Abstract (en)
A yarn pooling roller (51) includes a yarn pooling section (52), a first tapering section (58) that widens from a base end section (52a) of the yarn pooling section (52) towards the yarn supplying device side by a first inclination angle (¸1), and a second tapering section (59) that widens from the first tapering section (58) towards the yarn supplying device side by a second inclination angle (¸2) that is smaller than the first inclination angle (¸1). The second tapering section (59) receives the guided spun yarn (Y) and prevents an end of the spun yarn Y from moving towards the tip end section (52b) side of the yarn pooling section (52) at a breakage of the spun yarn Y. The first tapering section (58) guides the spun yarn (Y) received by the second tapering section (59) to the base end section (52a).
