In order to be able to eliminate a mechanical caliper, a bindery line has a plurality of signature feeders or packer boxes each of which is operable to feed a signature therefrom. A collating conveyor passes by each of the signature feeders or packer boxes along a signature conveying path so as to be operable to receive signatures from the signature feeders or packer boxes in collated form for forming a book. A book finishing section is downstream of the signature feeders or packer boxes for forming the book from the signatures received in collated order after the collating conveyor has passed by each of the signature feeders or packer boxes in travel along the signature conveying path. With this arrangement, the invention utilizes detectors for detecting a missing signature, an incorrect signature, a double signature, a conveyor jam, a hanging book, and a long book.
