Method of controlling production of continuous filaments

Claim 1

IN THE PRODUCTION OF CONTINUOUS FIBERS OF HEAT-SOFTENED MATERIAL SUCH AS MOLTEN GLASS WHEREIN CONTINUOUS FIBERS ARE ATTENUATED AT A PREDETERMINED VELOCITY FROM STREAMS FLOWING FROM A MOLTEN MASS OF THE MATERIAL, THE METHOD OF ESTABLISHING THE MAGNITUDE OF ADJUSTMENT IN TEMPERATURE OF THE MOLTEN MASS NECESSARY TO PRODUCE FIBERS OF DESIRED DIAMETER WITHOUT COMPLEX CALCULATION COMPRISING PLOTTING FOR FIBERS OF DESIRED DIAMETER A TEMPERATURE ADJUSTEMENT CHART FOR SAID MOLTEN MASS CORRESPONDING TO A GIVEN TIME FOR COLLECTION OF A SAMPLE OF SAID FIBER SUCH THAT FOR EACH POSITION OF THE NEEDLE OF SAID WEIGHING SCALE AN INDICATION IS PROVIDED OF THE ADJUCTMENT OF TEMPERATURE OF THE MOLTEN SOURCE NECESSARY TO PRODUCE FIBERS OF DESIRED DIAMETER, COLLECTING A FIBER SAMPLE ATTENUATED AT A PREDETERMINED VELOCITY FOR SAID GIVEN TIME, PLACING SAID SAMPLE OF SAID WEIGHING SCALE AND READING AT THE NEEDLE THE MAGNITUDE OF ADJUSTMENT IN TEMPERATURE OF THE MOLTEN MASS NECESSARY TO PRRDUCE FIBERS OF SAID DESIRED DIAMETER, AND THEN MAKING AN ADJUSTMENT IN TEMPERATURE OF SAID MOLTEN MASS CORRESPONDING TO THE MAGNITUDE READ AT THE NEEDLE TO THEREBY ESTABLISH THE TEMPERATURE NECESSARY TO PRODUCE FIBERS OF DESIRED DIAMETER.
