A Falzmejserylinder, generally designated 1, 50 of the shaft lo the part 104 and the bore 105 has cylinder covers 2 and 2 ', each of which also rotates an axial movement and - since the shaft-generating folding knife axle bearings 3 and 3 ¹ carry on vvel - 11 is attached to the part 104 - it will also have two folding measuring devices 18 and 18 ¹ equal axial movement.

When the shaft 4 ¹ rotates, the inner council for rotary printing presses with feed vibrating plate 22 together with the eccentric ao roll and a knife cylinder pin 26 and the bearing 25 with a cutting knife cylinder causes a slight circumferential converging folding knife cylinder, with the movement. As a result of this movement, the folding knife in the folding knife cylinder changes to two folding knife positions of the stub shaft and which are mounted on it, and by means of one planctent intermediate gear wheels to the not shown and wheel on each folding knife shaft and at least on shafts 18 and 18 ¹ attached differential as one of the wheels cooperating with the Plauetenwheels, whereby the position of the shafts 18 and 18 ¹ gear are driven so that they cut the cut and the attached knives 19 and 19 ¹ into the gap between two sheets of paper Visibly changed the folding rollers, not shown, slide the folding rollers.
