ABSTRACT:
A washing machine for a printing or processing table including an arrangement of two complementary carriages, each one of which rests on a lateral rail provided along opposite sides of the table for the tracking of the carriages. The carriages are solidly fixed to each other by means of a bridge element comprised of two telescopically arranged tubular bodies which are provided with adjustment and fixing means capable of securing the coupling of the tubular bodies to any relative dimension between two points, one of which is of maximum approximation while the other is of maximum separation. Each one of the carriages is provided with a cantilever arm directed inwardly of the table, which arms are longer than half the width of the table and support a plurality of circular brushes, each of the brushes being provided with a gear. The brushes are arranged in a zig-zag configuration and are suspended from pneumatic pistons the path of travel of which is greater than the distance which separates the brushes from the table and the pressure of which is limited by the action of a regulating valve. The telescopic tubes of the bridge are connected by a spindle and fixed nut device.
