Abstract

APPAREIL A COUPER LES FIBRES, PAR EXEMPLES FIBRES DE VERRE MULTIBRINS, COMPORTANT UN CYLINDRE DE COUPE ROTATIF, MUNI DE LAMES ESPACEES SUR SON POURTOUR, ET DES MOYENS POUR L'AMENEE DE FIBRES ORIENTEES PERPENDICULAIREMENT A L'AXE DE CE CYLINDRE. L'ESPACEMENT UNIFORME DES LAMES 21 EST PLUS FAIBLE SUR UN TRONCON 10A QUE SUR UN TRONCON 10B DU CYLINDRE 10, DE SORTE QUE LE TRONCON 10A COUPE LES FIBRES PLUS COURT QUE LE TRONCON 10B. LES LAMES 21 PEUVENT S'ETENDRE DE PART EN PART DU CYLINDRE 10, LA DIFFERENCE D'ESPACEMENT ETANT OBTENUE EN SECTIONNANT OU EN MEULANT LEURS TRANCHANTS LE LONG DU TRONCON 10B. L'ALIMENTATION EN FIBRES EST ASSUREE PAR PLUSIEURS TUBES CONTENANT DES DISPOSITIFS D'ENTRAINEMENT PAR AIR. L'APPAREIL PERMET DE COUPER SIMULTANEMENT DES FIBRES DE NATURES DIFFERENTES A DES LONGUEURS RESPECTIVES DIFFERENTES.APPARATUS FOR CUTTING FIBERS, FOR EXAMPLES MULTI-STRAND GLASS FIBERS, INCLUDING A ROTATING CUTTING CYLINDER, EQUIPPED WITH BLADES SPACED ON ITS PERIOD, AND MEANS FOR DELIVERY OF FIBERS ORIENTED PERPENDICULARLY AT THE AXIS OF THIS CYLINDER. THE UNIFORM SPACING OF THE BLADES 21 IS LOWER ON A TRUNCON 10A THAN ON A TRUNCON 10B OF CYLINDER 10, SO THAT TRUNCON 10A CUT FIBERS SHORTER THAN TRUNCON 10B. THE BLADES 21 MAY EXTEND THROUGHOUT CYLINDER 10, THE DIFFERENCE IN SPACING BEING OBTAINED BY SECTIONING OR GRINDING THEIR EDGES ALONG THE SECTION 10B. THE FIBER SUPPLY IS PROVIDED BY SEVERAL TUBES CONTAINING AIR-TRAINING DEVICES. THE APPARATUS ALLOWS SIMULTANEOUS CUTTING OF FIBERS OF DIFFERENT NATURES AT DIFFERENT RESPECTIVE LENGTHS.
