ABSTRACT:
Fiber sheaths are drawn between a pair of drawing cylinders and continuous filaments are introduced upstream of the drawing cylinders to form two strands which are twisted together at a convergence point upstream of a winding mechanism. The tension of the strands is regulated, the strands are wound to form a filament, and the filament thus formed is retwisted on a spinning jenny.
