Abstract

Procedimento per formare filamenti di vetro impiegando forza centrifuga in cui gas compresso viene iniettato da una posizione vicino ad una parte interna di un telaio di aperture di un bruciatore formante fibre verso una parte di gola di una apertura di scarico del bruciatore ad un angolo acuto rispetto alla direzione di scarico di una corrente di fiamma dalla uscita di scarico, in modo che gas compresso viene mescolato con gas di scarico di combustione in corrispondenza di una porzione di entrata della porzione di gola ed il gas mescolato viene iniettato dalla uscita di scarico del bruciatore in una direzione generalmente parallela alla direzione della generatrice della superficie periferica esterna della parete periferica, trasformando con ciò filamenti primari in filamenti secondari fini.
