Abstract
A draw device into which at least two filaments are guided for producing a multi-coloured yarn from differently coloured filaments which consist of a plurality of endless filaments includes a pair of intake rollers for receiving the at least two filaments. Two pairs of drafting system rollers follow the intake rollers to draw the at least two filaments. A texturizing device comprising a texturizing nozzle with a cooling drum is disposed downstream of the two pairs of drafting system rollers to texturize the at least two filaments, wherein at least one yarn is formed from the filaments in the texturizing nozzle. At least one further nozzle is disposed exclusively upstream of the texturizing device in which each filament is separately interlaced. The filaments are drawn on at least one of the two pairs of drafting system rollers at a speed of at least 1,700 m/min.
