An applicator (10) for applying a film of liquid to the surface of a workpiece by contact transfer. The apparatus utilizes one or more roller members (12, 14) rotatably contacting a workpiece as it is advanced for manufacture or finishing and transferring a desired liquid as a lubricant to the surface of the workpiece during such contact. The liquid applicator provides an accurately metered supply of the lubricant to be applied to the roller, such that the amount so applied is accurately controlled and regulated, preferably by use of a positive-displacement pump (72) for repeatedly metering out and directing metered volumes of the liquid to the roller members.
