ABSTRACT:
A method and apparatus for the reeling of a ribbon-like or filamentary material fed to a bobbin winder and wound up in cross winding with precision winding provides for the integrals of the angular velocity (impulses) of the bobbin to be recorded by a first sensor and the integrals of the angular velocity of the drive for the traversing thread guide by a second sensor, the sums of the integrals of the angular velocity to be compared with each other and the drive for the traversing thread guide to be regulated depending on this. The impulses of the first sensor are added in a first allocated counter and the impulses of the second sensor in a second allocated counter during the entire winding operation. The ratio of the sums produced in this way are constantly compared with one or more successively preselectable bobbin ratios and the drive for the traversing thread guide is regulated in such a way that the ratio of the sums of the two allocated counters corresponds to the predefined bobbin ratio or ratios, respectively, during the entire winding operation.
