Abstract (en)
A yarn pooling device (22) includes a yarn pooling roller (41) and a yarn suction device (44). The yarn pooling roller (41) temporarily pools the spun yarn (10) by winding it on its outer circumferential surface. The yarn suction device (44) generates a suction air current at a suction port, which is arranged downstream of the yarn pooling roller (41) in the yarn running direction, to suck and dispose of the spun yarn (10) remaining on the yarn pooling roller (41). When disposing of the spun yarn (10) remaining on the yarn pooling roller (41), the yarn suction device (44) unhooks the spun yarn (10) that is hooked on a yarn hooking member (43) by using a suction pipe (71) and the like.
