There is described an adjustable drive unit of a printing press (1; 1*), which adjustable drive unit (25) is interposed between a rotating input body (100) and a rotating output body (23, 200; 23*, 200) to allow selected adjustment of a rotational speed of the rotating output body (23, 200; 23*, 200) with respect to a rotational speed of the rotating input body (100). In an adjusting state of the adjustable drive unit (25), driving into rotation of the rotating output body (23, 200; 23*, 200) is adjusted by means of an adjustment motor (300) of the adjustable drive unit (25). In a non-adjusting state of the adjustable drive unit (25), the adjustment motor (300) is inoperative and driving into rotation of the rotating output body (23, 200; 23*, 200) is performed exclusively mechanically via the adjustable drive unit (25), the rotating output body (23, 200; 23*, 200) rotating at a defined rotational speed with respect to the rotating input body (100). Also described is a printing press, especially an intaglio printing press (1;1*) comprising such an adjustable drive unit (25). |
