Abstract: A knife includes first and second edges, a ridge, a concave surface, and a planar surface. The edges are defined by intersections of out er edge forming surfaces on an outer side of the knife and inner edge forming surfaces on an inner side of the knife. The ridge is on the inner side and t he crest of the ridge is parallel to the first and second edges. The concave surface is between an inner edge forming surface and the ridge, and the planar surface is adjacent to the concave surface and between that first inner edge forming surface and the concave surface. A reference plane intersects the first and second edges, and a distance between any point on the concave surface and the reference plane is not less than a distance between any point on the planar surface and the reference plane.

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, f or example a drum, disc or truncated conical body, which supports a plurality o f 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 wo od side of the chipper knife comprises a cross-sectionally convexly bent surfac e 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 t he chipper knife. The invention also relates to a holder for such a chipper kni fe.

Abstract: LA INVENCIÓN SE REFIERE A UNA CUCHILLA ASTILLADORA DEL TIPO QUE SE ADAPTA PARA SER MONTADA EN ASTILLADORAS LAS CUALES TIENEN UNA HERRAMIENTA ROTATORIA, EN LA FORMA DE UN DISCO, TAMBOR O MIEMBRO FRUSTOCÓNICO, EN LA CUAL SE MONTA UNA PLURALIDAD DE TALES CUCHILLAS ASTILLADORAS PARA PROPORCIONAR, DURANTE LA ROTACIÓN DE LA HERRAMIENTA Y SIMULTÁNEA ALIMENTACIÓN DE TROZOS DE MADERA A LA MISMA, UN PROCESAMIENTO DE CORTE DE MATERIAL O DESINTEGRACIÓN DE LOS TROZOS DE MADERA EN ASTILLAS. LA CUCHILLA ASTILLADORA COMPRENDE AL MENOS UN BORDE DE CORTE (7) EL CUAL ES DEFINIDO ENTRE DOS SUPERFICIES DE FORMACIÓN DE BORDE (9 Y 10) CON UN ÁNGULO AGUDO ENTRE SI. AL MENOS UNA DE LAS DOS SUPERFICIES DE FORMACIÓN DE BORDE SE FORMA CON UNA PORCIÓN DE BORDE DE CORTE ENGROSADA (12) EN EL ÁREA PRÓXIMA AL BORDE DE CORTE, DICHA PORCIÓN DE BORDE DE CORTE ENGROSADA TENIENDO UN BORDE DE HOMBRO (13) HACIA EL RESTO DE LA SUPERFICIE DE FORNACIÓN DE BORDE Y FORMANDO UN ÁNGULO CON, O TENIENDO UN CENTRO DE CURVATURA DIFERENTE A, EL RESTO DE LA SUPERFICIE DE FORMACIÓN DE BORDE. LA INVENCIÓN TAMBIÉN SE REFIERE A UN MÉTODO PARA LA FABRICACIÓN DE UNA TAL CUCHILLA ASTILLADORA. EL PROBLEMA TÉCNICO ABORDADO, ES PROVEER UNA CUCHILLA EN DONDE SU GEOMETRÍA PUEDA SER AJUSTADA A DIFERENTES ASTILLADORAS, TIPOS DE MADERA Y CONDICIONES DE OPERACION.

Abstract: A knife for a disk chip cutting machine which is mounted between a carrier part and a clamping part and which includes a chip breaking surface extending into an opening adjacent an outer surface of the carrier part. The chip breaking surface includes a concave portion which terminates in a rib which extends outwardly and downwardly with respect to an interface between the knife and the carrier part with the concave portion being oriented to direct cut chips in a direction away from the outer surface of the carrier part during use.
