CA 2308394
Energy efficient process and apparatus are disclosed for forming migration free glass fiber packages composed of fibers (16) bearing substantially uniform coatings of size composition. Heated air from around the fiber forming bushing (12) is drawn into a chamber (56) through which the glass fibers (16) pass to cause the water or solvent in the applied size to be evaporated. The flow of heated air through the chamber (56) is regulated so as to obtain substantially uniform size application to the fibers (16).
L'invention concerne un procédé et un appareil économes en énergie qui permettent de former des enroulements de fibre de verre exempts de migration composés de fibres (16) recouvertes de façon sensiblement uniforme d'une composition d'apprêt. De l'air chauffé provenant de la filière (12) formant des fibres est amené dans une chambre (56) à travers laquelle passent les fibres de verre (16) de manière à faire évaporer l'eau ou le solvant de l'apprêt appliqué. Le courant d'air chaud qui traverse la chambre (56) est régulé de manière à obtenir une application d'apprêt sensiblement uniforme sur les fibres de verre (16).
