ABSTRACT:
The present invention relates to a tank for the treatment of offset plates by ultrasounds. An elongated rectilinear passageway is limited by a lower wall constituted by a vat with a peripheral flange and by an upper wall constituted by an inverted vat with a peripheral flange, a seal incorporating an elastic lip being tightened between inlet and outlet openings, a bath reservoir being formed in one of the vats to contain an ultra-sound generator, so that the plates to be treated, propelled by pairs of rollers, pass through the developer bath whose volume is minimum, in a straight line.
