Abstract
A false-twist apparatus has a support defining three generally parallel and radially spaced axes surrounding a central axially extending twisting region. Respective shafts are journaled in this support for rotation about the axes and carry respective staggered sets of axially spaced disks whose rims radially overlap at the twisting region. Yarn eyes above and below the sets of disks are axially aligned with this twisting region so that a yarn to be false-twisted can pass axially through the lower eye, then zigzag along the regions in contact with the disks, and then pass axially out through the other eye. All of the disks are permanently joined and synchronously rotated. A holder displaceable in a straight line on the apparatus support carries a plurality of arms having yarn-pushing tips that can push a yarn to be false-twisted radially into the region. The straight-line motion of the loading arms as well as their axial positions holds the yarn being loaded in out of contact with the outwardly traveling rims of one of the sets of disks while pressing it against the inwardly traveling rims of the adjacent set of disks.
