A winding head of a cheese-producing textile machine, having a device for the accurate determination of the length of yarn traveling through a measuring head ( ), and having an evaluating device for accumulating the yarn lengths that have passed. The winding head has a device for determining yarn length portions which are removed in the course of a yarn connecting process. The evaluation device is adapted to subtract the removed yarn lengths from the total length of the yarn ( ) which has passed through the measuring head.

Winding head of a textile machine

A method and apparatus of detecting residual yarn on spinning cop tubes, wherein a spinning cop tube is exposed to a suitable light source; the light reflected by the spinning cop tube is detected by a suitable means, e.g., via a camera or other picture-taking device, and two-dimensional picture signals of the spinning cop tube are generated thereby on the basis of the reflected light detected in order to generate a picture matrix comprising picture data in digital form; and the picture signals thusly generated are evaluated by means of performing an edge filtering of the digital picture data in order to segment image edges corresponding to brightness transitions in the picture matrix, from which the presence of residual yarn on the spinning cop tube can be assessed based on the edge filtering.
