FIELD: printing machines, in particular, printing machines with extending printing cylinder.
SUBSTANCE: printing machine for printing on corrugated carton and similar materials contains printing cylinder, provided with radial apertures for outlet of compressed air for ensuring possible mounting and removal of printing cartridge, on which printing block is mounted. Printing cylinder consists of fixed shaft, on which hermetically with possible sliding a moveable cylinder is mounted, which carries printing cartridge. Printing cylinder is supported on one end by detachable supporting means, providing for possible axial movement of moveable cylinder and contains means for axial movement of moveable cylinder between closed and extended position for replacement of cartridge, in which it protrudes from side part of the machine. Extension is performed by the same compressed air, which is used for replacement of printing cartridge.
EFFECT: simplified replacement of cartridge in devices with obstructed access to free end of cylinder, primarily in devices for processing corrugated carton.
