Apparatus for processing yarn comprising a disc and roller supported at opposite sides of the plane of a pair of running yarns for frictional engagement with the yarns, with the roller rotating in a direction opposite to the direction of movement of the yarns and with the disc free to turn about an axis at its center perpendicular to the plane of the yarns and midway between the yarns so that the disc is adapted to be maintained in a condition of balanced equilibrium by uninterrupted movement of the yarns between the surfaces of the disc and the roller, and to stop the apparatus in the event that it becomes unbalanced.
