Title
(EN) METHOD AND DEVICE FOR CUTTING WOOD
(FR) PROCEDE ET DISPOSITIF DE DECOUPE DE BOIS
Abstract
(EN)
Method and device for cutting by means of a number of saw blades placed axially in a line next to each other and suspended to pivot in a cutting station connected to a trimming mill for trimming pieces of timber, whereby one or more cross-cutting saws designed for cutting are lowered for cutting via a guidance and control device. The relevant cross-cutting saw (11) is made to rotate for cutting in such a direction that its lower periphery, the one facing the conveyor (10) and piece of timber (17), moves opposite to the direction of motion of the piece of timber, that a down-deflecting means (36), suspended from the relevant arm (23), is brought into contact with the upper surface of the piece of timber that is fed forwards by the conveyor when the cross-cutting saw is lowered by its lower edge, and upstream of the cross-cutting saw (11) when seen in the direction of transport, whereby the piece of timber that is to be cut is pushed under the down-deflecting means by the driver pins (13), when the piece of timber is touched by the cross-cutting saw.

Un procédé et un dispositif pour couper au moyen d'un nombre de lames de scies placées axialement dans une ligne proche l'une de l'autre et suspendue de façon à pivoter dans un poste de coupe raccordé à une dégauchisseuse destinée à des pièces de bois de charpente, l'une au moins des scies transversales conçues pour couper étant abaissée pour couper via un dispositif de guidage et de commande. La scie de découpe transversale considérée (11) est mise en rotation pour couper dans une direction telle que sa périphérie, celle qui est tournée vers le convoyeur (10) et la pièce de bois de charpente (17) progresse dans le sens opposé du déplacement de la pièce de bois de charpente, ce qui fait qu'un déflecteur abaisseur (36) suspendu au bras considéré (23) est mis en contact avec la surface supérieure de la pièce de bois de charpente qui est entraînée vers l'avant par le convoyeur lorsque la scie transversale est abaissée par son bord inférieur, et en amont de la scie transversale (11) vue dans le sens du transport, ce qui fait que la pièce de bois de charpente à découper est poussée sous le déflecteur abaisseur par les broches d'entraînement (13) lorsque la pièce de bois de charpente est touchée par la scie transversale.
