Abstract
Automatic winding of yarn on a take-up package of a textile winding machine is controlled with devices including a yarn severing device actuated when the winding is interrupted, a device for sensing the quality of winding of the package, and a processing device that is responsive to a batch change signal which corresponds to an indication of dissimilarity of characteristics between the take-up yarn and the supply yarn. Re-starting of the winding is prevented if the package does not have preset quality characteristics and/or if there is a dissimilarity between the take-up yarn and the supply yarn. Another condition for re-start is the detection by a yarn presence monitoring device that a joined yarn is present, indicating the correction of the yarn interruption after actuation of a yarn joining device.
