<p>A cable winder comprises a frame plate 1 carrying a shaft 2 on which a spring-loaded drum 3 is mounted for rotation, a rotatable speed regulator 8 comprising a hub 9, which is adapted to be driven by a flange 16 of the drum, and a braking mechanism 18 for braking the drum. In order to minimize the number of parts the braking mechanism 18 and the speed regulator 8 are combined to form a single part, in such a way that the braking mechanism acts on the hub 9 of the speed regulator. For this purpose the hub 9 engages in a wedge-shaped gap 20 formed between a brake shoe 19 and the drum flange 16.</p> |
