ABSTRACT:
A thread traversing device for a winding unit comprises an endless belt provided with a plurality of drivers and having two runs which run in a traversing region approximately parallel to one another and in opposite directions and form outside the traversing region reverse loops, two pairs of guiding rollers provided for guiding the runs in the traversing region, at least two deviating rollers each provided at one side outside of the traversing region for guiding a respective one of the reverse loops. The guiding rollers of the both runs are arranged near one another so that side surfaces of the guiding rollers of one run face side surfaces of the guiding rollers of the other run. The deviating rollers are arranged skewed to the guiding rollers, and the belt in the region of the reverse loops being twisted to form a spatial belt drive.
