APPARATUS FOR PLANING AND DISINTEGRATING WOOD, SYNTHETIC RESIN AND OTHER MATERIALS

摘要

A planing apparatus comprises a knife replaceably mounted in a carrier and having two parallel major faces and two parallel minor faces inclined with respect to the major faces whereby the cross section of the knife forms a parallelogram, each of the minor faces forming a knife edge at their intersection with the major faces. A knife support supports the knife in the carrier and includes a first transverse ledge holding the knife in place and a second transverse ledge spaced from the knife. The second ledge has a thickness in slight excess of the thickness of the knife.
