摘要：
A slip-proof elastic yarn-feeding ring device removably fitted to the circumference of a yarn-feeding drum whereby a yarn is pressed between a yarn-feeding belt and the ring device and steadily forward carried by the yarn-feeding belt without slipping movement. The diameter of the ring device is smaller than that of the yarn-feeding drum so that when the ring device is extended to ring the yarn-feeding drum, the ring device closely binds a portion of the circumference of the yarn-feeding drum via its elastic binding force.
