Abstract: A blade, in which at least the composite base structure of the blade is manufactured in a pultrusion process by pulling fibers through at least an impregnation stage and a curing stage, the base structure is equipped with at least one wear area and the said blade is detached from a blade blank formed of a base structure and a wear area. The wear area of the blade is formed of an edge-structure part protruding outside the edge of the base structure.

Abstract: The invention concerns a method for manufacturing a blade (10), in which at least the composite base structure (15) of the blade (10) is manufactured in a pultrusion process (20) by pulling fibers (11) through at least an impregnation stage (12) and a curing stage (14), the base structure (15) is equipped with at least one wear area (16.1, 16.2), and the said blade (10) is detached from a blade blank (22) formed of a base structure (15) and a wear area (16.1, 16.2). The wear area of the blade (10) is formed of an edge-structure part (16.1, 16.2) protruding out side the edge of the base structure (15). In addition, the invention also concerns a corresponding blade and part components for manufacturing a blade according to the invention.

Abstract: The invention relates to a doctor blade for the roll of a paper or board machine and a method for manufacturing the doctor blade. At least one fiber fabric (6a), having its fibers coated with hard particles prior to lamination, is supplied to the vicinity of that surface (4) of the blade which terminates in a cutting edge (2). The particle size is less than 30 ?m. There are typically several fiberglass sheets coated with hard particles and the disposition thereof is such that in the vicinity of blade surfaces, at least in the vicinity of the surface (4) terminating in the cutting edge, the wear resistance is better than in the mid-section of a blade edge (3).

Abstract: A dewatering member for a paper or board machine has a composite body (13) and a hard surface layer (12). The composite body (13) is manufactured in a pultrusion process. An adhesion layer (11) is formed on desired outer surfaces of the composite body (13) such that reinforcements passed to the adhesion layer (11) have been passed to the pultrusion process through a separate resin bath, to which an adhesion improving agent has been added such that the hard surface layer (12) can be applied directly onto it, and reinforcements forming the inner portion of the composite body (13) have been passed to the pultrusion process through a second resin bath. The composite body (13) is coated with a hard coating layer (12) produced by thermal spraying, and the coating (12) is ground.

Abstract: The invention relates to a walking or ski pole used in Nordic walking or skiing. To a prior art pole including a body part (1), a grip part (2), and a tip part (3), is connected a power sensor (6), a user interface (7), and a transmitting device (9) for transmitting the data from the power sensor to the user interface for the purpose of measuring the physiological effect of the pole-assisted exercise and for controlling the exercise performance.

Abstract: A handgrip for a skiing pole and a handstrap fastened to the same, the handstrap including an opisthenar-surrounding strap portion (3) which attaches to a handgrip (1) by way of transmission straps (4, 5) extending under the palm and thumb. The transmission straps (4, 5) are guided inside the handgrip through slots (6, 7) present on opposite lateral surfaces of the handgrip and inclined obliquely downward on the way towards the rear side of the handgrip. Above the slots (6, 7), the strap runs are secured between a wedge-shaped clamping element (8) and the internal walls of a cavity present within the top end of the handgrip.

Abstract: A pushing stick and a ring for the same. The lower end of a shaft comprises a stick ring comprising a fastening part and a projection-like ring frame attached to the fastening part. The bar-like ring frame is directed forwards with respect to the direction of travel and its front is provided with at least one spike. Said spike then resides at a distance from the central axis of the shaft, whereby a bending moment is directed to the ring frame on account of the push force. The ring frame is rigid in order to be able to transmit the bending moment being formed to the lower end of the shaft.

Abstract: The object of the invention is a pole provided with a quick-releasing interchangeable lateral support extension, especially a walking, skiing, alpine skiing or other sports pole. Around the lower end of the pole (1) is injection molded a sleeve socket (2) from which a guide projection (3) and a locking projection (4) protrude. The lateral support extension sleeve (6, 8) includes a resilient tongue (12), below which there is a receiving aperture (14) for the locking projection (4). The sleeve also includes a guide groove (11) for receiving the guide projection (3). The lateral support extension (5) is easy to detach by turning the resilient tongue (12) outwards.

Abstract: An axially extending tubular composite member having a plurality of plies and extending along a longitudinal axis has at least three plies with selectively structured fiber components in each ply. Typically an inner ply has at least one biaxial fiber component, an intermediate ply has at least an axial fiber component that typically is combined with two further fibers to form a triaxial fiber component. Another ply typically has a woven fiber component. A further ply having a biaxial component either replaces the ply of woven fiber or is disposed beneath it over the intermediate ply. A surface veil having fiber and an excess of resin material typically covers at least the innermost or outermost surface of the composite member. An internal web member can be provided, and typically also employs fibers and the matrix material.
