PURPOSE:To enable secure ending and restarting of spinning, by inserting yarn end at the side of a wounding material into a spinning machinery by a pair of piecing rollers and helping the restarting of spinning when end breakge occurs in a bind spinning machinery. CONSTITUTION:When end breakage occurs in a bind spinning machinery wherein the air false twist nozzle 4 is arranged at the downstream just below a drafting part, the yarn end drawn out from the winding material P is kept by a pair of the piecing rollers 22, transported to the outlet D of the nozzle 4, inserted into the yarn path 4b in the nozzle 4 by backlashing of the rollers 22, and introduced into the space between the front rollers 3 of the drafting part. In the operation, the suction pipe 21 for yarn end is preferably used. The back rollers 1 and 1' and the middle rollers 3 and 3' of the drafting part, the fleece F is introduced into the space between the front rollers 3 and 3', and both the front rollers 3 and 3' are closed to restart spinning. At a correct time just after the restarting, the piecing rollers 22 and the front rollers 3 and 3' are rotated normally at the same peripheral speed, to help restarting of spinning. |
