ABSTRACT:
A sheet feeding arrangement with a side pulling mark for subsequent sheet alignment, in which at least one pulling element actuated cyclically with the sheet feeder and moving back and forth transversely to the direction of sheet movement, grasps the sheet to be aligned and pushes it against a stop strip. The pulling element is in the form of a suction grip located beneath the sheet to be aligned. The suction grip is kept movable on a bearing member moving back and forth transversely to the sheet feeding direction. The bearing member has a stop located forward in the pull direction, and is assigned to the suction grip. The latter can be returned to its stop position after each deflection by a spring acting in the pull direction. This spring is adjustable, and the suction grip has a suction cup which is rotatable about its axis. The suction cup is also movable perpendicular to the plane of the sheet. The suction grip is pivotably mounted on the bearing member.
