Abstract
Device for register correction and for compensating for distorted sheets in a pregripper of a feeder for a sheet-fed rotary printing press has a frame-fixed brace disposed on a pregripper shaft and located approximately centrally between end supports on a gripper bar, the gripper bar being supported rigid against torsion at opposite ends thereof on the pregripper shaft and being capable of executing swivelling movements in a sheet-feeding direction and in a direction opposite thereto, the frame-fixed brace serving for elastically bending the gripper bar in the sheet-feeding direction before the sheet is gripped by sheet grippers which are disposed side by side on the gripper bar and are swivellable about an axis of the pregripper shaft, the brace including a cam roller by which it runs onto an adjustable cam having a frame-fixed support, and an articulated joint with an eccentric element having a lever arm connected thereto for carrying the cam roller spaced from a center of the eccentric element.
