Abstract
An improved system for clamping and retaining a cutting knife in position in an apparatus for processing wood. The apparatus includes a support surface, a cutting knife, an associated holding location on the support surface to receive the cutting knife, and a clamp member having a clamping surface to engage and hold the at least one cutting knife in the associated holding location. The improvement involves mounting the clamp member to the support surface at a pivot joint for pivotal movement of the clamp member with respect to the support surface. The clamp member has a clamping surface that extends on one side of the pivot joint and a lever arm extending on the other side of the pivot joint. An actuating member is provided to apply a force to the lever arm so that a clamping force is applied to the cutting knife through the clamping surface according to the principle of a first order lever. The pivoting clamping arrangement provides secure and reliable clamping of the cutting knives. The pivoting joint between the clamp member and the support surface tend to evenly distribute the clamping force along the length of the cutting knife for better retention of the knife.
