Zusammenfassung:PROBLEM TO BE SOLVED: To provide a suction nozzle which can reliably capture a yarn end drawn from a package and prevents the captured yarn end from being cut.SOLUTION: A suction nozzle 5 provided in an automatic winder comprises a suction port 6 and a hook part 7. The suction port 6 sucks a yarn end from a package 20. The hook part 7 prevents a yarn end sucked to the suction port 6 from being drawn in an opposite direction of a suction direction. The hook part 7 has tooth row parts 71c, 72c in which a plurality of teeth are aligned in a direction crossing the suction direction in the suction port 6. A plurality of tooth row parts 71c, 72c are disposed at positions different from each other in the suction direction.SELECTED DRAWING: Figure 5 【課題】パッケージから引き出された糸端を確実に捕捉でき、かつ、捕捉した糸端が切れにくい吸引ノズルを提供する。【解決手段】自動ワインダに設けられる吸引ノズル5は、吸引口6と、引掛け部7と、を備える。吸引口6は、パッケージ20からの糸端を吸い込む。引掛け部7は、吸引口6に吸い込んだ糸端が、その吸込み方向とは逆方向に引き出されることを阻止する。引掛け部7は、吸引口6における吸込み方向と交差する方向に複数の歯が並べられた歯列部71c,72cを有する。歯列部71c,72cは、吸込み方向で互いに異なる位置に複数配置されている。【選択図】図5
