Abstract
A device for separating a printed product into two groups of pages wherein the product is held between two faces of a pocket and an element presses against the fold to cause the product to bow outwardly and form an opening. A preopener is inserted into the opening and moved toward the free edge. Thereafter, grippers hold the corners to prevent curling and an opener moves across the width of the product where the opposite corners are held.
