Abstract
A method of, and apparatus for, consecutively controlling the operating conditions at a plurality of spinning positions or locations of a ring spinning machine, wherein there are detected yarn breakages and lap-up formations on rolls of the drafting arrangements. Upon detection of a yarn breakage at a predetermined spinning position the suction air stream of the suction system at such spinning position is rendered ineffectual at such spinning position of the ring spinning machine and such spinning position is checked for the presence of a fiber stream.
