The invention relates to an arrangement for insertion into one end of a distribution cylinder in printing machines for converting the rapid rotational movement of the cylinder to a slow reciprocating cylinder movement. The other end of the distribution cylinder is journalled in a stationary shaft fixedly mounted in a printing machine frame. The inventive arrangement is mounted above the stationary shaft. The inventive arrangement includes a cylinder (2) which is intended to be fixed in the distribution cylinder. The cylinder (2) is journalled for rotation around the stationary hollow shaft (1). A camming groove element (8; 8A) is fixed axially on the stationary hollow shaft (1) and is journalled for centered rotation about the symmetry axis (24, 25) thereof. A runner-camming groove-unit (13, 9) the slow, relative rotation of the camming groove element to an axial reciprocating movement of the cylinder (2), therewith causing the distribution cylinder to move axially backwards-and-forwards. |
