Abstract
Process and apparatus for twisting fibrous material, the process being characterized by being applied especially to bundles of continuous filaments at an extremely high speed by application of a fluid and by forcing a fluid current of a velocity at least half that of the sound and preferably equal to or greater than that of the sound, against the periphery, preferably eccentrically to the shaft of the yarn that moves at high speed while keeping it under a low tension.
