Abstract
A log shaping machine for cutting logs to a desired diameter and for cutting off root outgrowths, has a cutting ring with inwardly pointing tools which rotate with the ring. For the purpose of changing the effective cutting diameter of the tools the ring is rotatably supported on a gyratory frame moving generally parallel to itself so that each point of the gyratory frame moves periodically on a circle while the orientation in space of the gyratory frame is maintained. This gyratory motion of the gyratory frame may undergo adjustment in size by changing the radius of the said circle within the range from zero up to a maximum value by means of adjustable eccentrics on which the gyratory frame is suspended and which are also used for driving the gyratory frame.
