Abstract: Disclosed is a method for testing, adjusting and maintaining the viscosity of paint used in a vacuum applicator painting apparatus. By maintaining the paint viscosity within an optimum range, a layer of paint is applied to all surfaces and edges of workpieces to be painted is in a most economical, efficient and complete manner. Also disclosed is an improved painting apparatus of the vacuum applicator type for uniformly and efficiently painting large numbers of workpieces such as plywood boards.

Abstract: An automated machine for continuously puttying the side edges of a plurality of elongated plywood boards is disclosed. The device includes a laterally adjustable conveyor system for accommodating boards of various widths. Also included are a pair of opposed putty applicator heads for simultaneously applying putty under pressure to both side edges of the plywood boards as the boards pass thereby. Excess putty striking or wiping devices are included for wiping excess putty from the side edges of the boards which is applied by the putty applicator heads. The machine quickly, efficiently and completely putties the side edges of large numbers of plywood boards rapidly and continuously in a mass production operation.
