ABSTRACT OF THE DISCLOSURE To permit radial removal of a cylinder, roller or similar element in a printing machine from between the side walls (1) thereof, the cylinder or roller (9) is formed with two stub shafts (8) coupled by separable half-shells (5, 6) to the ends of shaft elements (3) passing through the side wall (1) of the printing machine. One of said shaft elements can be coupled to a drive gear (4). In accordance with the invention, and to permit rolling off of the stub shaft (8) of the cylinder over the half-shell, the separating surfaces (10, 11, 12, 13) between the half- shells are formed to extend essentially tangentially with respect to the part-circular clamping surfaces (14, 15) which clamp the stub shaft to the shafts (3) passing through the side wall, one of the half-shells being secured to the shaft elements. Preferably, a locating abutment or notch (17) is formed on the half-shell (6) secured to the machine shaft (3) to permit placement of a locating projection (18) on a roll-out rail (19) against the half shell so that, upon removal of the other half-shell (7), the cylinder can be rolled off on the rail after passing over the separating surface.
