Abstract
A yarn braking device includes a resilient annular braking element having provided therein a circumferentially extending braking surface. The braking surface is adapted to be moved into contact with a circular draw-off area of a yarn storage drum under the influence of an axial biasing force. The yarn braking device also includes an annular carrier provided on the braking element, and a stationary Cardan holding device used for supporting the braking element which is movably supported via first and second Cardan axes, and for applying the biasing force thereto. The second Cardan axis is formed of pairs of contact areas provided on the annular carrier on the one hand and on a support ring on the other. The pairs of contact areas are adapted to be detached from one another and to be pressed onto one another by means of the biasing force wherein the support ring is supported in the Cardan holding device such that it is tiltable about the first Cardan axis.
