ABSTRACT:
A compact device which can be attached to a conventional printing plate developing machine either as a correcting agent washing station or as a developing station is provided. The device comprises an antechamber and a brush area which contains a brush roller, squeeze rollers, spray tubes, a doctor blade resting against the upper squeeze roller and a sealing blade resting against the lower squeeze roller. The squeeze rollers and the sealing blade create a fluid bath which reaches into an antechamber and the fluid level of which is limited by overflows in the side shields of the device. The antechamber is separated from the brush area by a partition. The brush roller is partially immersed in the fluid bath. In the antechamber, a spray tube is located through which fluid is fed into the fluid bath without spraying the printing plate surface. Pairs of feed rollers, transport the printing plate along an inclined feed table. A closeable bottom drain is closed during operation of the device and is opened for replacing the fluid bath.
