Abstract
A method and apparatus is provided for processing printed products such as newspapers, magazines or parts thereof in which the printed products are transported by controllable grippers of a conveying device wherein the printed product is held at a first edge which runs transversely to the conveying direction. The printed products are conveyed at a set conveying speed. The grippers are at least partially opened to displace the printed products in the mouth of the grippers. The printed products are then displaced in the mouth of the grippers until the second edge (which is opposite the first edge) is brought to rest on a straightening mechanism. The straightening mechanism is driven substantially in the conveying direction. The grippers are then closed to continue transporting the printed products. If the second edge of the printed products leads relative to the first edge, the straightening mechanism is driven at a lower speed than the conveying speed. If the second edge trails relative to the first edge, the straightening mechanism are driven at a higher speed than the conveying speed. Thus, the printed products are thrust towards the interior of the mouth of the grippers by the straightening mechanism before the grippers are closed.
