Abstract

Selon ce procédé, on déplace les profilés (5) par rapport à des brosses rotatives en fils métalliques (6, 7, 8, 9) de façon à en éliminer les souillures sous l'action mécanique de ces brosses auxquelles sont soumises les surfaces des profilés. Les salissures ainsi détachées par voie mécanique sont ensuite aspirées (en 14) dans un courant d'air, par une séparation de poussières en deux étapes. Le faible volume de résidus peut alors etre ensaché à la sortie des séparateurs pour etre évacué.According to this method, the profiles (5) are moved relative to rotary brushes made of metal wires (6, 7, 8, 9) so as to remove the stains therefrom under the mechanical action of these brushes to which the surfaces of the profiles. The dirt thus mechanically detached is then sucked (in 14) into an air stream, by a separation of dust in two stages. The small volume of residues can then be bagged at the exit of the separators to be evacuated.
