Abstract
A reject control system is used in a collator having a plurality of hoppers for feeding a plurality of signatures to collating spaces along a collating conveyor movable past the hoppers. Each collating space is divided into a plurality of segments in which at least one segment is associated with a dead zone of the collating space. A shift register has a plurality of adjacent bits. Each bit is associated with a segment of a particular collating space. The setting of a bit associated with a segment other than a segment corresponding to the dead zone of a collating space is indicative of a misfeed condition in the collating space. Information is shifted between adjacent bits in the incremental shift register during operation of the collator.
