APPARATUS FOR PRODUCING FIBROUS MATERIALS FROM THERMOPLAST Russian patent published in 2002 - IPC

FIELD: manufacture of fibrous materials. SUBSTANCE: apparatus is designed for manufacture of fibrous materials from thermoplast by melting thereof for obtaining melt having viscosity approximating viscosity of melt at destruction temperature, with following centrifugal forming and drawing of fibers from melt film falling from edge of diverging cone of open end of reactor. Apparatus has extruder with fiber-forming device positioned on individual frame outside extruder heated zones and mounted on shaft equipped with rotational drive, fiber receiver made in the form of belt conveyor, circulation and gas cleaning system for used gas delivered from protective chamber, where fiber-forming device and belt conveyor are positioned. EFFECT: simplified construction and increased efficiency. 4 cl, 2 dwg
