The invention relates to a positioning device for positioning at least two cylinders of a printing group of a printing machine. Said positioning device comprises at least one rail arrangement, and the rail arrangement comprises at least one rail and at least two carriages. Respectively one bearing connected to a journal of at least one of the at least two cylinders is arranged on each of the at least two carriages and the at least two carriages can be moved along the at least one rail and can be fixed in pre-determinable positions along the rail arrangement. The carriages can be moved and/or positioned along the rail arrangement by means of a drive selectively acting on at least one of the carriages, and/or a number of fixing elements is arranged at least along the at least one rail. The invention also relates to a method for positioning cylinders in a printing group of a printing machine.

The invention relates to a bearing receptacle of a bearing of a cylinder journal of a cylinder of a printing machine, wherein the bearing receptacle comprises at least two retractable bearing shells and wherein one of the retractable bearing shells is pivotally disposed relative to the other retractable bearing shell. A drive for pivoting said one retractable bearing shell is connected to the retractable bearing shell by means of a connection. The bearing receptacle is designed to be locked and unlocked by means of a different drive, said the bearing receptacle comprising a pivotable retaining clip designed for locking the bearing receptacle. The bearing receptacle comprises a pivotable actuating lever interacting with the retaining clip, wherein the actuating lever is pivotally disposed by means of the other drive and independent of the retractable bearing shell. A spring is disposed pressing the retaining clip in an unlocking position. The invention further relates to a method for closing and locking a bearing receptacle of a bearing of a cylinder journal of a cylinder of a printing machine, wherein the bearing receptacle is closed by means of a drive and wherein subsequently a retaining clip is pivoted into a position in which said clip locks the bearing receptacle. The retaining clip is pivoted by an actuating lever, said actuating lever pivoting the retaining clip against a spring force at least during a part of the pivoting motion.

The invention relates to a rotary printing machine having a printing mechanism, which is assigned at least one cylinder and which has at least two stores that are coupled to a guide system and can each be moved relative to the rotary printing machine and relative to one another, each one of said stores being able to be positioned in a defined transfer position and having at least one receiving means for receiving the at least one cylinder, wherein the printing mechanism has a movable handling means, which is assigned permanently to the respective store and by means of which the at least one cylinder, held in a positionally fixed manner to cylinder receptacles of said handling means, can be transferred between an installation position in at least one storage receptacle of the printing mechanism and a supply position in a receiving means of a store, and wherein the at least two movable stores are each arranged such that said stores can be moved along the guide system at least by means of one component in the vertical direction and at least by means of one component in an axial direction. The invention further relates to a method for replacing at least one first cylinder of a rotary printing machine.

The invention relates to a coupling device of a cylinder (01; 03) of a printing machine, said coupling device comprising a coupling body (603) that, in the coupled operating state, is connected to the cylinder (01; 03) in a non-positive and/or positive but detachable manner, and is also connected non-positively and/or positively, in the coupled state, to a rotatable and/or rotating component (611) of a drive (16) associated with the cylinder (01; 03). In the uncoupled operating state, the coupling body (603) is connected neither to the cylinder (01; 03) nor the drive (16), neither non-positively nor positively, in terms of rotational movements about a rotational axis (13; 14) of the cylinder (01; 03). In at least the coupled and uncoupled operating state, a housing (619) of the drive (16) is rigidly connected to a bearing receiver (32) in such a way that they are in the same relative spatial arrangement in relation to each other, said bearing receiver being able to receive and/or receiving a journal (17) of the cylinder (01; 03). The invention also relates to a method for coupling a cylinder (01; 03) of a printing machine to a drive (16) of the cylinder (01; 03).
