ABSTRACT:
A device for switching off and switching on the operation of a spindle of a textile twisting or spinning machine having a rumming thread is provided which includes the following elements. A pneumatic switching device is adapted to be operatively connected to a spindle stop mechanism of the textile machine for actuation and de-actuation thereof. A movable running thread sensor device is held in a first normal operating position by the running thread in the textile machine and moves to a second switching position upon breakage of the running thread. A movable breaking sensor device is adapted to be operatively connected to a spindle breaking mechanism of the textile machine for moving between a first position during normal operation of the spindle to a second position upon actuation of the spindle breaking mechanism after thread breakage. Pneumatic control mechanisms are operatively connected to the pneumatic switching device, the running thread sensor device and the movable breaking sensor device for operating the switching device to actuate the spindle stop mechanism upon breaking of the running thread to stop the spindle operation and the de-actuating the spindle stop mechanism upon actuation of the spindle breaking mechanism and before the running thread sensor device has returned to its normal operating position by the running thread during subsequent start-up of the spindle operation.
