Abstract: The present invention describes a coated CBN cutting tool for metal machining. The tool is composed of one or more CBN bodies with or without a cemented carbide backing. The coating comprises one or more layers of refractory compounds of which at least one layer consists of fine-grained, crystalline &ggr;-phase alumina, Al2O3, with a grain give less than 0.1 &mgr;m. The &ggr;-phase alumina is deposited with a Plasma Activated Chemical Vapor Deposition (PACVD) process in which the plasma is produced by applying a bipolar pulsed DC voltage across two electrodes to which the tool substrates to be coated are fixtured and electrically connected.

The coating is composed of one or more layers of refractory compounds of at least one layer of fine-grained, crystalline &ggr;-phase alumina (Al2O3) with a grainsize less than 0.1 &mgr;m. The Al2O3-layer is deposited with a bipolar pulsed DMS technique (Dual Magnetron Sputtering) at substrate temperatures in the range 450° C. to 700° C.

Abstract: There is provided a coated cutting insert particularly useful for finishing operations in milling of grey cast iron. The insert has a fine-grained WC-Co cemented carbide body and a coating of multiple layers of TiC.sub.x N.sub.y deposited at conditions aiming to minimize the decarburization of the cutting edge without any negative effects on the substrate. There is also disclosed a method of applying a TiC.sub.x N.sub.y layer by CVD technique on a cemented carbide cutting insert without eta phase formation and without etching of the binder phase.

Abstract: A method for packing bodies (3), e.g. fodder bales of a generally cyclindrical or parallelpipedic configuration, in continuous material, such as plastics, comprising a support of the body and a winding of continuous material around the body from at least one magazine with continuous material while rotating the body around a first axis (7) of the body by means of a roller arrangement including at least one roller device (5'), downwards to which the body envelope surface (9) then rotates, is adapted to approach the body envelope surface. The invention also relates to a device for packing bodies.

Abstract: A method for packaging bodies (1), primarily bales (1) of moist or wet animal-feed, by wrapping the body in a thin plastic film band (2), wherein a plastic web is wound onto the body in successive turns (3) while maintaining the web in tension. The web is taken from a magazine (4) while rotating the body about its longitudinal axis (5), which is preferably essentially horizontal, with the turns extending generally parallel with and transversely to the longitudinal axis, wherein wrapping of the body is terminated by gripping the web at a web part located between the magazine and the body, therewith severing the web. The method is mainly characterized in that the plastic web (2) is caused to extend transversely to the longitudinal axis (5) and herewith run from the magazine (4) essentially tangentially to the body (1) and transversely to the longitudinal axis, before the web is gripped at the web part located adjacent the body. This invention also relates to a body wrapping arrangement.

Abstract: A method and apparatus for coating components such as cutting tools with diamond using a microwave plasma excited gas mixture in a reactor equipped with a bowl-shaped substrate table having a concave inner surface for supporting the components to be coated. The plasma forms a plasma ball during the coating operation and the geometrical shape, configuration and position of the table is adapted to stabilize the plasma and control the shape and position of the plasma in such a way that the outer surface of the plasma conforms substantially to the surfaces of the components to be coated. The table can include a system of channels for optimized gas flow and metallic or ceramic wires or rods to control the shape and position of the plasma as well as yield additional excitation of the gas mixture. The table can include an upper rim which facilitates coupling of the plasma directly to the table. The table can include ledges, rods, compartments and/or holes for supporting the components to be coated.

Abstract: A method for packaging bales with strips of plastic packaging film, in which a bale is rotated about a generally horizontal axis and, when appropriate, about a generally vertical axis, and wherein film is taken from a film magazine spaced from the bale and wrapped around the bale in successive turns while maintaining the film under tension, and wherein the film in each turn of film around the bale extends generally parallel with and transversely to the horizontal axis. The bale is then wrapped with a further wrapping of film such that successive turns of this further wrapping cross-over those parts of the underlying film which extend generally parallel with the horizontal axis in a manner to retain the underlying turns. The film material is held under tension while being applied.

Abstract: A method for packaging bales (1) with strips of plastic packaging film (9), in which a bale is rotated about a generally horizontal axis (3) and, when appropriate, about a generally vertical axis (6), and wherein film is taken from a film magazine (7) spaced from the bale and wrapped around the bale in successive turns while maintaining the film under tension, and wherein the film in each turn of film around the bale extends generally parallel with and transversely to the horizontal axis. The method is mainly characterized in the bale (1) is then wrapped with a further wrapping of film (9), and in that successive turns (9") of this further wrapping cross-over those parts of the turns (9'") of the underlying film which extend generally parallel with the horizontal axis (3), in a manner to retain the underlying turns. This film material is held under tension while being applied. The invention also relates to an arrangement for carrying out the method, and to a bale.
