Abstract: The present invention refers to the field of industrial automation, with particular reference to industrial robotics and handling in general. In this field, in the present case, cable chains or sheaths for transporting and containing cables, cable bundles or flexible hoses are particularly relevant, said cables or hoses being led to the robotic or handling systems in which they are used.
