process for the production and processing of the oblique cuts on the two surfaces parallel frontal pieces of wood

摘要

the invention relates to a process and a profilatrice bifrontale for the implementation of the process.by means of which the oblique cuts are made and processed in parallel on the two surfaces of longitudinally extended front pieces of wood.the profilatrice bifrontale by presenting two half car 1, 2 symmetrically complied with.which are arranged at both sides of the path of movement of pieces of wood and are equipped with transport chains 3, 4 operable in synchronous mode and the same length.for the wooden pieces 22, with mechanisms of blood pressure of the same length. with saws and with groups of cross processing 6, 7.according to the invention, the distance of the two halves of the car 1 and 2 is regulated, perpendicular to the direction of passage of the wooden pieces 22.the size of the predetermined distance of the oblique cuts parallel to achieve, the two halves of the car 1.2 are moved relatively against one another and parallel one to the other.in the passing direction of the pieces of wood in a path that corresponds to the product of the cotangent of the angle predetermined? oblique cutting by the distance of the two half mthe car 1 and 2.then the pieces of wood are supported at the same time with their two ends on the ends of support move of the two transport chains 3 and 4 and are transported to and.you in time, rhythmic, or step by step from the profilatrice bifrontale. figure 2.
