Abstract
An automated planer machine for planing a piece of lumber. The planer machine has a feed table for slidably receiving the bottom surface of the piece of lumber along a traveling course. One or more planing heads extend on sides of the traveling course to plane the surfaces of the piece of lumber. A linebar laterally guides the piece of lumber. Feed rolls along the traveling course move the piece of lumber. Positioning devices responsive to respective control signals are provided for adjusting a height of the feed table and planing levels of the planing heads as much when the planer machine is idle as during operation. Position encoders coupled to the feed table and the planing heads produce positional signals usable to accurately position them using the positioning devices.
