ABSTRACT:
To permit placement of an exchange or replacement cylinder, such as an Anilox inker roller between side walls (1) of a printing machine which is formed with openings to receive rollers of an inker for a raised letter, or offset printing system, and positioned such that the larger diameter Anilox roller will not fit into an existing opening, an arrangement is provided to relocate the center of rotation (7a) of the Anilox roller (7) with respect to the center (6a) of an existing opening which includes an axially (15) journaled in the existing opening and rotating about the original bearing axis (6a), the axially shaft having two spur gears (16, 17) at its ends, projecting, respectively, inwardly and outwardly of the side wall (1). The spur gears are engaged by inwardly geared ring gears (19, 22) respectively, one ring gear (19) being located outside of the side walls and journaled for rotation about the replacement axis (7a) by a flanged bearing bolt (18) secured the side wall, for example, and preferably including an outer gear (19a) to receive drive power. A, preferably similar, inwardly geared ring gear (22) meshes with the inner spur gear (16), the inner ring gear being secured to a stub shaft (23) on the Anilox roller, rotatable about the replacement axis of rotation (7a), and retained in place by bearing (24) located within the bearing housing (25) which, preferably, can be rocked about the original bearing axis (6a), by being connected over bearings (27) with the side wall (1) of the machine, so that the Anilox roller (7) can be rocked in and out of engagement with an existing plate cylinder.
