Abstract

The feeder comprises a stationary drum (12) on which are wound loops of yam to be fed to a downstream textile machine, and a self-governing braking device comprising a hollow, frustoconical braking member (16) which is arranged in front of the drum (12) and is supported at the middle of a spider assembly of springs (18) hooked between the braking member (16) and an annular support (19). The springs (18) have a length at rest which is equal to, or higher than, the span between their hooking point on the frustoconical member (16) and their hooking point on the annular support (19). The annular support (19) is slidably supported with respect to the drum (12) along an axial direction, under control of driving means (22), for biasing the frustoconical member (16) against said edge (12r), thereby causing the frustoconical member to align to the drum, while approaching thereto, by geometrical engagement.
