  • Method and apparatus for alleviating tight spots in false twist textured yarn
    Patent number: 4231219
    Abstract: A method for alleviating tight spots in false twist textured yarn includes the steps of feeding a thermoplastic multi-filament yarn to a false twister, imparting a false twist to the yarn in one direction, setting the twist to provide a latent torque in the yarn, and thereafter passing the yarn around a tapered flange of a freely rotatable roller to impart a twist in the yarn of a direction opposite to that of the false twist imparted by the twister and of a magnitude sufficient to alleviate tight spots occurring in the yarn during passage through said false twister.

  • Apparatus and process for producing a covered elastic composite yarn
    Patent number: 4226076
    Abstract: A process and apparatus for covering elastic single strand core yarns with a plurality of inelastic cover yarns, such as nylon, is provided. The core yarn is stretched in a controlled manner between a set of feeder rolls and a pair of drawing rolls. Intermediate the feeder and drawing rolls, a thread guide is provided for accommodating the interlacing of a plurality of cover yarn strands with the single strand core yarn passing therethrough. The cover yarn and core yarn are further intertwined with one another at a nip formed at the drawing rolls by way of a slight twisting action applied thereto via a take-up spindle for the resulting composite yarn disposed downstream of the drawing rolls.
