A method and system for sheet accumulating wherein a web of material is cut into groups of cut sheets and a right-angle transport device is used to collate the cut sheets into packets. Because the cut sheets in each packet are moved into and out of the right-angle transport device in separate paths with different pathlengths, the cut sheets overlap with each other by an overlapped amount as they exit the right-angle transport device. A path deflector having a curved path is used in at least one of the paths in order to reduce the pathlength difference, thereby increasing the overlapped amount.
