ABSTRACT:
A device and method for wrapping a wrapping material to form S-shaped shields around a cable core of two side-by-side core units in which two tubes are provided for passage of the core units. A space between the tubes accepts the thickness of a central region of the wrapping material which has side portions extending away from the central region. Concave turning surfaces extend partially around the tubes and approach each other as they extend towards an outlet end of the tubes. The core units pass along the tubes and the wrapping materials passes along between the tubes while the turning surfaces progressively turn the side portions inwardly towards and around the tubes whereby the side portions are turned around the core units when these emerge from inside the tubes. In a practical arrangement, the turning surfaces are formed by the inside surface of a frusto core.
