PURPOSE:To speed up the yarn ending operation and obtain a yarn ended part having good shape and sufficient strength, by forming a yarn forming apparatus from a fiber separation pipe, a negative pressure chamber connected to a negative pressure duct and false twisting nozzle. CONSTITUTION:If the spinning is stopped, a drafting device 1, taking off device 3 and winding device 4 are stopped to stop the supply of compressed air to a false twisting nozzle of a yarn forming apparatus 2. A fasciated spun yarn (Y-2) is taken out of a package 45, passed through the false twisting nozzle, and sucked through a negative pressure duct 6. The drafting device 1 is then operated to suck a fiber bundle (Y-1) through a fiber separation pipe of the yarn forming apparatus 2 into the negative pressure duct 6. The winding device 4 is operated, and compressed air is supplied to a false twisting nozzle pipe. The taking off device 3 is operated to entwine the fiber bundle (Y-1) around the core yarn (Y-2), and the aimed fasciated spun yarn is wound onto the package 45. |
