ABSTRACT:
An ink wiping device for an intaglio rotary printing machine comprises a tank for containing a cleaning liquid therein, an ink wiping roller rotatably supported in the tank and having a circumferential surface positioned for rolling contact with a printing plate of the intaglio rotary printing machine, the ink wiping roller having a portion immersible in the cleaning liquid, and a cleaning assembly disposed in the tank and immersible in the cleaning liquid for cleaning the circumferential surface of the ink wiping roller. The cleaning assembly includes at least one brush unit adjustably supported in the tank and having a plurality of rows of bristles having distal ends located in the vicinity of the circumferential surface of the ink wiping roller, and a cleaning sheet of synthetic fibered nonwoven cloth supported on the brush unit and interposed between the circumferential surface of the ink wiping roller and the distal ends of the bristles. Ink that has been removed and transferred from the printing plate to the ink wiping roller is wiped off the latter by the cleaning sheet pressed against the ink wiping roller under the resiliency of the bristles, and is dissolved into the cleaning solution.
