An applicator (10) for applying a film of liquid to the surface of a work- piece 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 lubri- cant to the surface of the workpiece during such contact. The liquid applicator pro- vides 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 me- tered volumes of the liquid to the roller members.
