PURPOSE:To bring a head part into contact with the inlet part of air false twist nozzle smoothly, and to make threading easy, by attaching the heat part having a complementary shape to the inlet of the air false twist nozzle, consisting of a material having a low coefficient of friction, through a flexible joint to the tip of a main body of a suction pipe. CONSTITUTION:In the suction pipe 1 for yarn end which is brought into contact with the inlet part 2a of the air false twist nozzle 2 and assist yarn to pass reversely through a thread handling area in the nozzle 2, the heat part 1a having a complementary shape to the inlet part 2a of the nozzle 2, consisting of a material having a low coefficient of friction against the inlet part 2a of it, is attached through a flexible joint to the tip of the main body 1b of the suction pipe in such a way that it can be slanted freely. |
