Yarn texturing apparatus

Claim 1

Apparatus for texturing yarn comprising: means forming a first passage through which yarn to be textured can be directed, said first passage having an inlet and an outlet for the yarn; means forming a second passage of greater cross-sectional area at the outlet thereof than at the inlet, the inlet of said second passage being connected to the outlet of said first passage; conduit means communicating with the inlet of said first passage to introduce a fluid; a first chamber of cross-sectional area greater than the crosssectional area at the outlet of said second passage, said first chamber having an inlet and an outlet, the inlet of said chamber being connected to the outlet of said second passage; a plurality of individual stacked members disposed in said first chamber, said members being free to move in said chamber so as to be displaced by an elongated wad of yarn which is formed in said first chamber when yarn and fluid are passed through said first and second passages into said first chamber, whereby the members exert pressure on the sides of such A yarn wad extending from the inlet to the outlet of said first chamber; a second chamber having an inlet and an outlet, the inlet thereof being positioned adjacent the outlet of said first chamber to receive a yarn wad; a hollow, flexible, tapered retaining member extending between the inlet and the outlet of said second chamber, the crosssectional area of said member at said inlet being greater than the cross-sectional area of said member at said outlet; and a plurality of individual stacked members disposed in said second chamber outside said member to exert a force thereon.
