TWISTING FLYER FOR SINGLE-TWIST CABLE STRANDING MACHINE
A twisting flyer for a single-twist cable stranding machine, which is adapted to rotate about a rotation axis and includes two shoulders connected by crossmembers, and an articulated structure which has in turns a first carriage provided with elements for translation on first of the crossmembers and which supports a guide pulley for a cable, and a second carriage provided with elements for translation on second of the crossmembers, which supports a counterweight for the guide pulley The twisting flyer further includes a first pair of rods which are hinged with one end thereof to the first carriage and with another end to a second pair of rods which are hinged with one end thereof to the second carriage and with another end to the first pair of rods, balancing weights at hinge regions between the first pair of rods and the second pair of rods.

STRANDING MACHINE
In a first embodiment, the invention relates to a stranding machine for wires having two wrap-around rollers having wrap-around tracks arranged on the circumference thereof, whereby the wire can be guided in such a way that the wire runs through the first and second wrap-around tracks preferably in alternation in preferably 8-shaped or 0-shaped wraps. In a second embodiment, the stranding machine has a winding device for winding the wire onto a reel having a laying device that can be moved along a movement axis parallel to the reel axis and having a plurality of rotatably supported deflecting rollers, whereby the wire can be guided in such a way that the wire runs onto and/or from each of the deflecting rollers substantially in the plane of rotation of the deflecting roller. In this way, the produced wire has lower twist and lower torsional stresses, which makes the further processing of the wire, in particular the winding, assembly, crimping, and extrusion of a plastic insulation around the wire easier and which increases the number of possible bending reversal cycles.
