ABSTRACT:
A method for coating with a liquid the window panel of a display tube by means of at least one brush mounted for rotation in a reservoir containing the liquid. As the partially submerged brush is rotated about its axis, drops of liquid picked up by the brush hairs are flung against the window panel. This method results in continuous mixing of the coating material and the return of the excess coating liquid back into the reservoir so that losses of the coating material are minimized.
