  • Patent number: 3968321
    Abstract: The telephone communication cable of this specification has a metal shield formed by bending a sheet of metal at one or both edges so that the portions of the sheet that are folded over one another form a shield of double thickness and the shield has one or both of its edges formed by a continuous extent of folded metal instead of a square edge or fluted edge with a burr along the side of the edge toward which the slitting instrument advanced to make the cut. Air spaces are prevented by filling any clearance between the folded areas of the shield with adhesive. The shield is applied as a D-Screen with the edges off the original strip on the curved part of the D-Screen and away from the group of pairs that are shielded by the D-Screen.
