<p>In a process for effecting a thread join in an open-end spinning machine the thread, in which a join has been spun and which is drawn off from the spinning apparatus, continues to be discharged, the take-up bobbin being stationary until the thread section with the defect is severed in the course of a thread attachment process, whereupon the thread drawn out of the spinning apparatus is wound onto the take-up bobbin. On the appearance of a defect in the thread, the take-up of the latter on to the bobbin is discontinued, and the thread is then discharged in the above- described way. For this purpose the air throughput of a source of low pressure connected to ducts 22, 31 and 41 is controllable and, when the open-end spinning apparatus comes into operation, can be temporarily increased beyond the air throughput required during a normal spinning process. <IMAGE></p> |
