In an apparatus for fastening together with the aid of staples a sheet signature comprising a plurality of sheets of papers laid one upon the other, a stitching unit (15, 16) is adapted for carrying staple blanks (54) and for movement relative a die (20, 21, 22) to urge said staple blanks through the sheet signature (12) such as to form a stitch fastening. Said die is arranged on the edge of a reciprocating folding knife (20), this edge facing towards the sheet signature, said knife coacting with a gap (27) or the like into which the knife urges the sheet signature for folding and simultaneous stitching. With an apparatus in accordance with the invention there is achieved that stitching, particularly of quarter folded products, can take place in-line in the same operation as folding, which enables building the apparatus into the printing press. The invention also relates to a method of using staples to fasten together the papers in a sheet signature. <IMAGE> |
