Claims (8)

  1. Dispositif (10) pour le traitement de surface d'une barre sensiblement ronde (200) comprenant des moyens de support et/ou d'avance (120', 120") et des moyens d'abrasion pour ladite barre (200), dans lequel
    lesdits moyens d'abrasion comprennent un premier support de travail mobile (110') et un deuxième support de travail et/ou opposé mobile (110"), au moins ledit premier support de travail (110') étant pourvu d'une bande abrasive (250', 250") ; lesdits deux supports mobiles (110', 110") étant opposés et, dans un mode de fonctionnement, étant constamment en contact avec ladite barre (200), en interposant en option lesdites bandes abrasives (250', 250"), et en maintenant une distance fixe entre les centres entre lesdits supports mobiles (110', 110"), caractérisé en ce que
    lesdits supports mobiles (110', 110") comprennent chacun un rotor cylindrique (112', 112") ayant un axe de symétrie et de rotation sensiblement parallèle à l'axe de symétrie de ladite barre (200), ladite distance fixe étant la distance entre leurs axes de symétrie, lesdits rotors cylindriques (112', 112") pouvant être déplacés verticalement pour amener, dans un mode de fonctionnement, leurs axes de symétrie en correspondance avec l'axe de symétrie de la barre (200), de sorte que lesdits axes se trouvent dans le même plan, empêchant un traitement asymétrique.
  2. Dispositif (10) selon la revendication 1, caractérisé en ce que lesdits supports mobiles (110', 110"), dans un mode de fonctionnement, assurent la rotation desdites bandes abrasives (250', 250").
  3. Dispositif (10) selon une ou plusieurs des revendications 1 et 2, caractérisé en ce qu'il comprend des moyens de support (130) pour un accouplement avec lesdits supports mobiles (110', 110") ; ledit accouplement formant les pivots de rotation (132', 132") pour lesdits supports (110', 110").
  4. Dispositif (10) selon la revendication 3, caractérisé en ce que lesdits moyens de support (130) comprennent des moyens pour espacer lesdits supports (110', 110") de ladite barre (200) pour modifier ladite distance entre les centres.
  5. Dispositif (10) selon la revendication 4, caractérisé en ce que lesdits moyens d'espacement comprennent une vis de recirculation à billes (140) pour espacer lesdits supports (110', 110").
  6. Dispositif (10) selon la revendication 4 ou 5, caractérisé en ce que lesdits moyens d'espacement comprennent un système pneumatique et/ou un système hydraulique pour commander lesdits supports (110', 110") ; ledit système pneumatique et/ou ledit système hydraulique, dans un mode de fonctionnement, permettant à au moins l'un desdits deux supports (110', 110") d'exercer une pression constante sur la surface de ladite barre (200).
  7. Dispositif (10) selon une ou plusieurs des revendications 1 à 6, caractérisé en ce qu'il comprend en outre des moyens pour le contrôle dimensionnel de ladite barre (200).
  8. Système (500) pour traiter des barres sensiblement rondes, caractérisé en ce qu'il comprend au moins un dispositif pour le traitement de surface desdites barres selon une ou plusieurs des revendications 1 à 7.
