ABSTRACT:
Forming metal shield for cable core in which a metal tape is moved along a passline over a concave forming surface which tapers in a downstream direction. A convex rotating roller lying parallel to an adjacent region of the forming surface urges the tape against the concave surface to form the tape into a laterally curved shape. The tape then moves along the concave surface and through an overlapping die to complete the shape of the shield with the tape wrapped around the core with overlapped edges.
