ABSTRACT OF THE DISCLOSURE. 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, 8-1/2" x 11" or A4 products and cross-folding them to 5-1/2" x 8-1/2 or A5 products.
