Abstract (en)

A support (34) is adapted to be fixed to an accumulator yarn feeder (10) which is provided with a drum (12) adapted to support a yarn (Y) wound thereon which is adapted to be unwound on demand by a textile machine. A hollow braking member (20) extending around an axis coaxially engages a delivery end (12a) of the drum (12). A braking adjustment mechanism (28) comprises a first threaded element (30) which is connected to the hollow braking member (20) and can be translated axially with respect to the support (34) at the command of a second threaded element (32) which is supported rotatably by the support (34). Elastic means (38), which are functionally interposed between the two threaded elements, bias their threadings to be always mutually engaged on a same side, regardless of the direction of rotation of the second threaded element (32).
