Abstract

A braking means (15') for self-adjusting thread braking devices (14) of weft feeders which comprises a first frustum-shaped body (150), which is substantially flexible both radially and axially, and a second frustum-shaped body (151) which is fitted over the first one and is arranged axially only in the region downstream of the drum of the feeder, over a portion (T) having a suitable length, and is adapted to give the portion of the body of the braking means (15') the rigidity that is necessary and sufficient to transmit to the region of tangency of the body with the drum of the feeder the action applied by the elastic means which press on the braking means (15').
