ABSTRACT:
A rotatable printing machine includes a horizontal exchangeable cylinder which is held between two sidewalls of a machine frame by a holding and driving arrangement which enables disengagement. To remove the cylinder, a carriage arrangement is positioned in the frame and can include a movable trolley for receiving the cylinder and sliding it in a horizontal plane onto a hand cart. One embodiment includes a movable table for raising and lowering the cylinder from the path of the trolley to the operating position. Another embodiment positions rails for the trolley immediately underneath the operating position of the cylinder and includes an arrangement for raising and lowering supports for the cylinder relative to the cylinder. A third embodiment includes a fixed track mounted immediately adjacent the cylinder and utilizing position adjustment means for the drives of the cylinder to lower the cylinder onto the track.
