ABSTRACT:
Signatures of a book are identified with a binary coded indicia on the backbone. A signature verifier having a row of indicia sensors associated with the stack of signatures in the stream feeder of a gathering machine senses the coded indicia. In the event of an error, the verifier gives an alarm or stops the stream feeder. A book of plural signatures has a plurality of indicia on the backbone. A verifier has corresponding plural rows of sensors which detect the indicia and are sampled sequentially.
