Abstract
A yarn feeder having a storage drum, a bracket fixed to the housing and a controlled yarn withdrawal brake axially displaceably held in the bracket. The yarn withdrawal brake includes a ring-shaped braking body co-operating with a yarn withdrawal region of the storage drum and further includes an outer carrier ring which is displaceable in the axial direction within a predetermined axial clearance defined in a ring-shaped holder. The predetermined axial clearance is defined by axial counter stops, and the holder includes at least one pair of shift drives which act on the carrier ring from opposite directions. At least one side surface of the carrier ring is provided with at least one group of travel stroke adjustment ramps of different axial heights, each of which ramps can be selectively aligned with an axial counter stop of the holder.
