Abstract

A method interrupts yarn production on a spinning machine having at least one spinning point having an inlet for a fiber material and an outlet for the yarn made from the fiber material, and wherein the spinning machine comprises a delivery device for feeding the fiber material into the spinning point, a take-off device for drawing off the yarn out of the spinning point, a winding device for winding up the produced yarn, and a yarn monitoring unit for monitoring at least one yarn parameter. Yarn production is interrupted upon detecting a defined deviation of the monitored yarn parameter from a target value, upon changing bobbins at the winding device, and/or prior to switching off the spinning machine. The feed speeds of the delivery device, the take-off device, and the winding device are gradually reduced to a stop in order to interrupt the yarn production, wherein the reducing takes place such that the end of the produced yarn is located between the outlet of the spinning point and the winding device after the reducing is completed.
