Abstract

SELON L'INVENTION, ON DISPOSE ENTRE DEUX CYLINDRES DE LA ZONE DE PRECARDAGE UN PROFIL SPECIAL DE CONSTITUTION DIEDRIQUE ET DE FORME CONCAVE INCURVEE EN CORRESPONDANCE ET AU VOISINAGE DE LA PERIPHERIE DE CES CYLINDRES. LEDIT PROFIL PERMET L'ELIMINATION DES FIBRES COURTES ET DES IMPURETES LORS DU PASSAGE DES FIBRES DU PREMIER AU SECOND CYLINDRE, AVEC L'AIDE DU FLUX D'AIR ENTRAINE PAR LA ROTATION DU SECOND CYLINDRE.ACCORDING TO THE INVENTION, BETWEEN TWO CYLINDERS OF THE PRECARDING ZONE A SPECIAL PROFILE OF DIEDRICAL CONSTITUTION AND OF A CURVED CONCAVE SHAPE IN CORRESPONDENCE AND NEAR THE PERIPHERY OF THESE CYLINDERS. THESE PROFILE ALLOWS THE ELIMINATION OF SHORT FIBERS AND IMPURITIES DURING THE PASSAGE OF THE FIBERS FROM THE FIRST TO THE SECOND CYLINDER, WITH THE ASSISTANCE OF THE AIR FLOW DRAWN BY THE ROTATION OF THE SECOND CYLINDER.
