Finally, the wire take-up device 17 operates to pull the plurality of steel cords. The extension and retraction of the first retractor 61 drives the position of the corresponding first guide wheel 9 to change. The extension and retraction of the second retractor 62 drives the position of the corresponding first guide wheel 9 to change, thereby adjusting the force acting on the single steel wire. The driving motor 74 drives the pulley 14 thereon to rotate. Under the action of the synchronous belt 15, the other pulley 14 rotates synchronously, thereby driving the support tube 72 to rotate synchronously, thereby performing a twisting operation.
