Zusammenfassung: | The binding of books in signature form has little changed from antiquity. Whether binding is done by hand, or by machine, the pages of a book are so printed that groups (signatures), usually of no less than sixteen pages, can be sewn together in binding. Since we are printing in two-page forms (folio imposition), that means that a signature will consist of four sheets, each folded once down the middle and laid one inside another. The outside sheet will carry the first and last pages of the signature, say pages 1 and 16, on one side, backed up by pages 2 and 15. The next sheet will carry pages 3 and 14, backed up by 4 and 13. And so on to the middle of the signature, where pages 8 and 9 will form the center spread.
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. |
