  • Patent number: 4731500
    Abstract: Disclosed is flexible electrical shielding and a method of making the same for self-adherent assembly to an object to protect the object from electrical fields and static. The shielding comprises a nonconductive strip embraced by a flattened tube of conductive wire netting held in place by a layer of tacky adhesive applied to one exterior face of the netting tube and the adjacent side of the nonconductive strip. Anchorage of the tacky layer is facilitated by using a thermoplastic material and depressing portions thereinto under pressure while the strip is temporarily heat softened. A bare conductor extends along and in contact with the interior of the tube of netting and serves as a grounding conductor for the shielding. The shielding is applied to cabling or an object by spirally wrapping it about cabling, a wire harness or by applying it to the surface of an object to be shielded.
