ABSTRACT:
A method for determining yarn number and thickness deviations for yarn connecting processes in automatic open-end spinning machines includes producing a yarn connection at a yarn connection point, subsequently automatically measuring one of the yarn number, yarn thickness and yarn mass per unit length in a yarn section of limited length upstream of the yarn connection point with the yarn running to produce a measured value, comparing the measured value with a comparison value, and inducing a signal with an indication regarding the spinning unit in the case of a deviation between the measured and comparison values with a predetermined magnitude, and an apparatus for carrying out the method.
