Abstract (en)

The present invention provides a bunch winding method of catching a spun yarn end of a continuously fed spun yarn 10 and executing bunch winding on an empty bobbin 22, in which the bunch winding is unlikely to fail. A chucker 89 holds the empty bobbin 22 so that a gap (g2) is formed between one end of the empty bobbin 22 and a bobbin holder 86. In this state, a suction pipe 88 in which the end of the continuously fed spun yarn 10 sucked and caught is used to guide the spun yarn 10 to an interior of the gap (g2). Then, in this state, a cradle operating arm 90 allows the empty bobbin 22 to be sandwiched between bobbin holders 85, 86 to sandwich the spun yarn 10 between one end of the empty bobbin 22 and the bobbin holder 86 to nip the spun yarn 10. In this state, the empty bobbin 22 is rotated to form a straight winding on the empty bobbin 22. <IMAGE>
