Abstract

Spinning apparatus for carrying out a dry/wet-spinning process includes a spinneret for extruding filaments, a blowing device whereby the extruded filaments may be cooled immediately after being delivered from the spinning holes, a container containing spinning bath liquid, and means for bundling the extruded filaments provided in the spinning bath liquid. Preferably, the same means serves both for bundling and diverting the extruded filaments and is non-rotatable.
