ABSTRACT:
To permit angular adjustment of a gripper system (51) on a pick-up cylinder with respect to the leading edge (c, d) of a sheet (b) of printed paper for folding intermediate the length thereof, for example in the center, by projecting a creasing blade (61') from a creasing mechanism (61) into a matching creasing groove (31) of a sheet receiving cylinder (3) as the sheet travels about the pick-up cylinder (2), the respective gripper and creasing blade systems (51, 61) are angularly adjustable about the central shaft (20) by support on end disks (52, 53, 62, 63) formed with camming surfaces in the shape of adjacently positioned rollers (56, 64; 55, 73) between which cone elements (81, 82) can be introduced, positioned radially offset from the axis of rotation so that, upon introduction of the cone elements and spreading of the respective rollers, angular rotation of the disks about the central operating shaft will result, thus positioning the respective disks angularly about the shaft in predetermined angular alignment. One of the camming surface rollers (73) can be coupled to a control arm (71) rotating under force of a drive motor (M, 41).
