Abstract
A false-twist texturing spindle in which the yarn to be twisted may be automatically threaded in the spindle through a retractable tube that is longitudinally movable between the rollers or discs of the spindle, on an axis coincident with the axis of thread travel. The retractable tube is movable from an inoperative spindle mode, allowing yarn threading, to an operative spindle mode after threading, for yarn twisting.
