ABSTRACT:
An apparatus for applying a uniform liquid coating to selected portions of an outer surface of an object having a convex horizontal cross section and a constant vertical profile is disclosed. An application pad having a surface contoured to approximate the constant vertical profile of the object acts as a liquid reservoir. The object is transported in a rolling contact with the application surface sufficient to ensure uniform application of the liquid to the surface of the object without substantial deformation of the application pad surface. A support for maintaining the application pad in an orientation such that rolling contact with the surface of the object is provided. Liquid is supplied to the application pad in an amount sufficient to wet the application pad surface and uniformly dispense liquid to the outer surface of the object.
