SYSTEM AND METHOD FOR CONTINUOULSY PREVENTING FILAMENT BRIDGING BETWEEN ADJACENT DRAW NOZZLES

摘要

A system for continually preventing filament bridging between adjacent draw nozzles in the production of non-woven fabrics comprises a heating element (23), generally in the form of a metal heating wire, which is disposed between adjacent nozzles (4) and is positioned in the path of filaments attempting to bridge the nozzles. The temperature is maintaned at a level high enough above the melting point of the filaments so that they will continuously and instantaneously melt when they contact the heating element.
