Abstract (en)
[origin: EP2674378A1] A yarn accumulation device (18) is configured to wind and accumulate a yarn on a yarn accumulation part (37) that is formed on an outer circumferential surface of a yarn accumulation roller (32), the yarn being unwound from the yarn accumulation part (37) in a direction along a rotation axis of the yarn accumulation roller (32). The yarn accumulation device (18) includes a tension applying part (38). The tension applying part (38) is arranged at an unwinding side of the yarn accumulation part (37). The tension applying part (38) is configured to rotate integrally with the yarn accumulation part (37) and in this condition applies a tension to the yarn being unwound from the yarn accumulation part (37). The tension applying part (38) includes a rubber ring (51) made of an expandable elastic material, and an enlarged/reduced portion (50) provided radially inside the rubber ring (51) and configured such that the yarn is nipped between the enlarged/reduced portion (50) and the rubber ring (51). The enlarged/reduced portion (50) is configured to enlarge or reduce its diameter in accordance with the speed of rotation of the yarn accumulation roller (32).
