Title: INTAGLIO PRINTING PRESS
Abstract:
There is described an intaglio printing press (1; 1 *) comprising a plate cylinder (8) carrying one or more intaglio printing plates, the plate cylinder (8) receiving ink from an inking system (9, 20, 23; 20*, 23*) having a plurality of chablon cylinders (23; 23*) transferring ink directly or indirectly onto the plate cylinder (8), the intaglio printing press (1; 1 *) comprising an adjustment system acting on the chablon cylinders (23; 23*) in order to compensate elongation of the one or more intaglio printing plates. The adjustment system comprises, for each chablon cylinder (23; 23*), an adjustable drive unit, which adjustable drive unit (25) is interposed between the chablon cylinder (23; 23*) acting as a rotating output body of the adjustable drive unit (25) and a driving gear (100) acting as a rotating input body of the adjustable drive unit (25). The adjustable drive unit (25) is designed to allow selected adjustment of a rotational speed of the chablon cylinder (23; 23*) with respect to a rotational speed of the driving gear (100). In an adjusting state of the adjustable drive unit (25), driving into rotation of the chablon cylinder (23; 23*) is adjusted over each revolution of the chablon cylinder (23; 23*) 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 chablon cylinder (23; 23*) is performed exclusively mechanically via the adjustable drive unit (25), the chablon cylinder (23; 23*) rotating at a same rotational speed as the driving gear (100).
