Abstract

L'invention concerne un dispositif pour la coupe d'un tube en matériau semi-rigide. Le dispositif comporte une lame plate, des mâchoires délimitant entre elles un conduit longitudinal propre à recevoir et à pincer le tube sur un maximum de sa périphérie, lesdites mâchoires présentant une fente coupant le conduit transversalement sur la totalité de sa périphérie transversale, et des moyens pour animer la lame et les mâchoires d'un mouvement relatif tel que la lame pénètre dans la fente et que son tranchant traverse transversalement le conduit en coupant le tube, jusqu'à ce que le plat de la lame occupe la totalité de la section transversale du conduit au niveau de la fente en isolant de façon étanche, par son plat, les deux parties du tube coupé. Application à la coupe des tubes utilisée dans les techniques de centrifugation.
