Abstract

In a rotary printing machine, a register adjustment device for adjusting circumferential register and lateral register of a plate cylinder mounted for displacement in axial direction thereof and being connected to a device for displacing the plate cylinder in axial direction includes a double gear having first and second toothings thereon, one of the toothings having obliquely extending teeth and the other of the toothings having teeth extending in a direction differing from the direction in which the teeth of the one toothing extend, both the first and the second toothings being immovable relative to one another, the double gear being also mounted for displacement in axial direction thereof and being connected to a device for displacing the double gear; a drive gear meshing with the first toothing; and a further gear meshing with the second toothing, the further gear being connected with the plate cylinder and fixed thereto against relative rotation therewith and against relative displacement in axial direction thereof, the other toothing being formed of straight teeth.
