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) .
