    (57) The device for production of fancy effect yarns comprises a hollow rotating spindle (3) driven by a belt (11) and a false twist spindle (4) driven at an angular speed that is adjustable relative to that of hollow rotating spindle (3).
    The rotary movement of the false twist spindle (4) originates from that of hollow rotating spindle (3) by means for varying the angular speed of false twist spindle (4) relative to that of said hollow rotating spindle (3).
    Said means preferably comprise a countershaft (13) and interchangeable pulleys (14, 15, 16, 17) of different diameter inserted: (14) on hollow rotating spindle (3), (15 and 16) on countershaft (13) and (17) on false twist spindle (4).
