Abstract
Apparatus for alternately withdrawing lowermost sheets from stacks of sheets in two magazines has a frame which is reciprocable below the magazines along a horizontal path between two end positions and carries a main support, two auxiliary supports which flank the main support, and a suction wheel between the main support and each auxiliary support. The suction wheels are driven in phase with the movement of the frame whereby the wheels turn clockwise while the frame moves in one direction and anticlockwise while the frame moves in the opposite direction. Two toothed belts have end portions which are anchored in a tensioning device between the magazines, and the belts are trained over pulleys of the suction wheels and pulleys of rollers constituting the main support. One suction wheel attracts one edge portion of the lowermost sheet in one of the magazines, the main support is located below such lowermost sheet, and one auxiliary support is located below the lowermost sheet in the other magazine when the frame assumes one of its end positions. When the frame thereupon moves toward the other end position, the one wheel peels the lowermost sheet off the adjacent sheet while the main support moves below the lowermost sheet in the other magazine and the other auxiliary support moves below the fresh lowermost sheet in the one magazine.
