Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
111 words
A shielding tape comprising in combination (a) a thin elongated flexible film of material having relatively high electrical resistance insulation characteristics and (b) a thin elongated flexible foil of material having relatively low electrical resistance characteristics and having one surface thereof bonded to one surface of said film (a) and being coextensive therewith, said shielding tape being folded along a longitudinally extending crease, thereby to be doubled in thickness, said thin foil (b) having a thin layer of bonding material disposed on the surface thereof which is opposite to its said one surface bonded to said film (a), whereby a foil-to-foil connection is made by said thin layer of bonding material.
Claim 2
Dependent Claim
111 words
A shielding tape comprising in combination (a) a thin elongated flexible film of material having relatively high electrical resistance insulation characteristics and (b) a thin elongated flexible foil of material having relatively low electrical resistance characteristics and having one surface thereof bonded to one surface of said film (a) and being coextensive therewith, said shielding tape being folded along a longitudinally extending crease, thereby to be doubled in thickness, said thin foil (b) having a thin layer of bonding material disposed on the surface thereof which is opposite to its said one surface bonded to said film (a), whereby a foil-to-foil connection is made by said thin layer of bonding material.
Claim 3
Dependent Claim
139 words
A shielding tape comprising in combination (1) a plurality of folded laminates, each comprising (a) a thin elongated flexible film of material having relatively high electrical resistance insulation characteristics and (b) a thin elongated flexible foil of material having relatively low electrical resistance characterisitcs and having one surface thereof bonded to one surface of said film (a) and being coextensive therewith, each said laminate being folded along a longitudinally extending crease, thereby to be doubled in thickness and bringing the surface of said film (a) which is opposite its said one surface into contact with itself, whereby the surface of said foil (b) forms outer opposite surfaces of said folded laminate and (2) insulation film layers bonded to and coextensive with both the top and the bottom foil surfaces of said plurality of folded laminates arranged fold-to-fold and foil-to-foil.
Claim 4
Dependent Claim
139 words
A shielding tape comprising in combination (1) a plurality of folded laminates, each comprising (a) a thin elongated flexible film of material having relatively high electrical resistance insulation characteristics and (b) a thin elongated flexible foil of material having relatively low electrical resistance characterisitcs and having one surface thereof bonded to one surface of said film (a) and being coextensive therewith, each said laminate being folded along a longitudinally extending crease, thereby to be doubled in thickness and bringing the surface of said film (a) which is opposite its said one surface into contact with itself, whereby the surface of said foil (b) forms outer opposite surfaces of said folded laminate and (2) insulation film layers bonded to and coextensive with both the top and the bottom foil surfaces of said plurality of folded laminates arranged fold-to-fold and foil-to-foil.
