THE METHOD FOR PRODUCING A HIGH TEMPERATURE, HIGH VELOCITY, STABILIZED GASEOUS FLAME BLAST FOR HEATING FIBERIZABLE THERMOPLASTIC MATERIAL BEING ADVANCED INTO THE PATH OF THE BLAST, WHICH COMPRISES: (A) DIRECTING A COMBUSTIBLE HOMOGENEOUS ADMIXTURE OF GASES IN A SUBSTANTIALLY UNIFORM ELONGATED RECTANGULAR DISTRIBUTION PATTERN INTO A REFRACTORY TUNNEL THROUGH AN ORIFICE WHICH IS VERTICALLY DISPLACED FROM THE CENTRAL AXIS OF SAID TUNNEL; (B) BURNING SAID ADMIXTURE IN SAID TUNNEL WHILE ADVANCING THE BURNING MIXTURE IN A FLOW DISTRIBUTION PATTERN WHEREIN THE HEAT INTENSITY OF THE BURNING MIXTURE IS GREATER AT THE TOP OF SAID FLOW PATTERN THAN AT THE BOTTOM THEREOF AND THE VELOCITY OF THE BURNING MIXTURE IS GREATER AT THE BOTTOM OF SAID FLOW PATTERN THAN AT THE TOP THEREOF; (C) DISCHARGING THE BURNING MIXTURE FROM SAID TUNNEL AS A BLAST IN A SUBSTANTIALLY UNIFORM ELONGATED RECTANGULAR PATTERN; AND (D) CONTINUOUSY INTRODUCING THE FIBERIZABLE THERMOPLASTIC MATERIAL TO BE HEATED INTO AN UPPER PORTION OF THE DISCHARGE BLAST AND PROJECTING THE HEATED MATERIAL BY THE FORCE OF THE BLAST
