The cantilever stranding frame forms the wire transmission track, so that the wire is reversely transported to the output shaft along the track, meeting the transmission needs of the two strandings.

Driven by the synchronous transmission system, the cantilever stranding frame rotates synchronously with the main shaft of the incoming and outgoing wires, and the wire passes through the stranding plate frame to the sizing stranding wheel section of the incoming shaft for the first stranding process, and the first stranding pitch is completed. At the same time, the wire after the first stranding completes the second stranding process between the sizing stranding wheel on the outlet shaft and the straightening device, so that the wire is stranded again on the basis of the first pitch. Stranded to complete the required pitch of the product. In the whole stranding process, when the main shaft rotates once, the wire material completes a stranding process in two different stranding sections respectively, resulting in two pitches per rotation.
