ABSTRACT:
A yarn false twisting apparatus is disclosed which is adapted to produce a crimped composite yarn composed of an S twisted component and a Z twisted component, and wherein the full takeup capacity of the apparatus is utilized. The apparatus includes first and second false twisting units associated with each twisting position, with all of the first units being aligned in a first horizontal row extending along the length of the apparatus, and all of the second units being aligned in a second horizontal row. The two rows may be oriented with respect to each other, and the other elements of each twisting position, so that the paths of travel of the two components have an equal twisting length, and an equal cooling length.
