Abstract (en)
[origin: EP0453868A1] A folding flap cylinder with a device is known, with which an adjustment of the folding flaps is possible during the rotation of the cylinder. In this folding flap cylinder, although the controllable folding flap and the fixed folding flap of each folding flap pair are adjusted simultaneously by a single control means in a pincer-like adjustment movement, the disadvantage of this device is that the control means is connected to each folding flap pair via its own respective multipart lever. It is likewise disadvantageous that each of these levers runs with its one end on a slanting plane which has a given friction to achieve self-locking. The result of this is high outlay in mounting and adjusting the folding flap cylinder. <??>In the device according to the invention for adjusting the folding flaps, both folding flap members (6, 7), which have the controllable folding flaps (4) or the fixed folding flaps (5) of each folding flap pair (3), are adjusted by the control element (325) via a correspondingly designed gear (314) which adjusts the two folding flap members in directions of rotation which are opposite to one another. Thus, irrespective of the number of folding flap pairs (3), only one single gear is necessary for the folding flap cylinder (1) for transmitting the control movement. Moreover, such a gear can be easily and rapidly adjusted and it guarantees a uniform loading of the elements of the adjustment gear even when the folding flap cylinder is used in group operation. <??>The invention can be applied to all folding flap cylinders. <IMAGE>
