ABSTRACT:
In an apparatus for manufacturing a fancy yarn, a rotary hollow spindle (2) carries a binding thread spool (3) and, at its discharge end, a false twist element (4). Associated with the hollow spindle (2) at the entry end are feed means having a pair (13) of delivery rolls for at least one core thread (G) and at least one fancy thread (E) which is supplied at higher speed than the core thread (G). In addition, arranged downstream of the false twist element (4) is a pair (5) of take-up rolls for taking up the finished fancy yarn at a lower speed than the supply speed of the fancy thread (E). A central drive motor (M2) drives the pair of take-up rolls (5) by way of belt drives (7, 10, 12) and the pair (13) of delivery rolls by way of a stepless control transmission (11). The feed means comprise a drawing system (S) for the fancy thread (E) comprising a pair (16) of entry rolls, a pair (17) of middle rolls and a pair (19) of exit rolls, and a separate pair (13) of delivery rolls for the core thread. A respective controllable drive motor (M1, M3) is provided for driving each of the hollow spindle (2) and the pair (19) of exit rolls, while a common, controllable drive motor (M4) is provided for the pairs (16, 17) of entry and middle rolls. Instead of using a central drive motor (M2), a respective controllable drive motor may also be provided for respectively driving the pair (5) of take-up rolls and the pair (13) of core thread delivery rolls.
