ABSTRACT:
A false-twist apparatus has three parallel shafts carrying interleaved sets of friction disks interconnected by drive belts for joint rotation; one of these shafts is journaled in a stationary mounting plate while the others are journaled in a carrier pivotally connected with that plate for swinging about a fulcrum offset from the three shaft axes whereby two of the disk sets can be separated to facilitate the introduction of a yarn into the intervening twisting region. A whorl on the carrier-supported shaft nearest the fulcrum is normally driven by frictional contact with a continuously moving tangential belt but is disengaged from that belt in the swung-out position of the carrier so that the disks are arrested during introduction of the yarn.
