METHOD AND A DEVICE FOR REMOVING THE FAULTY YARN PORTION FROM A WORK STATION OF AN OPEN-END SPINNING MACHINE

摘要

The invention relates to a method for removing the faulty yarn portion at a work station of an open-end spinning machine after the work station is stopped in a controlled manner, particularly after a defect of the spun yarn is detected by a sensor (1) of yarn quality, whereby prior to the request to connect a suction nozzle (2) of a work station for sucking off of the faulty yarn portion the value of the vacuum in the central channel (3) of the vacuum system of an open-end spinning machine is found out and evaluated and the suction nozzle (2) of a work station is connected to the central vacuum channel (3) only after the current capacity of the vacuum source detected is sufficient or only after a sufficiently high vacuum is achieved. The invention also relates to a device for removing the faulty yarn portion at a work station of an open-end spinning machine.
