Abstract: A rotary-blade folding unit includes at least one folding blade, a pair of folding rollers and a drive for producing a hypocycloid movement of the folding blade about a rotational axis of the folding blade and a main rotational axis for folding a signature that has been guided up to the rotary-blade folding unit in a transport plane extending between the main rotational axis and the folding rollers, and further includes a drive mechanism for producing an oscillatory movement of the folding blade at least approximately parallel to the main rotational axis; a folder including the folding unit; and a printing machine in combination with the folder.

Abstract: The present invention relates to a copy-carrying cylinder which has a peripheral surface (2) supporting sheet-like copies and which is provided with retaining elements for fixing the sheet-like copies in place on the peripheral surface (2). A folding device (5) which can be moved into and out of openings (4) at the peripheral surface (2) are bounded by at least one movable surface element (13). The surface element (13, 13.3) which is associated with the folding device (5) is designed in such a manner that it takes its closed position (22) automatically.

Abstract: In a folder, a folding cylinder having folding components accommodated on the periphery thereof and being phase-dependently operatable, and cylinder segments for carrying the folding components, the cylinder segments being adjustable in relation to one another and being mounted coaxially in side walls, includes separate drives, respectively, for driving each of the folding components, a rotary leadthrough via which energy is supplied to the separate drives, and a speed controller for speed-dependently controlling the separate drives; a method of operating the folding cylinder; a folder including the folding cylinder; and a rotary printing machine in combination with the folder including the folding cylinder.

Abstract: A device for tensioning first and second transport belts in a folder of a rotary printing press including mutually independent transport belt systems wherein the first and second transport belts are disposed, includes a tensioning unit for tensioning the first and second transport belts. The tensioning unit is disposed between the first transport belt and the second transport belt and serves for acting thereon with a force that tensions the first and second transport belts simultaneously.

Abstract: 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) .
