Ink wiping system of an intaglio printing press and intaglio printing press comprising the same

摘要

There is described an ink wiping system (100; 100′; 100″) of an intaglio printing press comprising a wiping tank (101) and a rotatable wiping roller assembly (102; 102*) supported on and partly located in the wiping tank (101) for wiping excess ink from the surface of a rotatable intaglio printing cylinder (80) of the intaglio printing press. The ink wiping system (100; 100′; 100″) comprises a wiping roller retracting device (150) which forms an integral part of the ink wiping system (100; 100′; 100″) and is adapted to be coupled to the wiping roller assembly (102; 102*) to move the wiping roller assembly (102; 102*) between a working position (W) where the wiping roller assembly (102; 102*) is supported on and partly located in the wiping tank (101) for cooperation with the intaglio printing cylinder (80) and a parking position (P) where the wiping roller assembly (102; 102*) is retracted out of the wiping tank (101) and away from the intaglio printing cylinder (80). In the working position (W) of the wiping roller assembly (102; 102*), the wiping roller retracting device (150) is coupled to the wiping roller assembly (102; 102*). The ink wiping system (100; 100′; 100″) further includes, at the parking position (P), a storage section (110) adapted to receive the wiping roller assembly (102; 102*) which is retracted by the wiping roller retracting device (150).
