ABSTRACT:
An apparatus for transporting paper sheet material in signature form to an off-line receiving station. The apparatus includes a horizontal frame connected with a stacker at one end and registering with the receiving station at the other end. A conveyor mounted on the frame comprises a plurality of horizontally disposed supported belts which receive signatures from the stacker. The belts are spaced apart to form gaps therebetween. A plurality of tracks are mounted horizontally in the frame and extend from the conveyor to the crosspiece. The tracks are supported and can be raised or lowered. A shuttle carriage having a plurality of connected vertical segments rides on the tracks. The segments can be lifted or lowered. The segments of the carriage are aligned with the gaps between the endless belts so that the carriage can ride freely along the frame. A plurality of horizontally disposed rollers are also mounted on the frame above the tracks which are in longitudinal alignment with the conveyor belts. The carriage further includes an upright member extending above each carriage segment having a vertically disposed roller. The carriage may be provided with a pivotably mounted latch to releasably retain the carriage at the crosspiece and the apparatus may further include a counterweight system for biasing the carriage movement toward the conveyor.
