<p>The unwinding feed is for a coil of barbed wire, and comprises two flanges, each equipped with a drum section on its face towards the other, while a shaft passes through it, protruding on both sides. The shaft ends are secured together to support the coil by the drum sections, a space being left between the latter. One shaft end can be hollow, with an internal diameter slightly larger than the external diameter of the other, which fits in it. A lock secures them together to leave a space between the drum sections.</p> |
