PURPOSE:In inserting yarn end into an air false nozzle in the opposite direction, to carry out insertion of yarn easily, by introducing the yarn end to the outlet of the nozzle with forming an air flow in the nozzle, vibrating further the yarn end. CONSTITUTION:In a bind spinning machinery wherein the air false twist nozzle 4 is arranged at the downstream just below a drafting part, when yarn end is inserted into the false twist nozzle 4 in order to carry out ending by superimposing the yarn end drawn out from the winding material P on fleece fed to the drafting part, a pair of the front rollers 1 and 1' at the lowest downstream of the drafting part are set apart. The suction pipe 24 for yarn end is then brought into contact with the false twist nozzle 4 from the space between them. As an air flow is produced in the nozzle 4, the yarn end drawn out from the package P is introduced into the outlet side b of the nozzle 4 by a pair of the piecing rollers 22, and sent to a yarn path while the yarn end Y is vibrated. In order to vibrate it, the piecing rollers 22 are repeatedly rotated clockwise and counterclockwise little by little, or an auxiliary air flow is sprayed on the yarn end Y horizontally. |
