摘要： The invention relates to a method for the production of a cutting filament for a device used to cut vegetation such as a strimmer or border cutter. The filament is made of a synthetic material having extended molecular chains. According to the invention (a), the filament (10) is brought to a controlled viscous state, (b) the filament is stretched according to the length thereof in order to perform a first longitudinal molecular orientation (01), (c) a cross-sectional change, resulting in a partial reorientation of molecular chains in a transversal direction (02), is imposed upon the filament, whereupon filaments having multiple molecular orientations are produced, having improved mechanical properties (e.g. a better resistance to tearing).

摘要： A plant or vegetation cutting device which comprises a rotary cutting head and at least one cutting filament or string extending radially from the head, such that upon rotation of the head, the string is extended by centrifugal force and cuts through the plants or vegetation. The string is profiled in a generally uniform manner along its length and it comprises a main body whose width/height ratio is between about 1.2 and 2. A co-extruded cutting appendage may be joined along the leading edge and/or the trailing edge of the main body.

摘要： A cutting unit for a plant or vegetation cutting device and which comprises a rotary cutting head and at least one cutting filament extending radially from the head, such that upon rotation of the head the filament is extended by centrifugal force and cuts through the plants or vegetation. The filament has at least one localized working zone which includes a cutting edge which is defined by two intersecting faces, and the filament is retained by the cutting head in an angular position wherein the cutting edge constitutes the leading edge that engages the plants during operation of the cutting unit. The filament may have a primary or preferred bending plane, and the filament is held in a configuration wherein the filament is bent essentially in the primary bending plane. Also, the localized working zone may be formed of a material which is different from the material of the remainder of the filament.

摘要： This cutting line intended to trim and cut vegetation can be used in rotary-head implements such as brush cutters and edge trimmers. The cutting line consists of a core made of biodegradable and/or photodegradable substance which is covered with a coating or "skin" made of a synthetic substance such as polyamide or polyurethane, forming the exterior surface of the line. Such a line can thus be broken down more rapidly after use, while at the same time retaining excellent mechanical qualities while it is being used.

摘要： The invention relates to a cutting head for a brush cutter, edge trimmer or similar, the head being of the type including at least a passageway for a cutting string and a locking element of the cutting string. The cutting head is characterized in that the locking elements include at least one ratchet wheel, including a toothed wheel mounted in rotation around an axis in such a manner that said teeth project in the passageway. The ratchet can be arranged in such a way that the toothed wheel can turn in a given direction to allow the introduction of the cutting string in the passageway and cannot turn in the opposite direction, thereby locking the cutting string in the passageway.

摘要： The invention relates to a cutting wire (2) which is designed to trim or cut vegetation and which can be used on rotating head devices, such as brush cutters and edge trimmers. The external surface of the cutting wire is provided with tooth-type (5) or similar formations along the length of said wire (2). In the case of a wire having one or more longitudinal cutting edges (4), said tooth-type formations (5) are disposed on the cutting edge(s) along the length of each edge (4). In this way, the sharpness of the wire (2) is improved.

摘要： A cutting head for a brush cutter, edge trimmer or similar, the head comprises a passageway (112) for a cutter string (300) and at least one curved surface (120) for supporting the string, the surface extending between an exit region (115) for said string from said passageway and a peripheral region of the head. According to the invention, the passageway extends (A) in a manner that is offset from an axis of rotation (C) of the head so as to present an inside edge constituted by its edge closest to said axis of rotation, said inner edge corresponding to a trailing edge of the string while the head is rotating, and the curved portion extends from said inner edge. This serves to reduce the radius of curvature of the curved portion without needing to increase the diameter of the head.

摘要： A cutting head for a brush cutter, edge trimmer or similar comprises a plurality of string outlets for a plurality of cutting strings. According to the invention: the axes of the cutting string outlets are distributed in at least two planes (Pac, Pcb) mutually spaced by a distance (H2) greater than or equal to approximately 1.8 times the height (H1) of each string, in each plane the respective string outlets are at the same level, and in all planes the direction of rotation of the head is the same. Chopping of the cut vegetation is therefore promoted.
