ABSTRACT:
The invention relates to method and apparatus for measuring and displaying the eccentricity or off-set position with respect to coaxiality of a metallic conductor within an insulating coating during an extrusion process. The measuring apparatus employs a combination of optical and electrically inductive techniques to determine respectively the position of the outer coating of the cable and that of the core within the cable. By relating these positional measurements it is possible to determine the position of the core relative to a desired location namely the coaxial position so that appropriate corrections can be made to the extrusion process to keep the core in that coaxial position.
