摘要： A method and apparatus for sheathing a cable core with a strip of sheathing material are described wherein the strip is crimped with crimping means to give it inherent longitudinal stretchability, stretched to the point where the crimp is substantially removed so that the longitudinal edges of the strip are of substantially equal effective length; and wrapped about the cable core to form a sheath in which the longitudinal edges of the strip overlap. The method and apparatus seeks to overcome the problems of buckling that arise with sheathing material wherein the longitudinal edges of the material are of different length.
