Ring spinning machine used in textile industry, has spinning ring whose maximum rotation speed is set less than rotation speed of propelled spinning spindle during spinning process

摘要

The spinning machine (1) has a spinning ring (16) that is rotatably stored in a ring rail (20) of ring spinning portion with respect to spindle axis. A ring runner (17) is rotated by swing thread, during the spinning process. The friction of bearing is adjusted, such that rotation of spinning ring is started from predetermined minimum speed of ring runner. The maximum rotation speed of spinning ring is set less than rotation speed of propelled spinning spindle (5) during the spinning process.
