ABSTRACT OF THE DISCLOSURE The specification describes a device used in rotary printing machines for adjusting lateral register through axial displacement of the plate cylinder and for adjusting circumferential register by axial displacement of a helical drive gear of the plate cylinder. The device includes adjusting elements which act concentrically on the plate cylinder or on its drive gear. Each cylinder bearing is provided with a sliding bush connected to a toothed rim, which is adjustable by means of a screwthread on the cylinder bearing, which in turn is engaged by a worm spindle. The sliding bush in the cylinder for lateral register adjustment bears through a thrust bearing against a disc fastened on the cylinder journal. The sliding bush of the other cylinder bearing for circumferential register adjustment, bears through a thrust bearing against the helical drive gear, which is mounted for sliding on the cylinder journal and is supported by means of compression springs against a driver disc which is fastened on the cylinder journal.
