ABSTRACT:
Several types of torsion machines are known in the art for electric conductor cables, usually defined as laying machine and operate mechanically either through hydraulic mechanisms or pneumatic mechanisms or both. European patent EP 0844 704 AZ describes a method to manufacture paired cables, through torsion machine with subsequent rotation of at least one of its clamping elements in such a way that the aligned wires are twisted together while they are kept under tension. The rotation clamp can be mounted on a shuttle that can be axially moved with regard to the pairing trajectory between the clamps during the rotation.
The functioning of said machine is characterized because it has a tension element placed on a shuttle that moves in the axial direction of the torsion stretch and because said carriage that moves towards the other tension element is controlled through a predetermined force due to the shortening of the distance of the torsion stretch during the pairing operation.
The applicant has developed an automatic automotive cable pairing or braiding machine that does not require foundation or anchoring to the floor for its installation, that is characterized by the design of its clamping elements actuated by a pneumatic actuator and pneumatic press type pressing device that permit the torsion of the cables with terminal applied at least at one end in previously cut segments, with/without applied terminals providing constant pitches and operating at different combinations of gauges and terminals in said cables.
