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).
