<p>In a device for automatically winding the feeder cable of an electrical appliance on a rotary drum, the hub of the drum rotates about an axis (2) mounted on a frame. A centrifugal brake composed of a wheel (5) rotating within a casing (6) and pivoted on a trunnion (4) integral with the frame (1) near the axis (2) is driven at high speed by the drum (3). The wheel (5) has preferably two balancing weights (12) linked to the hub by means of flexible arms (5.3) integral with the hub. The axis (2) of the drum (3), the hinged pin (4) of the wheel (5) and the casing (6) are advantageously injection molded integral with the frame (1).</p> |
