ABSTRACT:
In an imbricated formation delivered by an infeed device in each case two printed products lie in pairs upon one another and, viewed in a predetermined product conveying direction, bear upon the upstream or trailing printed product pair. A suction roll is arranged downstream of the infeed device which causes the current lower printed product to be downwardly bent in a direction transverse to a product conveying plane. The leading edges of the printed products are introduced in such separated or fanned apart condition into a respective gripper, engaged by such respective gripper and outfed in a further predetermined conveying direction. The spacing between neighboring grippers is minimal at a product take-over region, so that when the grippers are open in each instance a leading gripper finger of a trailing gripper bears against a trailing gripper finger of the neighboring leading gripper.
