galette device and a second galette unit may be provided downstream of the u201c tangling device u201d 19 as the thread is passed to the winding device 20 the configurations of the devices in the post treatment zone do not bear upon the invention u2014 any suitable processing means and treatment stages may be chosen for influencing the compound thread 21 prior to winding onto the bobbin 23 in the exemplary embodiment of the inventive apparatus illustrated in fig1 three bundles of filaments 13 1 13 3 disposed side by side are spun in the spinnerets 3 1 3 3 each of these bundles has a plurality of filament strands the filament bundles 13 1 13 3 may have different properties preferably the basic polymers of which they are comprised have different colors indeed the basic polymers may have different compositions or may contain different amounts of additives each of the filament bundles 13 1 13 3 is combined to form an individual thread 6 1 6 3 for this purpose the filament bundles 13 1 13 3 are subjected to addition of preparation agents by means of the preparation device 7 and are passed through the thread guides 5 1 5 3 from which the individual threads emerge for further treatment of the individual threads 6 1 6 3 in a first pre treatment stage immediately following the u201c preparation u201d a first whirl tangling is carried out in whirl tangling unit 8 1 for this each individual thread 6 1 6 3 is passed through a whirl tangling nozzle 9 1 9 3 the whirl tangling unit 8 1 has a pressure set point value for the compressed air.
