Abstract (en)
[origin: EP0764732A1] In a process for making "fancy" threads (15) in a throwing machine by combining tie thread (3') that is twisted from double-twist and/or cabling spindle (12) having reserve (19), with one or more core (2') or finishing (1') threads paired in a situation of dummy twist, wherein using suitable feeders (22, 20) or other means, said core (2') or finishing (1') threads are introduced axially from below into this rotating spindle (12) and are then caused to exit from this spindle (12) in a direction perpendicular to their axis (K-K) and pulled parallel to this tie thread (3'), and the tie thread (3'), core (2'), and finishing (1') threads then are wound, pulling separately on the reserve (19), are twisted together, and are bound to form the fancy thread (15) after they detach from the surface of this reserve (19) to create the body of revolution around this axis (K-K), this "balloon", which is formed by enveloping the positions that are assumed by all these threads (1', 2', 3') when the travel--by rotating around this axis (K-K)--between the reserve (19) and the collecting nozzle (22) of the throwing machine. <IMAGE>
