The invention relates to a device for cutting through a web running to a driven winding roll and for fixing the following web beginning to a winding core or to a winding tube. Said device comprises a winding roller, which leads to the winding roll and against which a winding tube can be placed, a blade that cuts through the web, and comprises means for diverting the web beginning from the winding roller to the driven winding tube. In order to permit, in a simple manner, a web beginning that is cut free to be wound onto a winding tube without applying adhesive, deflection rollers, which are mounted on supports like a pair of tongs, can be moved into the roller gaps between the winding roller and the winding tube that is placed against the same. At least one endless belt runs over said deflection rollers and, as the deflection rollers are moved into the roller gaps (10), it encompasses part of the winding tube facing away from the winding roller. The winding roller is provided with a cutting blade that can be extended out of a slot located on a surface line and, in the direction of rotation behind the cutting blade, is provided with a device, which introduces the web beginning formed by the separated section into the gap located between the winding tube and the belt that runs over the deflection rollers and onto the winding tube.

The invention relates to a changing station for sleeves (12, 15) of a printing press (1), comprising a magazine (17) with at least one receiving device (18) for sleeves (12, 15) which (8) can be vertically displaced. At least one further displacement device (21) for displacing the magazine (17) is provided in the horizontal direction and allows the magazine (17) to be displaced in a horizontal (x) and vertical (y) plane along the printing press (1).

The invention relates to a system for exchanging sleeves (6, 6a), (6, 6a) that can be pushed onto the mandrels (5, 5a) of ink transfer rollers (4) of at least one printing press (1). Said system comprises a storage device, in which sleeves (6, 6a) (6, 6a) that are not required for the current print job can be stored and/or transport means (8, 9) for transporting several sleeves (6, 6a) (6, 6a) to the printing press (1). The invention is characterised by the means for transferring sleeves, said means transporting the sleeves (6, 6a) between the storage device and/or the transport means (8, 9) and the mandrels (5, 5a) of the ink transfer rollers (4) in the printing press or presses (1) and/or between the storage device and the transport means (8, 9).

摘要:
The invention relates to a method for replacing printing sleeves (7) in a printing press (1), according to which printing sleeves (7) that are not used for the current printing process are stored in at least one storage device while at least one conveying apparatus (13) that comprises printing sleeve-receiving devices (14) conveys the printing sleeves (7) between the storage device and the printing press (1) in order for the replacement to take place, the printing sleeve-receiving devices (14) being able to bring the printing sleeves (7) into a position that is suitable for replacing the printing sleeves (7). The invention is characterized in that the arrangement of the printing sleeves (7) in the conveying apparatus (13) is determined by an arithmetic and control unit (19) which knows the set-point positions of the printing sleeves in the printing press during the next print job. The arithmetic and control unit (19) establishes the arrangement of the printing sleeves (7) in such a way that at least one printing sleeve-receiving device (14) remains free in the conveying apparatus (13).
