ABSTRACT:
A stranding machine, particularly for making telecommunication cable, having a cage with feed reels, a take-up reel, and a back-rotation device which includes two eccentric discs journalled eccentrically with respect to each other in a rotatable guide ring. The discs have a plurality of corresponding bores in identical patterns, each pair of corresponding bores having an eccentric shaft journalled in the two bores so that eccentric motion of the discs causes the eccentric shafts to rotate. Each eccentric shaft has a bore for feeding a wire strand through it and a clamping member which rotates with the eccentric shaft for imparting torque to the strand, by driving the guide ring independently of the discs, so that back-rotation can be varied.
