ABSTRACT:
Apparatus is provided for applying a thin film of liquid to a workpiece. Although the apparatus with be described as a convenient means for waxing skis, it will become apparent as the description proceeds that it has wider application. The apparatus includes a motor driven drum which is dipped in a pan containing the liquid to be applied to the workpiece, and which when rotated causes a coating of the liquid to adhere to the surface of the drum. A metering rod, which may be flat, round, or of any other appropriate shape, is supported on the surface of the drum in a position extending parallel to the axis of rotation of the drum. The metering rod has sufficient weight so that it does not turn with the drum but rests against a stationary support bracket which is mounted on the frame of the apparatus adjacent to the drum, and which also extends parallel to the axis of rotation of the drum. However, with a round metering rod, the metering would still be accomplished even if it rotated. The metering rod is shaped to define a predetermined space between its surface and the surface of the drum, and this space determines the thickness of the liquid coating adhering to the drum surface.
