Abstract
A method of inserting a thread through a tube, the stream of the gas carries a thread held in a sealed container forward into and through the tube. The pressure of the gas in the sealed container is kept high enough to maintain the mean flow rate of the gas at any given point of the tube above the travel speed of the thread. A positive longitudinal surging motion is given to the thread advancing through the tube. A frictional force between the flowing gas and the peripheral surfade of the thread, a static pressure working on an area corresponding to the cross-sectional area of the thread, and a difference between the static pressures on both sides of the surging portion of the thread work together to carry the thread forward.
