1. A twisting flyer for a single-twist cable stranding machine, which is adapted to rotate about a rotation axis, the twisting flyer comprises:
two shoulders connected by crossmembers, and an articulated structure which is adapted to translate on said crossmembers,
a first carriage which is provided with means for translation on a first of said crossmembers and which supports a guide pulley for a cable,
a second carriage provided with means for translation on a second of said crossmembers, which is adapted to translate in a similar manner and in a diametrically opposite position with respect to said first carriage relative to said rotation axis, said second carriage supporting a counterweight for said guide pulley,
a first pair of rods which are hinged with one end thereof to said first carriage and with another end thereof to
a second pair of rods which are hinged with one end thereof to said second carriage and with another end thereof to said first pair of rods,
balancing weights at hinge regions between said first pair of rods and said second pair of rods, which are adapted to compensate, during the rotation of said twisting flyer, a centrifugal force at said first carriage and at said second carriage.
