ABSTRACT:
A shingling device for use in a mail document sorting apparatus includes a first conveyor belt for receiving a vertical stack of sorted documents. A guide element is oblique to the conveyor belt for shifting the moving vertical stack into a shifted oblique stack and defines a gap between the belt and the guide element to enable passage of documents from the lower portion of the stack. A rotatable roller is disposed adjacent and downstream from the guide element and has a lower surface partially obstructing the gap. The roller rotates opposite to movement of the first conveyor belt for shingling documents passing through the gap. A second conveyor belt cooperates with the first conveyor belt to confine shingled documents advancing on the first belt, and cooperates with the roller so that the second belt has a longitudinal velocity substantially equal to the tangential velocity of the roller.
