Abstract

L'invenzione concerne un procedimento ed una profilatrice bifrontale per l'attuazione del procedimento, per mezzo dei quali vengono realizzati e lavorati tagli obliqui paralleli sulle due superfici frontali di pezzi di legno longitudinalmente estesi, la profilatrice bifrontale presentando due metà di macchina 1, 2 simmetricamente conformate, le quali sono disposte ad entrambi i lati del percorso di passaggio dei pezzi di legno e sono equipaggiate con catene di trasporto 3, 4 azionabili in modo sincrono e della stessa lunghezza, per i pezzi di legno 22, con meccanismi di pressione della stessa lunghezza. Con seghe 6 e con gruppi di lavorazione trasversale 7. Secondo l'invenzione la distanza di lavoro delle due metà di macchina 1 e 2 viene regolata, perpendicolarmente alla direzione di passaggio D dei pezzi di legno 22, sulla grandezza della distanza predeterminata dei tagli obliqui paralleli da realizzare, le due metà di macchina 1, 2 vengono spostate relativamente l'una contro l'altra e parallelamente l'una verso l'altra, in direzione di passaggio dei pezzi di legno di un percorso S che corrisponde al prodotto della cotangente dell'angolo predeterminato ? di taglio obliquo per la distanza di lavoro delle due metà di macchina 1 e 2. Successivamente i pezzi di legno vengono appoggiati contemporaneamente con le loro due estremità sulle estremità di appoggio spostate delle due catene di trasporto 3 e 4 e vengono trasportate e lavorate in modo sincronizzato, ritmico o passo a passo dalla profilatrice bifrontale.Figura 2.The invention relates to a process and a two-faced profiling machine for the implementation of the method, by means of which parallel oblique cuts are made and machined on the two front surfaces of pieces of wood longitudinally extended, the two-faced profiling machine presenting two machine halves 1, 2 symmetrically shaped, which are arranged on both sides of the passage path of the pieces of wood and are equipped with conveyor chains 3, 4 which can be operated synchronously and of the same length, for the pieces of wood 22, with pressure mechanisms of the same length. With saws 6 and with transversal processing units 7. According to the invention the working distance of the two machine halves 1 and 2 is adjusted, perpendicular to the direction of passage D of the pieces of wood 22, on the size of the predetermined distance of the oblique cuts parallel to be made, the two machine halves 1, 2 are moved relative to each other and parallel to each other, in the direction of passage of the pieces of wood along a path S which corresponds to the product of the cotangent of the predetermined angle? of oblique cut for the working distance of the two halves of machine 1 and 2. Subsequently the pieces of wood are placed simultaneously with their two ends on the moved support ends of the two transport chains 3 and 4 and are transported and processed in a way synchronized, rhythmic or step by step from the two-faced profiling machine. Figure 2.
