  Brevet d'invention 
 EMI1.1 
 TCNDSUSB C32NTeIFVGE MULTIPLE Le principe de la tondeuse centrifuge à couteau affuté tournant sur un axe vertical, étant bien   connu :   la juxtaposition de couteaux rotatifs, décrivant des circonférences distinctes permet, non seulement de multiplier par autant, la largeur de conup- (I) en conservant le même empatement   (2 de   châssis, nais présente de nombreux avantages, pour autant que les éléments suivants soient respectés. 



  A. Les couteaux sont actionnés en prise directe, par des moteurs individuels. 



   Il en résulte qu'à largeur de coupe égale, la puissance globale est inférieure à celle que nécessiterait un couteau unique. En effet, les essais montrent que la somme des puissances des moteurs juxtaposés est, à largeur de coupe égale, inférieure à la puissance d'un moteur unique, actionnant un couteau unique. 



   D'où un rapport favorable ; puissance/largeur de coupe. 



   Il en résulte également un accroissement de la sécurité pour l'appareil et l'utilisateur, en cas de choc mécanioue sur le couteau, par la réduction de l'inertie du système tournant. 



  B. Les moteurs sont mis en mouvement par des commandes séparées, empêchant le démarrage simultané de deux moteurs. 



   Il en résulte une réduction du fusible de protection et de la puissance installée, qui pourra ne dépasser que légèrement la puissance absorbée en régime.

  Patent
 EMI1.1
 TCNDSUSB C32NTeIFVGE MULTIPLE The principle of the centrifugal mower with sharp knife rotating on a vertical axis, being well known: the juxtaposition of rotating knives, describing distinct circumferences allows, not only to multiply by as much, the width of conup- (I) in keeping the same wheelbase (2 of chassis, nais has many advantages, as long as the following elements are respected.



  A. The knives are operated in direct drive, by individual motors.



   As a result, at the same cutting width, the overall power is less than that which a single knife would require. Indeed, the tests show that the sum of the powers of the juxtaposed motors is, at equal cutting width, less than the power of a single motor, actuating a single knife.



   Hence a favorable report; cutting power / width.



   This also results in increased safety for the device and the user, in the event of a mechanical impact on the knife, by reducing the inertia of the rotating system.



  B. The motors are set in motion by separate controls, preventing the simultaneous starting of two motors.



   This results in a reduction in the protection fuse and in the installed power, which may only slightly exceed the power absorbed in operating conditions.
