  • Patent number: 5112036
    Abstract: A device for opening a printed product having three open edges and one folded edge having a pocket which can close to hold the product. A splitter enters the product from one side and divides the pages into approximately equal bundles. A pair of grippers then holds the corners while a spiral enters the opening between the bundles and carries it to the opposite side. At that point, a second pair of grippers holds the opposite corners to thereby hold the bundles against the walls of the pocket. The pocket opens and the product is ready to receive inserts.

  • Patent number: 5065994
    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.
