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 spaceto prevent a defect (weak yarn) in a spun yarn. A spinning device in accordance with the present invention includes a pneumatic spinning nozzlea whirling current generating chamberin which fibers are twisted using a whirling air current generated by the pneumatic spinning nozzle, an air exhausting spacethat is in communication with the whirling current generating chambera negative pressure source that sucks air from the air exhausting spaceand a pressure sensorthat detects a pressure in the air exhausting spaceWhen the pressure detected by the pressure sensorduring a spinning operation performed by the pneumatic spinning nozzlerises to at least a predetermined value, the unit controllerperforms control such that the spinning operation is stopped. The unit controllerfurther lights an alarm lamp
