Abstract:
A method for determining excess length ratio of a length of communications element disposed in a length of conduit to the length of conduit, the method comprising the steps of:continuously feeding the communications element through an extruder cross-head;continuously extruding the conduit over the communications element;providing an initial mark on the conduit;counting a length of the communications element fed into the extruder cross-head from the time the initial mark is provided on the conduit;providing a subsequent mark on the conduit when the counted length of the communications element fed into the extruder cross-head reaches a predetermined value;measuring a distance between the initial mark and the subsequent mark on the conduit; anddetermining the excess length ratio of the communications element disposed in the conduit to the length of the conduit by comparing the distance between the initial mark and the subsequent mark on the conduit to the counted length of the communications element fed into the extruder cross-head.
