In order that no undue strain be placed on 'the film, the sound-track-treating unit is tendency-driven, that is, the shafts in the rollers of the drying cabinet are turning in loose rollers. After leaving the drying cabinet, the film is fed over a roller cluster to guide it accurately over the edgetreating roller (Fig. 7). Here, the sound-track area comes in con Fig. 8 tact with a bead of the edge-treating solution carried on the slightly concave periphery of the applicator wheel. The bead wheel travels at a slightly faster rate of speed than the film and in the same directions as the film. This maintains a uniform bead in contact with the track area. The amount of solution applied is controlled by the depth of dip of the applicator wheel in the solution, and lateral movement of the wheel is controlled by two micrometer adjustments on the applicator assembly. With these adjustments, no difficulty has been experienced in confining the track area within the established standard.
