ABSTRACT:
Apparatus for processing light sensitive sheet or roll material includes a plurality of processing stations for applying solutions to the surface of the material. A movable endless web partially immersed in a wash tank has a portion of its path outside of the tank for transporting sheet material to be processed past the processing stations.
Means are provided for placing the sheet material on the web at one end of the path portion outside the tank and for removing the material at the other end of the path portion. The continuous circulation of the web through the wash tank removes any processing solutions and debris from the web.
Means are provided for periodically purging the processing stations with cleaning solution which is also removed in the wash tank.
