Title
(EN) METHOD FOR THE SAWING OF A LOG AND A GADGET FOR A DISK SAW OR BAND SAW
(FR) PROCEDE DE SCIAGE D'UNE GRUME ET APPAREIL POUR SCIE CIRCULAIRE OU SCIE A RUBAN
Abstract
(EN)
The invention relates to a method used in sawing a log with a circular sawmill or band saw, in said method a log (8) is placed on a moving traveling table (4), and in which the traveling table and the log are moved with one to-and-fro movement and a saw-cut (27) is sawed into the log with a circular saw or band saw blade (1), and with two or more secondary circular saws (9, 10), placed perpendicularly in relation to the primary blade (1), two or more horizontal saw-cuts (23, 24, 25, 26) are simultaneously sawed, whereby one or more units of prepared sawed lumber (22) are obtained with one to-and-fro movement. Additionally, the invention relates to a circular sawmill or band saw accessory, as presented in the first of the accessory claims. In a method applied according to the invention, the traveling table (4) for the log (8) is mounted with a lifting device (11), on top of which the top end of the log is placed and by which the elevation of the top end of the log is adjusted in relation to the blades. In an accessory formed in accordance with the invention, the traveling table (4) for the log (8) comprises a lifting device (11) for adjusting the elevation of the top end of the log.
(FR)
L'invention concerne un procédé de sciage d'une grume à l'aide d'une scie circulaire ou d'une scie à ruban. La grume (8) est disposée sur une table mobile (4) qui est déplacée suivant un mouvement alternatif assurant ainsi la coupe (27) de la grume à l'aide d'une scie circulaire ou d'une lame (1) de scie à ruban. Deux ou plusieurs scies circulaires auxiliaires (9, 10) sont perpendiculaires à la première lame (1), deux ou plusieurs découpes horizontales (23, 24, 25, 26) sont effectuées simultanément pour obtenir une or plusieurs unités de bois de sciage (22) grâce au mouvement alternatif. L'invention concerne en outre un accessoire pour scie circulaire ou scie à ruban tel que décrit dans les revendications correspondantes. Selon un procédé mis en oeuvre, la table mobile (4) pour la grume (8) est montée à l'aide d'un dispositif élévateur (11) sur lequel repose la grume et grâce auquel est assuré le réglage de l'extrémité supérieure de la grume par rapport aux lames. Selon une variante, la table mobile (4) comprend un dispositif élévateur (11) permettant de régler l'élévation de l'extrémité supérieure de la grume.
