Abstract: The method by which a batch is ended in a spinning machine has an effect on its efficiency. As the rule, the end of a batch is determined according to a preset time, the amount of yarn to be produced, or a preset number of bobbins. In order to end a batch with the greatest possible efficiency, the present invention sets the batch end at a time at which full bobbins have been produced at no greater than 75% of the spinning stations operating in producing the batch. A minimum winding condition to be attained by the bobbins is predetermined prior to the end of the batch. The time still required for attaining the minimum winding condition of the bobbins is determined, and those spinning stations whose bobbins cannot attain the minimum winding condition by the time of the predetermined batch end are shut down.
