摘要： An apparatus for attaching and detaching bearings comprises a stand which is arranged in a position where the bearing for the printing cylinder is attached to and detached from the hole on a frame in a printing press, and which is, also, arranged movably on the side face of the frame of the printing unit. To this stand, there are connected an actuator for extracting the bearing, and a member for extracting the bearing, which engages with the bearing. An apparatus is arranged in a printing press for horizontally holding the printing cylinder which is supported by the other bearing in a cantilever fashion when either one of the bearings supporting the shafts on both sides of the printing cylinder is removed. For this apparatus, a device is arranged for thirsting up the shaft of the printing cylinder, and two bearings are mounted in the bearing on the side where the printing cylinder is held in a cantilever fashion, and then, the interval between these bearings is widened. An apparatus is arranged for providing a connecting shaft penetratingly in the cylinder of the printing cylinder rotatively supported through a pair of eccentric bearings on the left- and right-hand sides between a pair of frames on the left- and right-hand sides of a printing press, and each of the eccentric bearings is connected to the connecting shaft.

摘要： A printing cylinder 20 has a length for mass printing and is used for an inking roller group for supplying printing ink, a plate cylinder having a printing plate, a blanket cylinder for printing with the ink transferred from the printing plate, etc. A ring groove 25 is dug at each end face of the printing cylinder 20 so as to open annularly and to have a depth of 1/4 to 1/3 of the length of the printing cylinder 20 in the axial direction of the printing cylinder. Deflection deformation caused on the outer circumference of the printing cylinder 20 can thereby be equalized at the central portion and both end portions of the printing cylinder 20. Axial directional changes in the pressing force caused by the deflection deformation can be reduced, and even with the elongated printing cylinder 20 of the same cylinder diameter as a conventional one, irregularities of inking in the axial direction of the printing cylinder 20 due to changes in the pressing force do not occur. Thus a high quality printing is maintained.
