<p>A method and apparatus for making a cord to be used for reinforcing an elastomeric article such as a tire for a motor vehicle are disclosed. The cord has a core formed by twisting together a group of wires and a series of radially disposed crown layers of wires wound helically about the core or next innermost crown layer side by side and parallel to each other. The apparatus has two machines each having a cage and a shuttle disposed in the cage for winding crown layers from bunches of wires. A device for flexing the wires used to form the crown layers to deform them before winding is included. The two machines are coupled together by a device which determines the relative speeds of rotation of the first and second cages at a 2:1 ratio, respectively.</p> |
