ABSTRACT:
It is an object of the present invention to provide a spinning device that detects early that fibers F have been accumulated in an air exhausting space55to prevent a defect (weak yarn) in a spun yarn. A spinning device in accordance with the present invention includes a pneumatic spinning nozzle19,a whirling current generating chamber25in which fibers are twisted using a whirling air current generated by the pneumatic spinning nozzle, an air exhausting space55that is in communication with the whirling current generating chamber25,a negative pressure source that sucks air from the air exhausting space55,and a pressure sensor63that detects a pressure in the air exhausting space55.When the pressure detected by the pressure sensor63during a spinning operation performed by the pneumatic spinning nozzle19rises to at least a predetermined value, the unit controller32performs control such that the spinning operation is stopped. The unit controller32further lights an alarm lamp71.
