ABSTRACT:
The device for feeding yarn in a textile machine comprises a set of feed driving rollers rotating at a speed exceeding the maximum yarn processing speed in the machine, a first yarn brake downstream of the driving rollers, a first swing support upstream of the rollers, a second yarn brake and a second swing support. Each swing support includes a movable member exerting by its weight a tension against the yarn which causes the latter to engage frictionally the driving rollers. The frictional force exceeds the force of the first yarn brake and advances the yarn about a length which is sufficient to cause the moving member of the first swing support to abut against a fixed stop member so that the tension is released from the yarn and the holding friction changes to a sliding friction which is lower than the braking force of the first brake and thus stops the decoiling of the yarn.
