Abstract:
A method of fabricating a printed product from folded signatures of printed sheets comprising the steps offorming folded edges of the printed sheets for providing folded signatures;placing the folded signatures astride on a saddle-shaped transport and collection path;moving the folded signatures astride on the saddle-shaped transport and collection path;perforating the folded edges of the signatures while the folded signatures are moving by providing a slotted perforation which at least approximately penetrates the height of the fold and wherein the perforation is performed such that the folded edge of the innermost signature of a printed product is not being perforated;applying an adhesive to the folded edges of the signatures while the signatures are moving;partially conglutinating the signatures to each other at the folded edges to form a bound spine.
