Abstract

An apparatus is provided for coating workpiece members fed one at a time to a coating station whereat individual workpiece members are coated with a viscous coating medium supplied from a reservoir under constant hydrostatic pressure to ensure coating of said workpiece members with a predetermined amount of the viscous medium of such viscosity as to be suspended, without dropping, from the opening of tubes depending from a coating applicator at the coating station supplied with viscous medium from the reservoir at constant hydrostatic pressure. The workpiece members thus coated are moved along a track, preferably rolling about their axes, dried and collected.
