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.
