Abstract
Devices for false-twist texturing textile filaments are described wherein a twist tube is rotated while magnetically held in a wedge shaped gap between a driven roller and a supporting roller which is rotated by power transmitted thereto predominantly by a rotary driving member in frictional contact with the two rollers. This driving member may be a cylindrical pin in the wedge shaped gap opposite that containing the twist tube and held in the gap by magnetic attraction or repulsion. Alternatively the driving member may be a roller mounted freely to rotate about its axis in frictional contact with roller surfaces on shafts carrying the driving and supporting rollers.
