Abstract
To permit re-sleeving or re-coating of circumferentially continuous printing cylinders, one of the side walls of the printing machine is formed with an opening which is closed off by two separable parts, which are movable towards and away from each other, the separable parts being formed with holes to receive stationary shafts for the respective cylinders. The stationary shafts have ball bearings thereon on which the cylinders are rotatably mounted, the shafts extending beyond bearings in a second side wall and being retained in bearings therein and, beyond the bearings, coupled to a counter holding arrangement so that, upon separation of the parts of the first side wall (1), the shafts come free, permitting access to the circumferences of the cylinders for re-coating or re-sleeving. The cylinders are coupled to drive gears therefor, which can be partly inclined to permit register adjustment and bearings or bearing bushings, eccentric with respect to the holding shafts, can be provided to permit engagement and disengagement of cylinders against each other.
