ABSTRACT:
A machine for making wood moldings includes an endless feed belt extending downstream from the upper face cutter head for holding short lengths of wood pieces securely between the working stretch of the feed belt and the underlying bed plate and delivering it through side and lower face cutter heads. An air plenum container overlies and bears against the working stretch of the feed belt to provide uniform feed pressure to the wood throughout the length of the working stretch and delivers air under pressure through a multiplicity of holes in the plenum container to the confronting side of the working stretch of the belt for minimizing friction between the belt and container. Short lengths of wood pieces are delivered in spaced-apart relationship to the upper face cutter head between an elongated side feed belt and an elongated air fence.
