Abstract
A cylindrical cutter head for a wood planing machine has mounted in its cumference a number of disposable knife blades which are clamped in place with the help of centrifugal wedges in lengthwise grooves. Between each disposable knife blade and each centrifugal wedge there is positioned a bracket of L-shaped profile consisting of a base strip which is immovably attached to the cutter head body and a clamping strip bearing against the knife blade, this clamping strip being elastically deformable to a small extent. By means of a conformal relation of a profiled region of the disposable knife blade with a corresponding profiled region of the clamping strip, the disposable knife blade is held firmly in position when clamped in. After loosening of the centrifugal wedge, the disposable knife blade can be easily withdrawn in a lengthwise direction and can be replaced with accurate positioning.
