ABSTRACT:
A collating apparatus for assembling a magazine from a plurality of signatures has a conveyor movable successively through a plurality of signature feeding stations and includes feeder sensors for sensing malfunctions of each feeding station. A rejection station following the last signature feeding station rejects magazines for which any of the feeder sensors sensed a malfunction. Another sensor at an inspection station following the rejection station senses the presence or absence of a magazine and compares the results with a malfunction-data record to monitor the performance of the rejection station. After a predetermined number of magazines have been assembled, a test of the operability of all of the sensors is automatically conducted by inhibiting the feeding of signatures and detecting whether or not every sensor properly senses the intentionally produced fault.
