METHOD FOR OPERATING FLEECE FORMING APPARATUS FOR FORMING BELT-LIKE SPIN FLEECE FROM THERMOPLASTIC SYNTHETIC RESIN ANDFLEECE FORMING APPARATUS

摘要

PURPOSE: To provide a fleece forming apparatus at as low cost as possible and capable of accelerating filament-travelling speed. CONSTITUTION: The spin fleece forming apparatus is provided with a spinning nozzle unit 2, a cooling unit 4, an extrusion unit 6, an intermediate conduit 8 and a fleece discharging unit 9. Additional impact is imparted to a filament curtain 3 in the cooled extrusion unit 6 by a jet-emitting stream of driving air and the yarn-travelling speed is adjusted and set to the desired speed by its fluidization energy.
