(under subclass 407) Coating apparatus in which at least a portion of the pool receptacle wall in contact with the work at the point of departure of the work from the pool determines the thickness of the film of coating material retained on the work and in which the wall portion is mounted for motion to (1) vary the spacing between the wall portion and the work and/or (2) obtain a relative motion between the working face of the wall portion and the work.
(1) Note. The difference between the subject matter of this subclass and the subject matter of subclass 100 is that the subject matter of the present subclass has a movable member which is part of the coating material supply chamber. In subclass 100 the movable members, for determining the thickness of the coating, contact the coating after application of the coating material to the base and are distinct and separate instrumentalities from the coating material supply.
