Abstract
An apparatus for sequentially stitching groups of sheets includes a reject assembly which directs groups of sheets containing either more or less than a predetermined number of sheets to a receiving station without being stitched. If a desired number of sheets is in a group, the group will move through the reject station to a stitching station and then through a folding apparatus at one of two discharge stations. The reject assembly includes a ramp which is movable between a retracted position aligned with a main support surface and an extended position projecting upwardly from the main support surface to a reject conveyor. A main conveyor pushes a group of sheets containing more or less than a predetermined number of sheets up the ramp to a reject conveyor which conducts the groups of sheets to a receiving station. To facilitate setting up of the apparatus, the reject assembly is operated to either reject all of the groups of sheets or none of the groups of sheets depending upon whether or not it is desired to move the groups of sheets through the stitching station.
