Abstract
A yarn feeder including a stationary storage body and a yarn brake having a brake element which axially contacts the storage body. The brake element is embodied by a truncated cone-shaped, thin-walled braking band which is held externally in an elastic, circular retaining membrane joined to a carrier ring that is concentric to the brake band. At least outside the retaining area for the brake band, several areas having a reduced wall thickness are provided in the retaining membrane.
Claims21
A yarn feeding device comprising a stationary storage body and a yarn brake including a ring-shaped braking body held axially against said storage body, said braking body including a frusto-conical and thin-walled braking band having an outer edge region which is held in a holding area of an elastic and annular holding membrane, said holding membrane being connected outwardly of said holding area with an outer carrier ring disposed concentrically to said braking band, said holding membrane defining a plurality of circumferentially distributed portions between said carrier ring and said holding area, and a plurality of spring spokes integrated into said holding membrane with each said spring spoke being disposed between an adjacent pair of said portions, and said portions having reduced wall thicknesses as compared to wall thicknesses of said spring spokes such that said portions respectively define intermediate spaces between adjacent said spring spokes, each said intermediate space being bridged by a membrane layer.
A yarn braking body for a yarn feeding device having a stationary storage body, said yarn braking body comprising a frustoconical and thin-walled braking band having an outer edge region held in a holding area of an elastic and annular holding membrane, said holding membrane being connected outside of said holding area to an outer carrier ring arranged concentrically with respect to said braking band, said holding membrane defining a plurality of circumferentially distributed portions between said carrier ring and said holding area, and a plurality of spring spokes integrated into said holding membrane with each said spring spoke being disposed between an adjacent pair of said portions, said portions having reduced wall thicknesses as compared to wall thicknesses of said spring spokes such that said portions respectively define spaces between adjacent said spring spokes and each said space is bridged by a membrane layer.
