ABSTRACT:
A device for measuring the position of a filament bundle as it is withdrawn ertically from a spinnerette, and blown against for cooling, comprising a source of light disposed adjacent the filament bundle in a plane approximately normal to the withdrawing direction, light detector means disposed at an angle .alpha. relative to the source of light, wherein the angle is sufficiently wide that light from the source of light will not impinge directly on the detector means, and analyzer means to calculate the position of the filament bundle on the basis of the signal issuing from the detector means.
