Abstract
To provide a clean operator side (I) of a printing machine, the circumferential and lateral register adjustment of a plate cylinder (20) is located on the machine or drive side (II) of the machine and is formed by a special gearing arrangement; a first gear (12) which is rotatable on an axially shiftable stub shaft (19) of the plate cylinder by being positioned on a bearing thereof, is driven from a second gear (9) which may also drive an offset blanket cylinder (18). The first gear is in meshing engagement with a dual gear, having third and fourth gearings (16, 15), the first, second and third gears being spiral or inclined, and the fourth gear (15), which meshes with an axial fixed fifth gear (13) splined to the shaft fo the cylinder (19), is likewise formed with axial teeth. The combined third and fourth gears can be shifted axially, thus causing rotation of the fourth gear by the "thread" type engagement of the third gear with the first gear, which rotation is transferred to the fifth gear and hence to the plate cylinder; in addition, the axial position of the plate cylinder is independently adjustable by a spindle (29) moving the stub shaft without transmitting rotation theret…
