Abstract
A wiping apparatus for an intaglio printing machine has a first wiping roller which is in rolling contact with a plate cylinder and which is driven in the same rotational direction as that of the plate cylinder; a second wiping roller which is in rolling contact with the first wiping roller and which is frictionally driven in the same direction as that of the first wiping roller; an ink scraper member brought into tight contact with the outer surface of the second wiping roller; an ink tray disposed under the first and second wiping rollers; and wiping paper having substantially the same width as each of the first and second wiping rollers, brought into contact therewith, and driven at a low speed in a direction opposite to that of movement of the wiping paper contacting surfaces of the first and second wiping rollers.
