Abstract

A false twist device has a pair of fixedly positioned spindles whose whorls are driven by a tangential belt and whose friction discs overlap wtih each other and with the friction discs of a swingable spindle mounted on an arm which can be angularly displaced about a pivot axis parallel to the spindle axis but spaced outwardly from the triangle defined by the axes of the spindles.
