摘要

Apparatus for winding and unwinding a flexible rod, said apparatus including a drum (20) on which the rod (9) is wound, said drum being disposed between two parallel plates (32, 33) and being mounted on a shaft (21) set in spherical bearings (24), said shaft (21) forming an angle of two to eight degrees with the perpendicular to the plane of the drum, the periphery of said drum having a groove which defines, with a band (43) surrounding the end surface of the drum, a volume (44) enclosing the rod, said volume having a rectangular cross-section whose small side is slightly larger than the diameter of the rod. The apparatus has application to driving the components of a telescopic disconnector switch.
