ABSTRACT:
The invention relates to a device for the aligning of printing plates (78) on a printing plate cylinder (10) for a rotary printing press. At least one bore (16) extends through the printing plate cylinder (10) in an axial direction. A movable actuating shaft (26) is disposed in the bore (16). Located in the shaft (26) are a plurality of ring-shaped tensioning and adjustment elements which are spaced apart from one another. The adjustment elements (36) have movable aligning elements/register pins (56) arranged thereon. The invention is characterized in that, for at least one adjustment element (36), an eccentric pin (21) extends between the adjustment element (15) and the register pin (19). The eccentric pin (21) is rotatable to move the register pin (19) along the adjustment element (15).
