摘要： To permit relative angular shifting of transmission of rotation between the first gear (1) and a second gear (2), to thereby control the register of a cylinder coupled to the second gear (2) with respect to printing cylinders coupled to the first gear, a third gear (3) is drivingly connected between the first gear (1) and the second gear. The third gear is journalled to rotate about an eccentric portion (6) of a shaft element (9), the shaft element 9 being secured for rocking movement about a central axis (10), from which the eccentric axis (11) is offset. The central axis (10) of the shaft element (9, 6) and the centers of rotation (12, 13) of the first and second gears, respectively, are positioned on a theoretical plane, or line (16) and when the eccentric axis (11) is also located on this theoretical line (16) a normal position is defined. By rocking the shaft element (9, 6) out of the normal position, the engagement ( 73) of the third gear with the pitch circle of the first gear is shifted away from the central axis (10) and, further, the engagement point (74) of the third gear with the pitch circle of the second gear (2) is shifted closer to the central axis, thereby causing an angular shift of the second gear with respect to the first gear. The shift is usually only a few degrees and can be controlled, in either direction, by an operating lever (20) which can be positioned manually or by a servo motor, to retain the third gear in the normal position, or shift the third gear out of the normal position for register adjustment.
