ABSTRACT:
A web (17) received, for example, from an 8-page or 16-page printing machine, is severed in a cutter blade cylinder (6) needle-tucking blade cylinder (7) combination and the severed sheets are provided with a cross fold in a first system (A) formed by the combination needle-tucking blade cylinder (7) and a combination needle-cutter blade cylinder (12), to be then further cross-folded and cut in a second system formed by the combination of the needle-cutter blade cylinder (12) with a needle-folding jaw cylinder (13). To permit the second combination to be operative, the combination needle-cutter blade cylinder (12) is additionally formed with tucking blades (21) for engagement in the folding jaws (22) of the needle-folding jaw cylinder (13). This arrangement permits double cutting and folding, for example, of longitudinally folded superimposed webs into, selectively, 81/2".times.11" or A4 products and cross-folding them to 51/2".times.81/2 or A5 products.
