Abstract

L'invention concerne l'usinage et peut s'utiliser pour nettoyer la surface d'articles métalliques de la corrosion, de la battiture, pour lisser les petites aspérités et traiter les soudures. La brosse comprend un corps et des fibres en fil métallique formant ressort disposées en groupe, en touffes ou en forme d'ensemble en une rangée à la circonférence. Le corps est réalisé avec la possibilité de raccordement fonctionnel au dispositif de rotation, et les fibres en question sont montées dans le corps avec une inclinaison. Les fibres ont une inclinaison dans les limites d'un angle aigu par rapport à l'axe vertical qui passe par leur base parallèle à l'axe de rotation et perpendiculaire au plan horizontal. En même temps, les fibres sont inclinées par rapport à la ligne radiale qui va de l'axe central de rotation à la base de la fibre, dans les limites de l'angle obtus avec un sommet situé dans la base, sont situées de manière non parallèle à la ligne radiale et ne sont pas posées sur celle-ci. En fonction de la direction de rotation de la brosse les extrémités libres des fibres peuvent être disposées dans le sens des aiguilles d'une montre ou dans le sens opposé, à gauche ou à droite par rapport à la ligne radiale.
