Device for winding on of synthetic threads has facility whereby RPMs of tacho-rollers are measured and used for control of bobbin mandrel drives in such way that controlling of tacho-roller RPMs is carried out
The device (1) for the winding on of synthetic threads (4a,4b) has at least two bobbin revolvers (7a,7b) each with two bobbin mandrels (9a,9b,10a,10b) each of which in turn have a tacho-roller (6a,6b). The RPMs of the tacho-rollers are measured and are used for the control of the bobbin mandrel drives in such a way that a controlling of the tacho-roller RPMs is carried out, and the active bobbin mandrels have the same RPM and the same directional direction (11a,11b).
