Abstract
A yarn feeding device having a yarn brake including a wear-proof, radially deformable and frustoconical braking band supported in a braking band carrier. The carrier is held substantially coaxially relative to the axis of a storage body of the yarn feeding device and against a circumferentially continuous withdrawal rim of the storage body. A stationary support and a spring assembly are provided, which spring assembly imparts an essentially axial pre-loading force onto the braking band carrier. The braking band carrier is centered in an axially displaceable fashion at the support by means of a universal joint having at least two mechanically and positively cooperating joint elements. The joint center of the universal joint coincides with the axis of the storage body.
