ABSTRACT:
An apparatus for compiling and processing a plurality of differently printed groups of sheets into collated sets is disclosed, and wherein each of the printed sheets has an indicium thereon at a predetermined location and with the predetermined location on the printed sheets for each group being different from the location of the indicium on the other group of sheets. Feeder structure is provided for sequentially depositing a sheet from each of the groups onto predetermined spaced locations of an advancing conveyor and sensors are mounted along the path of the feeder structure for detecting whether an indicium is present at the proper predetermined location on each of the withdrawn sheets, and such that the sensors are adapted to identify an improperly collated sheet as well as a missing sheet.
