Abstract
A spinning ring structure for use on a spinning frame comprises a stationary ring fixedly held in place, a rotary ring fitted in the stationary ring coaxially with the stationary ring so as to rotate about its center axis and provided with an annular flange at its upper end, a traveler put on the flange of the rotary ring for traveling along the flange to guide a yarn to a bobbin disposed coaxially with the rotary ring. Openings are formed through a neck portion of the rotary ring, whereby flies produced during the spinning operation by friction between the yarn and the traveler are discharged outside the spinning ring structure through the openings due to centrifugal force.
