Abstract (en)
In a weft feeder (1) comprising a fixed drum (2) on which a rotating arm (3) winds a weft reserve (RT) whose turns unwind from the drum (2), passing through a terminal thread guide (G) under the control of a braking means (4), an anti-balloon device (5) constituted by a frustum-shaped ring (5a) whose smaller diameter is slightly larger than the diameter of the feeder drum (2); the ring is fitted on the drum and is arranged directly ahead of the braking means (4), and the ring (5a) is connected, by way of pivoting means (6) with controlled rotation, to the structure of the feeder (1) so that it can be inclined at an angle to the longitudinal axis of the drum (2) in order to pass from an active position, in which the ring is at right angles to the axis of the drum (2), to a position for threading the feeder (1), in which the ring is inclined at an angle with respect to the drum axis. <IMAGE>
