01; 01 a; 01 b with the circumference U and the length L, the outer surface 13 of the cylinder 01; 01a; 01b over the length L into at least three sections A; B; C; D is divided that the outer surface 13 in at least three sections A; B; C; D each has at least one slot-shaped opening 14, at least two openings (14) of a section A; B; C; D to the openings 14 of another section A; B; C; D with respect to the circumference U of the cylinder 01; 01a; 01b are arranged offset to one another.
- Each opening 14 opens at least a portion of one located under the outer surface 13 of the cylinder 01; 01a; 01b extending channel 11 ';11; 12th
- B. has at least two elevators 02m to 02o, wherein at least two of the elevators 02a to 02I arranged on the forme cylinder 01a in its axial direction are arranged offset from one another along its circumference U.
- the forme cylinder 01a preferably has axially at least four elevators 02a to 02I, the elevators 02a to 02!
- the forme cylinder 01a can have axially six elevators 02a to 02I, which are arranged in pairs on the forme cylinder 01a in the axial direction thereof.
- the elevators 02m to 02o of the transfer cylinder 1b are preferably as long as two elevators 02a to 02I of the forme cylinder 01a in relation to its circumference U, so that in this printing unit a double-circumference forme cylinder Ola and a single-circumference transfer cylinder 1b interact and roll on each other.
- this printing unit As described above, it is advantageous to design this printing unit as a 9-cylinder satellite printing unit. Because a printing unit with cylinders of great length, z. B. with a length of up to 2400 mm, the printing unit having a forme cylinder, which preferably prints six newspaper pages next to each other in its axial direction, and has a corresponding cylinder interacting with the forme cylinder, tends to be particularly annoying at high rotational speeds, the printing quality impairing bending vibrations, which are exacerbated by the channel blow between the forme cylinder and the transfer cylinder.
- each transfer cylinder can be supported on a central impression cylinder, the impression cylinder in turn moving from one to the first Transfer cylinder is diametrically arranged second transfer cylinder is supported.
- the impression cylinder usually has a smooth, closed outer surface, which supports the transfer cylinder over the entire surface.
