摘要： An improved construction of a rotary yarn-distributing cylinder cooperable with a yarn take-up bobbin at the output of an open-end spinning machine or similar textile apparatus is described. The major portion of the periphery of the distributing cylinder is formed by or covered with a smooth material having a high coefficient of friction to promote efficient driving engagement with the adjacent bobbin. The boundaries of the first surface region are separated from the respective edges of the inclined distributing grooves on the cylinder periphery by second surface regions in the form of smooth strips. The strips exhibit a coefficient of friction considerably lower than the coefficient of the material of the first surface region to permit smooth and unretarded payoff of the yarn in the grooves to the bobbin as the cylinder rotates.
