Abstract
A melt spinning apparatus that prevents filaments passing through an unstable area from contacting one another. In a melt spinning method for thinning and solidifying each molten filament F ejected from a plurality of nozzles to obtain a yarn Y comprising a plurality of filaments F, each filament F being thinned is charged to the same polarity, and when the plurality of filaments F are assembled together, charge is eliminated from them. In a melt spinning apparatus,having an unstable area A generated necessarily during the rapid thinning of each filament F between a spinning pack,of an ejecting device,located above and a filament converging portion B located below, a charging device,is provided that charges each filament F to the same polarity between the spinning pack,and an inlet Aa of the unstable area A; also, a static eliminating device,is provided that eliminates charge from each filament F between an outlet Ab of the unstable area A and the filament converging portion B.
