Abstract
A counter blade is disclosed for use in a chipping machine which comprises a chipper disc rotatably mounted in the chipper frame by means of a shaft supporting the disc. The counter blade is attached to the chipper frame essentially at the intersection of a blade mounted in the chipper disc and the log to be chipped, in such manner that, on the side opposite to the chipping blade, the counter blade rests against the log to be chipped. The counter blade consists of a first and a second blade part placed at an obtuse angle relative to each other. According to the present invention, the counter blade consists of two essentially elongated elements having an arris forming the cutting edge of the counter blade at least on one of its longitudinal sides. The end faces of the counter blade elements are so formed as to permit connection to an adjacent counter blade element so that two counter blades form a continuous cutting edge of the counter blade.
