ABSTRACT:
A mechanism for adjusting the circumferential position of a printing cylinder includes first and second meshing helical gears. The helical gears are supported coaxially of the printing cylinder. A first one of the helical gears is fixed to the printing cylinder to rotate with the cylinder. The other of the helical gears is supported for movement axially relative to the first helical gear to effect a camming action therebetween which rotates the first helical gear and thus rotates the cylinder. However, upon axial adjustment of the cylinder, both of the helical gears move simultaneously axially with the cylinder.
