ABSTRACT:
An impression cylinder provided with a replaceable sleevelike impression cylinder shell is movably and releasably mounted in a printing press by a bearing in such a manner that the impression cylinder adjacent to its one stub shaft is adapted to protrude freely from the machine frame and permit replacement of the impression cylinder shell. In order to permit a particularly simple replacement of the impression cylinder shell, the bearings are hinged bearings having bearing shell sections which can be swung off to a position in which they permit the impression cylinder to be swung out in a horizontal plane. The impression cylinder is provided at one end with a stub shaft, which extends beyond the associated hinged bearing and which at the top of its end portion is supportedd by a supporting shell section, which is axially immovably mounted in the machine frame for rotation about a vertical axis. A movable horizontal supporting rail or slideway is provided, which is movable from below into engagement with the impression cylinder, or with a shaft portion connected to the cylinder, at a location between the bearings. The rail or slideway is adapted to be fixed in position, so that the impression cylinder which is held between the supporting shell section and the supporting rail can be pivotally moved out of the opened hinged bearings about the vertical pivot for the supporting shell section.
