ABSTRACT:
Controlling the bending of an overlapping edge portion of a metal shield of a cable core by supporting one side of an edge portion at a position along its feed path and applying pressure against the edge portion immediately downstream of and in a direction opposite to the support. Bending of the edge portion occurs immediately it has passed the support while the support dampers resiliency in the edge portion to prevent or lessen springback. Apparatus for bending is placed immediately upstream of the overlapping die and preferably includes means to vary the applied pressure. Hence, the desired orientation of the bent edge portion is obtainable by varying the pressure dependent upon the actual orientation as the overlapped shield leaves the die.
