Abstract

False twisting device arranged for high speed rotation to increase rate of twisting has its ferrule formed by a large dia. tube provided at its ends with twisting bushings journalled intermediates its ends in the nip of a pair of flanged rollers and driven by a further roller disposed at the centre of the ferrule and on the diametrally opposite side of the ferrule.
