A device for contact-free guidance of a web material over a surface element whereon a first longitudinal fold is formed in the web material, the surface element decreasing in width continuously from a top crossmember to a bottom crossmember, and being defined by boundary elements, the surface element and the boundary elements having gaseous medium provided therein, includes an adjustable closure element for varying, in accordance with a respective format of the web material guided over the surface, a flow of a volume of the gaseous medium from an air cushion formed beneath the web material; a device for forming the first longitudinal fold; and an angle-bar superstructure and a web-processing rotary printing machine, respectively, including the fold-forming device.

A device for cross cutting material webs includes a cutting-cylinder pair formed of mutually cooperating cylinders having respective cylinder cores and circumferential surfaces formed by exchangeable circumferential elements, the circumferential elements being arranged removably around the respective cylinder cores of the cylinders.

An apparatus for the transport and slowing of folding copies in a folding machine. The folding copies are transported by belt groups, and the copies are removed from a surface of the copy-guiding cylinder by the belt groups. At least two belt groups are provided for transporting the folding copies. A belt group preceding a longitudinal-folding device is driven by a drive that is independent of the folding machine drive.

Apparatus for the slowing of copies

A device for converting the function of a cutting/collecting cylinder (4) of a folding apparatus for rotary printing presses is provided. The cutting/collecting cylinder is convertible from a 'collect' to a 'non-collect' mode of operation and vice versa. Within the cutting/collecting cylinder (4) there is placed at least one group of pins (7), the pins (7) being disposed on a pin-bearing shaft (9) which can be actuated via a cam follower (41) rolling off on a cam body (27). The cam body (27) is adjustably mounted in a side wall (25) of the folding apparatus so as to be situated opposite a face side of the cutting/collecting cylinder (4). The relationship between the circumferential speed of the cutting/collecting cylinder (4) and the cam body (27) is changeable through a second power transmission element (34) which is coaxially movable and engageable with a first power transmission element (29) having at least two engagement areas (29a, 29b) .
