PLATE WIPING MECHANISM FOR INTAGLIO PRESS

The plate wiping mechanism includes a wiping roll running in the opposite direction to and having its surface in rubbing contact with the printing plate of the intaglio press. The wiping roll is journaled in the sides of a tank containing an ink solvent, so that the periphery of the wiping roll moves from its position of contact with the plate through a bath of ink solvent, and then moves again to engage the plate. The wiping roll is driven from the main drive of the press through a control system by which the rotational speed of the wiping roll may be set as an adjustable proportion of the speed of the printing plate. The wiping roll is also arranged for endwise reciprocation with respect to the intaglio plate. The motor for driving the wiping roll in its endwise reciprocation is also controlled at a speed adjustably proportional to the speed of the intaglio plate.
