CUTTING DEVICE FOR AGRICULTURAL MACHINES

The present invention relates to a cutting device (2) for agricultural machines with several knife bar sections (4), which are driven so that they are at least temporarily movable in opposite directions and which extend over the working width of the cutting device (2), the knife blades (6) of which, at the time of a stroke movement of the knife bar sections (4), interact in a scissor-like manner with counter knives attached fixedly to the cutting device (2). In order to keep width of the unmown strip as small as possible or to completely avoid it, in the area of a gap (22) which results in the area of the mutually facing ends (8) of adjacent knife bar sections (4) as a result of the movement of the knife bar sections (4), and which becomes smaller and again larger continuously in accordance with the movement of the knife bar sections (4), a mowing finger (10) is arranged, next to which, in a transverse direction, cutting edges (16) of a knife blade (14) arranged fixedly in the area of this mowing finger (10) are formed, which extend at a slant relative to the forward travel direction (V) of the cutting device (2), so that the cutting edges (16) of this knife blade (14) have a V-shaped arrangement which broadens towards the forward travel direction (V), and, on the outer end faces of the outer knife blades (18), which are attached at the mutually facing ends (8) of adjacent knife bar sections (4), cutting edges (20) are formed, which extend parallel to the forward travel direction of the cutting device (2), wherein a drive (26) of the adjacent knife bar sections (4) has a phase offset of between 80° and 100°. La présente invention concerne un appareil de coupe (2) pour des machines agricoles comportant plusieurs sections de tablier à couteaux (4), qui sont entraînées de sorte à temporairement se déplacer dans des sens opposés et sétendent sur la largeur de travail de lappareil de coupe (2), les lames de couteau (6), en même temps quun mouvement de course des sections de tablier à couteaux (4), interagissent en ciseaux avec les contre-couteaux attachés de manière fixe à lappareil de coupe (2). Afin de tenir la bande non coupée aussi petite que possible ou de complètement léviter, dans la région dun espace (22) qui est le résultat dans la région dextrémités mutuellement opposées (8) des sections de tablier à couteaux (4) comme résultat desdites sections de tablier à couteaux (4), lespace devenant plus petit et plus grand continuellement selon le mouvement des
