A yarn feeding device having a storage body defining a frontal withdrawal rim which forms a yarn braking zone of a yarn brake in co-operation with a circumferentially continuous braking band in the shape of a frustocone jacket and made of a material which is elastically deformable perpendicular to the generatrix of the frustocone. The yarn brake includes a stationary support for the braking band carrier which presses the braking band substantially axially and resiliently against the withdrawal rim. The braking band is held in a floating manner in relation to the withdrawal rim and in relation to the braking band carrier.

[ What is claimed is:] [1.]1. A yarn feeding device including a storage body defining an axis and a circumferentially continuous withdrawal rim disposed in surrounding relation with the axis, a yarn brake including a frusto-conical, circumferentially continuous braking band oriented substantially coaxially relative to said storage body and which together with said withdrawal rim defines a yarn braking zone, said braking band being elastically deformable in a direction substantially perpendicular to a generatrix thereof, and a braking band carrier disposed in mechanical engaging relation with said braking band to press said braking band in the axial direction against said withdrawal rim during operation of said yarn brake, said carrier loosely supporting said braking band to allow same to float relative to both said withdrawal rim and said carrier.
