• a first transfer means for transferring the plurality of books to said gripper conveyor upstream of said repair loop section;
• and
• a second transfer means for transferring an out-of-sequence book to said gripper conveyor downstream of said repair loop section so that the books are in the predetermined sequence.

A method for forming a plurality of individual books in a predetermined sequence comprising the steps of:

• moving a plurality of spaced collating stations past a plurality of feeders;
• selectively feeding signatures to the spaced collating stations as the plurality of spaced collating stations move past the plurality of feeders to form the plurality of individual books in the predetermined sequence;
• rejecting a defective book from the sequence of books and leaving a space in the sequence of books;

• transferring the sequence of books from the spaced collating stations to a conveyor for conveying the sequence of books away from the spaced collating stations;
• and
• transferring the book that corresponds in sequence to the defective book from the spaced collating stations to the conveyor downstream from where the sequence of books is transferred to the conveyor and into the space in the sequence of books where the defective book was rejected from so that the books are in the predetermined sequence.
