INVENTION: METHOD AND APPARATUS FOR TEXTURIZING YARN INVENTORS: HSIN L. LI, HENDRIKUS J. OSWALD and ALFRED L. LILAND ABSTRACT OF THE DISCLOSURE A tow of continuous fibrous filaments is fed by aspira- tion into a stream of compressible fluid. The stream containing the filaments is directed into contact with a barrier disposed within a chamber at a force sufficient to initiate crimping of the filaments. A major portion of the compressible fluid is separated from the filaments and expelled from the chamber. The filaments are transported through the chamber by continuous movement of a surface therein at sufficient velocity to cause overfeeding of the filaments, whereby the filaments are forced against a mass of the tow and emerge from the chamber in crimped form.
