Abstract
Apparatus for surface cutting logs to provide a finished surface corresponding to the natural surface contour of the log or to impart a predetermined distinctive surface contour thereto and a method of effecting such surface contouring; said apparatus comprising log guiding and feeding means for moving a log planed at diametrically opposite sides to have spaced parallel top and bottom surfaces and diametrically opposed debarked side surfaces or a log planed on all four sides so as to have spaced parallel top and bottom surfaces and spaced parallel side surfaces, cutting instrumentalities located at longitudinally spaced intervals along the path of movement of the log at different peripheral positions which collectively remove material from the side surfaces and guides associated with the cutting instrumentalities operable to control movement of the cutting instrumentalities in accordance with deviations in the surface of the log or according to a predetermined programmed pattern.
