Abstract: To permit continuous adjustment of separating rollers (10, 11) positioned downstream of cutter cylinders (3, 4) cutting sheets (7) from a continuous web (1) during operation of the machine, to adjust for different lengths of cut sheets, and accelerate the cut sheets to the circumferential speed of a gripper apparatus, the separating cylinders (10, 11) are mounted on a first carrier structure (38) which is longitudinally moveable independently of the drive therefore with respect to transport belts (8, 9) passing beneath the separating rollers, the adjustment spacing between the separating rollers being controllable, for example by compressed air cylinders (55). Drives, in order to reduce noise, preferably are by gear belts driven from the cutter cylinders, to provide for synchronized operation of the transport or conveyor belts, the separating cylinders (10, 11) and of subsequent transport apparatus, such as a gripper cylinder (12).

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 al
