Method of and apparatus for preforming metal overlap edge with overlap die

摘要

The invention relates to the formation of a metallic shield about a cable core to provide a substantially circular configuration of the shield around the core with an overlapped edge portion of the shield being preformed. The shield is first partially formed about the cable core and thereafter the shield is formed in the substantially circular configuration around the cable core while a portion of the overlying longitudinal edge portion of the shield at the overlap is turned inwardly toward the cable core sufficiently to preclude the edge portion of the shield from protruding disadvantageously into a jacket which is subsequently extruded over the shielded cable core.
