Abstract
A bonded sheath cable (20) includes a core (22) and a longitudinally wrapped outer shield (36) which encloses the core. An outer surface of the shield is provided with a layer (39) of a copolymer adhesive material which causes the shield to bond to an outerlying plastic jacket (41). The shield is wrapped longitudinally about the core to have overlapping portions (51,53) which form a longitudinal seam (38). In order to avoid seam splitting of the jacket along a line aligned with the longitudinal edge (55) of the outer overlapping portion, control means (60) comprising a polymeric material is provided to extend in bicircumferential directions from the longitudinal edge thereby reducing the bond along the overlap seam and allowing the cable to bend and/or twist without causing a stress concentration in the plastic overlying the longitudinal edge.
