Abstract

Device for skewed sheet correction in a feeder of a sheet-fed printing press having at least one sucker which is adjustable in height and is disposed on a driven movable sucker carrier for horizontally transporting and simultaneously aligning a sheet lifted from a sheet pile, a rocker arm mounted in a frame of the printing press, the sucker carrier being articulatingly connected to the rocker arm so as to be movable in a feeding direction of the sheet and swingably driven, and a cam guide which is adjustable in height, the sucker carrier being braced against the cam guide, includes another rocker arm adjustably supported in the press frame, the sucker carrier being spaced apart from the first-mentioned rocker arm in a direction transverse to the sheet feeding direction and being articulatingly connected to the other rocker arm.
