Abstract
An apparatus for cutting and folding printed products is provided. The apparatus includes a perforator, a first cutting device creating first slits in the web, a second cutting device creating second slits in the web longitudinally offset from the first slits so as to form a signature with a staggered edge, and a folder delta-folding the signature so that the staggered edge engages slots in the signature, the slots created by the perforator. A method of folding a printed product and a signature are also provided. Lead edges can be more easily prevented from dislodging and dog-earing and skewing can be minimized.
