Fiber drawing machine and method

Claim 1

IN A MACHINE OF THE CHARACTER DESCRIBED, MEANS FOR PRODUCING A HIGH-VELOCITY, GASEOUS CURTAIN, AND MEANS FOR DELIVERING INTO SUCH CURTAIN A FLOWING MASS OF HEATPLASTIC MATERIAL WHICH IS SOLID UNDER ATMOSPHERIC TEMPERATURES, SUCH MATERIAL BEING DELIVERED INTO SUCH CURTAIN IN THE FORM OF INDIVIDUAL, RELATIVELY COARSE STREAMERS UNDER A VELOCITY SOMEWHAT LESS THAN THE VELOCITY OF THE CURTAIN AND GENERALLY IN THE DIRECTIN OF MOVEMENT OF THE CURTAIN, SAID DELIVERING MEANS SURFACE A STREAM OF MOLTEN RECEIVING ON ITS PERIPHERAL SURFACE A STREAM OF MOLTEN MATERIAL AND THROWNING SUCH MATERIAL SUBSTANTIALLY UNIDIRECTIONALLY THEREFROM, AND A PAIR OF SECONDARY ROTORS INTERPOSED BETWEEN SAID PRIMARY ROTOR AND SAID CURTAIN, TO CONFINE SUCH FLOWING MASS IN A DIRECTION TRANSVERSE TO THE DIRECTION OF FLOW THEREOF, SAID SECONDARY ROTORS BEING DRIVEN RESPECTIVELY IN OPPOSITE DIRECTIONS AND BEING SPACED

Claim 3

THE METHOD OF FIBERIZING MOLTEN MATERIAL WHICH INCLUDES THE STEPS OF DISINTERGRATING A FLOWING BODY OF SUCH MATERIAL INTO A DISCRETE MASS LARGELY COMPOSED OF RELATIVELY COARSE STREAMERS, DISCHARGING SUCH MASS AS A SUBSTANTIALLY UNIDIRECTIONAL, VELOCITY-SUSPENSION STREAM, AND APPLYING AN ACDELERATING FORCE TO INDIVIDUAL STREAMERS OF SUCH MASS, WHILE SO SUSPENDED, THROUGH THE MEDIUM OF A FLUID JET, ORIGINATING IN A REGION BEYOND THE POINT OF SUCH DISCHARGE, TO ELONGATE AND ATTENUATE SUCH STREAMERS.

Claim 4

THE METHOD OF FIBERIZING MOLTEN MATERIAL WHICH INCLUDES THE STEPS OF DISINTERGRATING A FLOWING BODY OF SUCH MATERIAL INTO A DISCRETE MASS LARGELY COMPOSED OF RELATIVELY COARSE STREAMERS, DISCHARGING SUCH MASS AS A SUBSTANTIALLY UNIDIRECTIONAL, VELOCITY-SUSPENSION STREAM, AND APPLYING AN ACDELERATING FORCE TO INDIVIDUAL STREAMERS OF SUCH MASS, WHILE SO SUSPENDED, THROUGH THE MEDIUM OF A FLUID JET, ORIGINATING IN A REGION BEYOND THE POINT OF SUCH DISCHARGE, TO ELONGATE AND ATTENUATE SUCH STREAMERS.
