Abstract: Sorting apparatus has vertically adjustable sheet receiving and feeding vacuum chamber and traveling belt mechanism which directs successive sheets to a receiver having vacuum chamber and traveling belt conveyor mechanism for transporting sheets to or past vertically spaced trays. Fingers are shiftable to and from positions to deflect sheets from the transport conveyor and cause sheets to enter the trays. The receiving and feeding mechanism and the receiver are separable at the vertical plane of the fingers between the fingers and the vertically extended traveling belts.
