Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
129 words
A reject control register for use 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 being divided into a plurality of segments in which at least one segment corresponds to a dead zone of the collating space, said reject control system comprising: a shift register having a plurality of adjacent bits, each bit being 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 being indicative of a misfeed condition in the particular collating space; and means for shifting information between adjacent bits in said incremental shift register during operation of the collator.
Claim 2
Dependent Claim
129 words
A reject control register for use 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 being divided into a plurality of segments in which at least one segment corresponds to a dead zone of the collating space, said reject control system comprising: a shift register having a plurality of adjacent bits, each bit being 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 being indicative of a misfeed condition in the particular collating space; and means for shifting information between adjacent bits in said incremental shift register during operation of the collator.
Claim 3
Dependent Claim
22 words
The reject control system of claim 1 wherein each collating space has twelve bits associated therewith at a given moment in time.
Claim 4
Dependent Claim
27 words
The reject control system of claim 2 wherein four of the twelve bits associated with each collating space correspond to the dead zone of the collating space.
Claim 5
Dependent Claim
28 words
The reject control system of claim 1 wherein said means for shifting information provides a master sync control signal for shifting the bits in said incremental shift register.
Claim 6
Dependent Claim
39 words
The reject control system of claim 1 wherein at least one bit is associated with the dead zone of each collating space and at least one bit is associated with other that the dead zone of the collating space.
