Abstract (en)

A pneumatic spinning device includes a nozzle block (34) and a hollow guide shaft body (20). The nozzle block (34) is provided with a depressurized suction chamber and a whirling chamber having a greater peripheral length than that of the depressurized suction chamber. The nozzle block (34) is provided with at least one air injecting nozzle (27). The air injecting nozzle (27) injects compressed air from a nozzle opening (27a) opening into the whirling chamber, thereby generating whirling airflow in the whirling chamber. A fiber passage is formed in the hollow guide shaft body (20). Moreover, the hollow guide shaft body (20) is arranged such that a tip end at an inlet of the fiber passage is located within the depressurized suction chamber. The nozzle opening (27a) is located downstream in a feeding direction of a fiber bundle than the tip end of the hollow guide shaft body (20).
