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.
