Patent ID: 7335837

Claim:
A multi-layer, strip-type screening sheet for electric lines, comprising at least one substrate layer ( 2 , 8 ) of a plastic material; and at least one screening layer ( 3 ) of an electrically conductive material which the substrate layer ( 2 , 8 ) is lined with; the screening layer ( 3 ) having a layer thickness between 5 and 50 μm and being provided with spacing gaps ( 5 ) that interrupt electrical conduction therein in a longitudinal strip direction (Z), with the spacing gaps ( 5 ) extending crosswise of the longitudinal strip direction (Z) and recurring at longitudinal intervals (p), wherein the screening layer ( 3 ) is made of a metal foil which is separated into foil pieces ( 4 ) by said spacing gaps ( 5 ) and wherein a ratio that a spacing-gap width (D) bears to a length (L) of said foil pieces ( 4 ) remaining between said spacing gaps ( 5 ) ranges between 1:5 and 1:25.
