Abstract
In order to interlace a plurality of textured filaments and produce bundled yarn, a plurality of textured filaments having reverse twists creating opposing torques, of which the bundled yarn is to be formed, are initially subjected to a prescribed degree of tension. The tensioned filaments are then brought together and permitted to relax. Upon relaxing, the textured filaments tend to entangle with each other to form the bundled yarn having a resultant neutral torque. The entanglement is carried out without the need for supplying jets of air to the yarn to force them to tangle together.
