ABSTRACT:
There is provided a spindle device for use in a spinning machine which produces little noise, which can eliminate the need for a rotational drive mechanism for a tubular spindle, for which bearing life is prolonged, and which can prevent waste threads from invading inside the bearings. A tubular spindle accommodated in a housing is rotatably supported by static-pressure pneumatic bearings. A cap, having nozzles and forming a spinning stream of air therein with compressed air blown off through the nozzles, is disposed at the tip portion of the tubular spindle. The tubular spindle radially supported by a film of air blown out through the static-pressure pneumatic bearings is rotated by the spinning stream of compressed air formed in the cap.
