Yarn feeder including an adjustable carrier ring for varying braking effects

A yarn feeder comprising:

• a housing;
• a storage drum supported on said housing and defining an axis;
• a controlled yarn withdrawal brake axially adjustably supported on said housing and including a ring-shaped braking body and a ring-shaped holder associated therewith, said braking body cooperating with a yarn withdrawal region of said storage drum and having a carrier ring, said carrier ring being axially shiftable within said holder within a predetermined clearance defined axially between a pair of counter stops defined on said holder;
• a pair of opposed shift drives disposed on said holder which are respectively engageable with said carrier ring from opposite axial directions for axially shifting said carrier ring between said counter stops;
• and
• said carrier ring having a side surface and at least one travel stroke adjustment ramp disposed on said side surface for adjusting a travel stroke of said carrier ring within said predetermined clearance, said ramp defining a surface which is axially offset relative to said side surface, and said carrier ring being rotatable relative to said holder to align said ramp with one of said counter stops facing said side surface of said carrier ring.
