    摘要： Process for continuously curing an elastomeric jacket on a cable, comprising continuously passing a cable having an uncured elastomeric jacket thereon, encased within an outer temporary mold of heat conductive metallic material, e.g. metallic lead, of sufficient encasing layer thickness for protectively confining and supporting therewithin the elastomeric jacket and cable thereat, through a vulcanizing zone maintained at substantially atmospheric pressure and provided with a heat transfer bath, e.g. a fusible mixture including sodium nitrate, sodium nitrite, potassium nitrate and potassium nitrite, while applying the bath to the cable at a selective bath temperature, e.g. about 400.degree.-500.degree. F., sufficient for vulcanizing the mold encased elastomeric jacket in situ during passage of the cable through the zone whereby to vulcanize the jacket in situ substantially free from stress, damage or disturbance, and with subsequent cooling thereof prior to removal of the mold therefrom.

    摘要： Conventionally co-axial cable is made in a continuous extrusion machine by continuously extruding an aluminum tubular cladding (1) through an annular die and simultaneously continuously introducing a core (4), comprised of a conductive wire surrounded by insulation, through an bore in a mandrel (3). A gap is inevitably present between the outer surface of the core (4) and the tubular cladding (1). To eliminate the gap it is necessary to reduce the diameter of the tubular cladding by swaging or drawing. The present invention disposes of the &wagging or drawing step by compacting the insulation of the core before introduction to the mandrel (3). The insulation then gradually expands to recover its original diameter and fill the cladding which has been extruded to its final diameter.
