Abstract:
There is described a numbering device (1) for carrying out numbering in sheet-fed or web-fed numbering presses, the numbering device (1) comprising a casing and a numbering unit (6) with rotatable numbering wheels (7) carrying alpha-numerical symbols thereon, which numbering wheels (7) are disposed next to each other and rotate about a common rotation axis, the numbering device further comprising electro-mechanical actuation means for setting the position of the numbering wheels (7). The electro-mechanical actuation means are disposed in an inner space of the casing of the numbering device (1) and are mechanically autonomous, the electro-mechanical actuation means comprising a plurality of independent driving means (15, 18-23; 23*) for actuating a corresponding plurality of said numbering wheels (7). The numbering device further comprises calibration detectors (13) for calibrating the position of the numbering wheels (7) actuated by the electro-mechanical actuation means, each calibration detector (13) cooperating with at least one magnet (12) carried by the numbering wheel (7) to be calibrated. The calibration detectors (13) are carried by at least one supporting member (14, 14') located in an upper part of the numbering device, which supporting member (14, 14') extends parallel to the rotation axis of the numbering wheels (7).

The numbering device further comprises an electric motor (15) driving the associated numbering wheel through a gear-wheel assembly (16, 19-23; 23*). The gearwheel assembly (16, 19-23; 23*) comprises a driving pinion (23; 23*) meshing with a toothed wheel (16) disposed on a side of the associated numbering wheel (7), an axial position of the driving pinion (23; 23*) along its shaft (22) being adjustable.
Abstract:
An ink wiping system (100) for an intaglio printing press comprising a wiping tank (101) and a rotatable wiping roller assembly (102) positioned 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) comprises a supporting mechanism (200) coupled to the wiping roller assembly (102) for moving the wiping roller assembly (102) between a working position where the wiping roller assembly (102) is positioned in the wiping tank (101) for cooperation with the intaglio printing cylinder (80) and a maintenance position where the wiping roller assembly (102) is moved out of the wiping tank (101) and away from the intaglio printing cylinder (80).

Abstract:
There is described a numbering device (1) for carrying out numbering in sheet-fed or web-fed numbering presses, the numbering device (1) comprising a numbering unit (6) with rotatable numbering wheels (7) carrying alphanumerical symbols thereon, which numbering wheels (7) are disposed next to each other and rotate about a common rotation axis (17), the numbering device further comprising electro-mechanical actuation means for setting the position of the numbering wheels (7). The electro-mechanical actuation means are entirely located within the numbering device (1) and are mechanically autonomous, the electro-mechanical actuation means comprising a plurality of independent driving means (15, 18-23; 23*) for actuating a corresponding plurality of said numbering wheels (7).
Abstract:
There is described a numbering unit (6) of a numbering device (1), the numbering unit (6) comprising rotatable numbering wheels (7) carrying alpha-numerical symbols thereon, which numbering wheels (7) are disposed next to each other and rotate about a common rotation axis (17). The numbering unit (6) comprises a releasable indexing mechanism (50'; 7a', 510, 520) for mechanically aligning and maintaining the position of the numbering wheels (7) during a numbering operation, once the numbering wheels (7) have been rotated to their target positions. The releasable indexing mechanism (50'; 7a', 510, 520) comprises a movable indexing member (50'; 510) extending parallel to the rotation axis, which movable indexing member (50'; 510) is adapted to be pushed into indexing grooves (7a') provided on an inner periphery of the numbering wheels (7).
