Yarn draw-off device for a textile machine producing cross-wound bobbins with a yarn draw-off roller that can be driven by a single motor and an associated pressure roller which is driven via frictional engagement, characterised in that the yarn draw-off roller (10) has a rotationally symmetrical basic member (15) with devices (33), which, during the rotation of the yarn draw-off roller (10) produce an air flow which cools the yarn draw-off roller drive (13).
