ABSTRACT:
Methods and apparatus are provided for making a laminate which is used to form a corrugated outer shield (60) of a sheath system (50) for a lightguide fiber cable (20). A strip (81) of a corrosion-resistant metallic material having a relatively high elongation, an oxide surface layer (65) and a relatively coarse outer surface is preheated to a temperature within a predetermined range. Afterwards, a composite adhesive strip is brought into engagement with the metallic strip and moved between a pair of rollers (91--91) which are maintained at a first temperature and which causes the strips to be subjected to a predetermined pressure. Then the two strips are moved between another pair of rollers (97--97) which are at a second temperature greater than the first and which subject the strips to the predetermined pressure. The resulting laminate (61) is corrugated by a device (104) and formed into the outer shield (60) about an inner shield (51) which is made of a highly conductive metallic material. An extruder (115) applies a plastic jacket ( 70) about the outer shield and causes the jacket to become bonded through the second adhesive material to the oxide layer.
