A METHOD FOR OPERATING AN OPEN-END ROTOR SPINNING DEVICE AND AN OPEN-END ROTOR SPINNING DEVICE

摘要

The present invention relates to a method for operating an open-end rotor spinning device (1) with an exchangeable spinning rotor (2) driven by a single motor. In accordance with the invention, the spinning rotor (2) is accelerated from a first rotation speed (n1) to a second rotation speed (n2), and the acceleration time (tA, tB) required for acceleration from the first rotation speed (n1) to the second rotation speed (n2) is acquired and evaluated as an evaluation parameter, or that the spinning rotor (2) is accelerated from a first rotation speed (n1) for a specified acceleration time (tA, tB) and the second rotation speed (n2) reached during this time is acquired and evaluated as an evaluation parameter. The invention further relates to the open-end rotor spinning device (1).
