Provided at the yarn outlet end of the coolant tube is a supporting member which has a fixed part with a groove of U-shaped cross-section through which the yarn travels and which extends in the direction of the axis of the coolant-carrying tube, and a movable part provided with air and coolant passages arranged to cover and uncover the groove, according to its position.
