ABSTRACT:
A wood incising roller where the teeth are formed by grooves in the roller surface and where some of such grooves cross others. Each cutting tooth has a knife-like cutting edge of finite length that is in one instance perpendicular to the axis of rotation of the roller and in another instance parallel to such axis. The grooves can be formed by machine cutting, either turning or grinding or by being molded in the surface and then shaped by a grinding operation. At least some grooves preferrably spiral about the roller. The pattern of cutting teeth and shape are determined by such variable parameters as pitch, number of thread starts, angle of cutter, depth of cut and lead angle. An incisor for lumber or veneer consists of two rollers at least one of which is as described in the forgoing. The grooves can be filled or partially filled with an elastic compressible material. The incising roller of the foregoing also is used in combination with a veneer lathe.
