Abstract

A thread-loading device is used in combination with a false-twist apparatus having at least one frame element having an abutment surface turned away from the yarn-twisting region defined by three sets of axially spaced rotatable twisting disks. The thread-loading device has interengaging formations on the frame adjacent the abutment surface and on the support for releasably securing same together. These formations extend radially of the region. Thus the support can be fitted to the frame by being displaced radially toward the region to interfit the formations. A detent is carried in the support and displaceable between a blocking position engaged with the arm in the outer position thereof for preventing movement of the arm relative to the support and a freeing position permitting such movement. Release mechanism linked to the detent has a release element displaceable between a projecting position engageable with and depressable by the abutment surface when the formations are interfitted and a depressed position for displacing the detent into the freeing position only when the release element is in the depressed position. Thus the arm cannot move on the support unless the support is…
