Abstract
False-twisted yarns are continuously fed to a locking mechanism on a rotating guide wheel. The locking device has a clamping shoe for engaging the yarn, after which the direction of false twist is reversed. Two additional clamping shoes then engage the yarn upstream and downstream of the first clamping point. The first shoe is then retracted to permit the twist between the additional shoes to cancel, and a fluid vortex is used to entangle the yarn filaments, locking the node.
