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.

Versatile folding apparatus to provide folded products of selectively

To permit, selectively, assembly of different types of copy products (A1, A2), for example each containing different information, such as inserts advertising men's wear and ladies' wear, respectively, for a newspaper, first and second transverse severing and folding units (1, 8, 9, 10; 15, 18, 19, 20) are provided receiving, selectively, different portions (1a, 1b) of webs on which different copy product information is printed. An intermediate transport system (21, 25) is provided receiving, selectively, the first type of copy products (A1) from the first transverse severing and folding unit (1, 8, 9, 10) and, selectively, supplying the first type copy products with predetermined alignment to a folding flap cylinder (20) of the second severing and folding unit (15, 18, 19, 20), the second folding flap cylinder guiding the first copy products (A1) together with a severed, folded copy product (A2) of another type about a portion of its circumference and transferring the now joined copy products to, for example, a third folding unit (23) via an output transport system. The intermediate transport system which may include another folding flap cylinder (11) can be, selectively, enabled or disabled so that copy products can be supplied separately from either severing or folding units, for example via a delivery transport system (12, 13) and the current transport system (21, 22) separately. The separate webs may be cut portions from a single web which, for example, can be directed to the first severing and folding unit, for providing multiple folded inserts which can be selectively distributed by the intermediate transport system on the respective output transport system (21, 22) and the delivery system (12, 13).
