  • Apparatus for making a bonded sheath cable
    Patent number: 4622092
    Abstract: A bonded ASP cable includes a multiconductor core which is filled with a waterproofing material. The core is enclosed by a plastic layer (28) which is flooded with a waterproofing material. Wrapped longitudinally about the plastic layer is a corrugated inner shield (31) having a longitudinal seam (35) and having an outer surface covered with a waterproofing material. The inner shield is enclosed by a corrugated outer shield (36) which has an overlapped longitudinal seam (38) and which has an outer surface coated with a layer of an adhesive material. As the outer shield is being formed, a sealant material is introduced into engagement with the inner shield in the vicinity of the longitudinal edge portions of the outer shield. Then as the longitudinal edge portions of the outer shield are overlapped and engaged with each other, the sealant material is caused to flow into cavities between the two shields adjacent to the seam of the outer shield to form a gasket (66).
    Type: Grant
