Title
(EN) BARKING METHOD, AND AN APPARATUS FOR UTILIZATION OF THE METHOD
(FR) PROCEDE D'ECORCAGE ET APPAREIL DE REALISATION DUDIT PROCEDE
Abstract
(EN) A barking method, and an apparatus for utilization of the method, in which a log (6) during a substantially linear feeding movement is brought to pass one or a number of barking means (1; 4, 4'), arranged to perform a surrounding and rotary movement in relation to the log (6). According to the invention, the barking means (1; 4, 4') are pressed into a contact position by influence from centrifugal force during a surrounding and rotary movement in relation to the log (6). The contact pressure of the barking means (1; 4, 4') is continuously variable by increasing/decreasing the rotary speed of the barking means (1; 4, 4') in relation to the log (6). The barking means (1; 4, 4') can be arranged inclined in relation to the feed direction of the log (6), in order to cause a feed movement for the log (6) in direction past the barking means (1; 4, 4').
(FR) Un procédé d'écorçage utilise un appareil grâce auquel un tronçon de bois (6), effectuant un mouvement d'avance essentiellement linéaire passe par un ou plusieurs organes d'écorçage (1; 4, 4'), conçus pour effectuer un mouvement entourant et rotatif par rapport au tronçon de bois (6). Selon la présente invention, les organes d'écorçage (1; 4, 4') sont pressés l'un contre l'autre par application d'une force centrifuge durant un mouvement entourant et rotatif par rapport au tronçon de bois (6). La pression de contact des organes d'écorçage (1; 4, 4') peut être variée continuellement par augmentation/diminution de la vitesse rotative des organes d'écorçage (1; 4, 4') par rapport au tronçon de bois (6). Les organes d'écorçage (1; 4, 4') peuvent être disposés de façon inclinée par rapport à la direction d'avance du tronçon de bois (6), afin de permettre à celui-ci d'effectuer un mouvement d'avance dans une direction passant par les organes d'écorçage (1; 4, 4').
