Abstract: A continuous tunnel batch washer of modular construction with the number of modules varying depending upon installational requirements and each module including a drum rotatably supported and driven to oscillate in a predetermined manner during the washing cycle and to rotate unidirectionally during transfer of the load from one module to a succeeding module with a unique chute or trough arrangement extending between the modules for transferring the wash load from one module to a next successive module. The drum in each module is roller supported and chain driven from a common shaft with a plurality of independent motors driving the shaft by a belt drive with each module including a reduction gear driven from the shaft and having an output driving the sprocket chain for the oscillatable and rotatable drum. A programmed control device provides continuous control of each batch of articles being laundered as they progress to the successive modules in the machine.
