    摘要: A multihead incisor for incising at least two sides of lumber or timber and in one pass produces a higher incision density than can be achieved without two or more passes on existing single roll incisors. The incisor comprises at least two sets of incisor rolls, each set having two or more rolls spaced apart in one plane representing a side of a piece of lumber or timber moving in the one plane, a first incisor roll in each set having incising teeth positioned to make a pattern of incisions in the one plane, a second incisor roll in each set, downstream of the first incisor roll, positioned to make a second pattern of incisions over the first pattern of incisions in the one plane, and a system to synchronize rotation of the first and second incisor rolls in each set to ensure combination of the first and second patterns of incisions is to a predetermined final pattern of closely spaced apart incisions on at least two sides of a piece of lumber or timber.

    摘要: A process and apparatus for forming a wood grain simulation pattern on surfaces of synthetic articles such as synthetic lumber planks. The articles are fed along a predetermined path on a conveyor surface. A plurality of cutting blades are disposed about the periphery of a rotatable cylindrical element supported on a drive shaft. As the synthetic article is fed under the rotatable cylindrical element which is in rotation, the blades which are disposed across an outer surface of the article on which a grain simulation is desired, cut a plurality of short slits spaced laterally from one another in an offset pattern. These slits extend along the feed axis of the article and simulate a wood grain in the outer surface thereof.

    摘要: 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.
