DEFINITION

Classification: 118/407

(under subclass 400) Coating apparatus wherein the pool of coating material is confined, retained or supported at least in part by a surface of the work being coated, relative motion between the work and the confined coating material separating a film of the material adhering to the work.

(1) Note. In this and the indented subclasses may be found, for example, hoppers or containers for coating material positioned above the base to be coated with an open bottom of the hopper or container directly in contact with the base to be coated so that the bottom of the batch of coating material is supported at least in part by the base being coated. Also in this subclass may be found the so-called striping devices

in which coating material is fed under pressure through a thin tube and into direct contact with a moving base, the column of coating material being supported up to the instant of contact with the base material.
