Abstract
Device for adjusting circumferential and lateral register in a rotary printing machine having support frames at opposite drive and operating sides thereof and a plate cylinder drivable by a spur gear at the drive side, including first and second adjusting members on the operating side for turning the plate cylinder radially relative to the spur gear for driving the plate cylinder for circumferential register adjustment and for axially displacing the plate cylinder for lateral register adjustment. An adjusting spindle which extends axially through a bore formed in the plate cylinder is coupled at the operating side to the first adjusting member and is connected, at the drive side, to a threaded member. A thrust bearing is operatively associated with the threaded member and with the spur gear driving the plate cylinder. The spur gear is carried by a coupling and is displaceable axially thereon relative to the plate cylinder by the first adjusting member through the adjusting spindle, the threaded member and the thrust bearing, a rotatable bushing coupled to the second adjusting member at the operating side, a device for axially displacing the plate cylinder together with the adjustin…
