Title (EN) METHOD AND APPARATUS FOR FORMING MINERAL FIBERS
(FR) PROCEDE ET DISPOSITIF DE FORMAGE DE FIBRES MINERALES
Abstract: front page image
(EN)A method and apparatus for forming fibers from molten mineral material (18) comprising a rotatably mounted spinner (10) having an orificed peripheral wall (16) through which the material (18) flows to form primary fibers (20), and a blower (26) adapted to discharge a flow of gases to further attenuate the primary fibers (20) into a veil of secondary fibers (24), a curved surface (38) being positioned so that the flow of gases follows the contour of the curved surface (38) according to the Coanda effect.
(FR)Procede et dispositif de formage de fibres a partir d'un materiau mineral en fusion (18) comprenant une machine a filer (10) montee de maniere rotative possedant une paroi peripherique (16) presentant des orifices au travers desquels le materiau (18) s'ecoule de maniere a former des fibres primaires (20), et un souffleur (28) adapte a la decharge d'un courant de gaz de maniere a amincir ulterieurement les fibres primaires (20) en un voile de fibres secondaires (24), une surface courbe (38) etant positionnee de maniere a permettre au courant de gaz de suivre le contour de la surface courbe (38) d'apres l'effet de Coanda.
