ABSTRACT:
Log turning apparatus is disclosed for rotating an axially travelling log about its longitudinal axis, use being made of a pair of spaced rotatably supported spiked rollers that are arranged on opposite sides of the log, each of said rollers being contained in a plane angularly arranged relative to the axis of the log. The rollers are biased together into frictional peripheral engagement with the peripheral surface of the log, whereupon the rollers are axially displaced in opposite directions to rotate the log about its axis. Preferably the rollers are rotatably supported at the ends of support arms the other ends of which are pivotally connected with the frame of the apparatus. The log is normally horizontal and the rollers are normally vertical and contained in a common plane normal to the longitudinal axis of the log, said support arms being connected with the frame for pivotal movement about either horizontal or vertical pivot axes.
