Abstract: UNA CUCHILLA CHIPEADORA PARA UNA MÁQUINA CHIPEADORA, CUYA CONFIGURACIÓN PERMITA FABRICARLA A BAJO COSTO MANTENIENDO BUENAS CARACTERISTICAS DE CORTE Y PROPIEDADES DE FUERZA, DEL TIPO QUE SE ADAPTA PARA SER MONTADA EN UN CABEZAL DE CORTE ROTATORIO (1) EN LA FORMA DE UN CILINDRO, UN DISCO O UN DISCO CÓNICO TRUNCADO DE UNA MÁQUINA CHIPEADORA PARA CORTAR PIEZAS DE MADERA EN TROZOS MÁS PEQUEÑOS. LA CUCHILLA (2) COMPRENDE UNA SECCIÓN TRANSVERSAL CON SIMETRÍA ESPECULAR, DOS BORDES DE CORTE OPUESTOS (5, 5'), UNA PENDIENTE DE DEFLEXIÓN (13) EN UN LADO INTERIOR DE LA CUCHILLA CHIPEADORA Y REBAJES PARA EL ASENTAMIENTO DE LA POSICIÓN (11, 11') EN UN LADO EXTERÍOR DE LA CUCHILLA CHIPEADORA. LA PENDIENTE DE DEFLEXIÓN ES POSICIONADA CENTRALMENTE ENTRE, Y EN PARALELO A, LOS BORDES DE CORTE Y TIENE UNA CRESTA QUE SE PROYECTA DESDE DICHO LADO INTERIOR. UNA SUPERFICIE DE GUIA DE LOS TROZOS PEQUEÑOS (14, 14') SE FORMA DESDE UNA SUPERFICIE DE FORMACIÓN DE BORDE (10, 10') EN CADA UNO DE LOS BORDES DE CORTE HASTA LA CRESTA DE LA PENDIENTE DE DEFLEXIÓN Y COMPRENDE UNA SUPERFICIE DEFLECTORA DE TROZOS PEQUEÑOS CURVADA EN FORMA CÓNCAVA (16, 16'). CADA SUPERFICIE DE GUIA DE LOS TROZOS PEQUEÑOS (14, 14') SE FORMA A PARTIR DE SUPERFICIES CÓNCAVAS Y PLANAS CONTIGUAS QUE SE UNEN TANGENCIALMENTE EN UNA DIRECCIÓN DESDE UN ÁREA INMEDIATAMENTE ADYACENTE A LA SUPERFICIE DE FORMACIÓN DE BORDE (10, 10'; 21, 21') HASTA LA CRESTA DE LA PENDIENTE DE DEFLEXIÓN (13) SIN NINGUNA PORCIÓN INTERMEDIA O INDENTACIONES CURVADAS EN FORMA CONVEXA QUE GENEREN DISCONTINUIDADES O CAMBIOS ABRUPTOS EN LA DIRECCIÓN DE LA SUPERFICIE DE GUIA DE LOS TROZOS PEQUEÑOS Y COMPRENDE UNA PRIMERA SUPERFICIE DE CONTACTO PLANA (15, 15') LA CUAL ES ADAPTADA PARA ASENTARSE CONTRA UN MIEMBRO DE SUJECIÓN INTERIOR (4) Y LA CUAL SE FORMA EN LA SUPERFICIE DE GUIA DE LOS TROZOS PEQUEÑOS (14, 14') ADYACENTE A LA CRESTA CONVEXA DE LA PENDIENTE DE DEFLEXIÓN (13). LA INVENCIÓN TAMBIÉN SE REFIERE A UN SISTEMA DE MONTAJE DE LA CUCHILLA CHIPEADORA ASL COMO TAMBIÉN A UN MÉTODO PARA MONTAR UNA CUCHILLA CHIPEADORA EN UN CABEZAL DE CORTE ROTATORIO.

Abstract: The block comprises a flat or cone-shaped plate with cutting blades (2) mounted on it so that one end of the blade cutting edge (6) is closer to the block rotation axis than the other end. The cutting edge is bordered by a timber guide surface and a chip guide surface (13), the timber guide surface having an angle relative to its rotation plane which varies over its length, so that the largest angle is at the end of the cutting edge closest to the rotation axis and the angle then reduces in the outwards direction. The chip guide surface also has an angle relative to its rotation plane which varies over its length, so that the angle at the end of the cutting edge closest to the rotation axis increases in the outwards direction, ensuring that the cutting edge angle between the timber and chip guide surfaces remains essentially constant over the entire length of the cutting edge.

Abstract: A knife for disk type chip cutter machines with a circular rotatable cutter disk (10) on its first axial side being provided with several knives running from the disk centre to its periphery. An opening (14) is provided in the di sk in connection with each knife. The opening (14) has a chip guiding surface t o guide separated chips to the other axial cutter disk side. The knife include s a knife carrier, on which the knife is fixed between a first carrier part (1 8) provided essentially in line with the first axial cutter disk surface and second carrier part (16) extending downwards in the opening from said cutter disk surface into the cutter disk inside and being a part of the chip guidin g device. The knife (12) is on its side facing the other carrier part provided with a chip breaking surface (22) passing the other carrier part (16) into t he opening and protecting said carrier part from wear in that the separated chi ps by means of the chip breaking surface are guided in a direction away from th e carrier part.

Abstract: The invention relates to a chipper knife for chippers of the type comprising a tool ( 12 ) which is rotatable on an axis of rotation and is in the form of, for example a drum, disc or truncated conical body, which supports a plurality of such chipper knives. The chipper knife comprises at least one cutting edge ( 1 ) which is formed between a flank ( 2, 2 ') and a chip guiding surface ( 4, 4 '), and two opposite main surfaces ( 3, 3 ') which are adapted to abut against and be retained on the opposite seats ( 14, 15 ) of a holder ( 9, 10 ) on the tool. At least one main surface ( 3, 3 ') of the chipper knife which is located on a wood side of the chipper knife comprises a cross-sectionally convexly bent surface portion ( 6, 5 ') which connects to and extends backwards from the flank ( 2, 2 ') and the chord of which constitutes at least 20%, preferably at least 30% and, most preferably, at least 40% of the total cross-sectional length of the chipper knife. The invention also relates to a holder for such a chipper knife.

Abstract: A clamping assembly to hold a woodworking knife in place in a woodworking machine. The clamping assembly comprises a clamping component comprising a body and an actuator. The body has three discrete contact positions distributed thereon: 1) a fulcrum located generally at one end, 2) a knife abutting portion located generally at the other end, and 3) a bearing surface located elsewhere. The actuator is for applying a clamping force to the body along a clamping axis located intermediate of the knife abutting portion and the fulcrum. The fulcrum is a surface having a normal that is at an angle to the clamping axis. The bearing surface is a surface wherein a line normal to the bearing surface intersects the line normal to t he fulcrum at a position outside of the clamping component at a location farthe r askew of the clamping axis than the fulcrum.
