Abstract

A pneumatic spinning device includes a nozzle block (134) including a whirling airflow generating nozzle (127) adapted to inject spinning compressed air into a spinning chamber (126) to generate the whirling airflow in the spinning chamber (126), a flow pipe (200) adapted to enable flow of the spinning compressed air to be supplied to the whirling airflow generating nozzle (127), and a spinning switching valve (203) provided to the flow pipe (200) and adapted to permit or shut the flow of the spinning compressed air that flows through the flow pipe (200). A volume inside a first flow pipe (201) is set such that a length of a fiber bundle (10e) at a yarn end of the spun yarn (10) cut by the shut of the flow of the spinning compressed air is a first length.
