Abstract
An improved moving cavity yarn texturing device is described. One improved feature is a two stage energy tube which provides for more effective filling of the moving cavity by the yarn. The first stage has a cross section with a major axis and a minor axis. The second stage has a cross section with a major axis and a minor axis whose ratio is less than that of the first stage. A second feature is an improved chamber design which employs a channel having a "V" shaped cross section which eliminates snagging of the yarn by the cavity.
