ABSTRACT:
An improved sheet material handling apparatus includes a pair of saddle conveyors. An extractor drum sequentially grips folded edge portions of signatures in hoppers and moves the signatures along an arcuate path. During rotation of the extractor drum to move the signatures along the arcuate path, a first signature engages a first stop member and is transferred to a first saddle conveyor. The first stop member is then retracted and the next signature moves past the first stop member into engagement with a second stop member. The second signatures is then transferred to a second saddle conveyor. A single stitcher assembly is provided to stitch signatures in first and second spaced apart streams of signatures being conveyed by the two saddle conveyors. In addition, a single trimmer assembly is provided to trim the signatures while maintaining the signatures in the first and second spaced apart streams of signatures.
