Abstract
Method and apparatus for belt sanding of lumber to finish and dimension lumber as rough sawn lumber is moved in single file through the mill. The lumber is moved at an angle of between about 5 to 15 degrees to the axis of the contact drum of a wide belt planer. This angular relationship of the lumber beneath the belt permits the high speed planing without overstressing the abrasive belt.
