Abstract
Apparatus and method for manufacturing helically wound insulated conductors with filament fillers includes first and second payoff stations for paying off a plurality of insulated conductors and elongate filaments of filler materials. These cable components are guided from the payoff stations to a closing die, and are arranged in positions suitable for twisting into a cable by a double twist machine to form a cable of twisted insulated components forming radially outwardly facing helical interstices each of which is substantially filled with another one of the filaments of filler material. Differential or incremental lengths of filler material are metered upstream of the double twist machine to compensate for the differences in the radial distances of the insulated conductors and filaments of filler material on the center or cable of the axis. In this way, the helical interstices are more fully filled and the resulting cable has an exterior surface with minimal voids so that covering of the resulting cable with an outer elastomeric jacket or coating results in a substantially smoother and aesthetically pleasing cable with minimal surface irregularities.
