Abstract
To adjust the axial spreading movement of distributing rollers (30) in rotary printing presses, at least one eccentric stud (18) is mounted which is rotatable around its axis of rotation (19) in a rotatably drivable housing (3). The housing rotates around the axis of rotation (9) which is located at a distance (a) from the axis of rotation of the eccentric stud. The eccentric stud (18) has an eccentric pin (20), which is arranged at least at one of its ends and is located at the same distance (a) from the axis of rotation (19) of the eccentric stud (18). The eccentric stud (18) is rotatable via a sleeve (10) and via the planetary gear (16), i.e., the distance of the eccentric pin (20) from the axis of rotation (9) can be changed. The eccentric pin (20) transforms its rotary movement via a sliding block (29) into a reciprocating movement, with which the distributing roller (30) is axially driven.
