METHOD AND APPARATUS FOR PRODUCTION OF FIBERS FROM THERMOPLASTIC MATERIALS, SUCH AS GLASS, ROCK, SLAG OR THE LIKE

摘要

The production of fibers from thermoplastic material, particularly vitreous material in a fluent viscous state, by successively intercepting one or more traveling streams of the material by a series of blades or vanes extending radially from a rotary body. The intercepted segments of the streams are flattened on the blades in sheet form, and are projected from channels formed at the ends of the blades, by centrifugal force, in the form of filaments which are then drawn out into fibers.
