ABSTRACT:
A method and apparatus for opening folded sheets which are moved from a stack and by a gripper member to a location between two belts. The belts direct the folded sheets to a guide which causes the sheet to become unfolded and the guide then directs the sheet onto a gatherer or collector chain. A sheet opener can also be used for directing one flap of the folded sheet to the far side of the chain which is running at an acute angle with respect to the direction of movement of the unfolded sheet as it approaches the chain.
