Ink wiping system for an intaglio printing press

An ink wiping system for an intaglio printing press comprising a pressing device designed to exert pressure on a first surface of a displaceable wiping medium whose second surface, opposite the first surface, is positioned to wipe excess ink from the surface of a rotatable intaglio printing cylinder of the intaglio printing press,

• wherein the pressing device extends transversely to a direction of displacement of the wiping medium and is further designed to allow adjustment of a wiping pressure between the wiping medium and the intaglio printing cylinder at a plurality of transverse positions transversely to the direction of displacement of the wiping medium,
• wherein the ink wiping system comprises a plurality of pressing units that are distributed transversely to the direction of displacement of the wiping medium to allow adjustment of the wiping pressure between the wiping medium and the intaglio printing cylinder at the plurality of transverse positions transversely to the direction of displacement of the wiping medium,
• wherein each pressing unit comprises a position-adjustable pressing member designed to exert pressure on the surface of the wiping medium and an actuator designed to allow adjustment of a position of the pressing member and of the pressure exerted by the pressing member on the first surface of the wiping medium,
• and wherein the position-adjustable pressing member comprises a rotatable pressure ring positioned for rolling contact with a section of the surface of the wiping medium and a roller bearing having an outer cage secured to the inside of the rotatable pressure ring,
• the actuator being arranged inside an inner cage of the roller bearing to allow adjustment of a position of the rotatable pressure ring and of the roller bearing, thereby leading to adjustment of the pressure exerted by the rotatable pressure ring on the first surface of the wiping medium.

An ink wiping system for an intaglio printing press comprising a rotatable wiping roller assembly designed to wipe excess ink from the surface of a rotatable intaglio printing cylinder of the intaglio printing press,

• wherein the rotatable wiping roller assembly comprises:
• a rotatable hollow cylindrical body having an outer surface positioned to wipe the surface of the intaglio printing cylinder;
• and
• a pressing device disposed inside the hollow cylindrical body and designed to exert pressure on an inner surface of the hollow cylindrical body and to allow adjustment of a wiping pressure between the hollow cylindrical body and the intaglio printing cylinder,
• wherein the wiping pressure between the hollow cylindrical body and the intaglio printing cylinder is adjustable by the pressing device at a plurality of axial positions along the length of the hollow cylindrical body,
• wherein the pressing device comprises a plurality of pressing units that are distributed axially along the inside of the hollow cylindrical body to allow adjustment of the wiping pressure between the hollow cylindrical body and the intaglio printing cylinder at the plurality of axial positions along the length of the hollow cylindrical body,
• and wherein each pressing unit further comprises a shock absorber or damper to dissipate kinetic energy.
