Abstract
A method of binding folded signature sections together into a book comprised of a signature comb element having teeth which are inserted through perforations in the fold of the signatures and the teeth having tabs which secure the signature comb in slots between two or more spine tapes. The spine tapes adjustably lock into the hinge of the covers by a tooth and pawl mechanism, further interlocking one or more signatures to the spine of the book and securely fasten together the signatures and book cover.
