摘要

A yarn draw-off device for use with a spinning machine includes a pressure roller and a rotatably driven draw-off shaft. The pressure roller is in contact with the draw-off shaft and is rotatably driven by the shaft. An adjustable mounting device is provided for the pressure roller. The pressure roller is rotatably mounted on the mounting device. The mounting device is selectively movable relative to the draw-off shaft so as to vary the contact pressure between the pressure roller and the draw-off shaft.
