Abstract

Method for controlling a thread joining process having several thread joining steps and occuring by starting a rotor of an open end rotor spinning machine, which includes choosing a narrow limited rotor speed range for the beginning of a starting process of a specific thread joining step, which occurs after a first thread joining step, and selectively starting and finishing thread joining steps in substantially constant given intervals before and after the beginning of the starting process, and an apparatus for carrying out the method.
