Flexible electrically conductive adhesive tape

A thin, flexible, electrically conductive ribbon-like adhesive tape suitable for do-it-yourself wiring comprising

• (a) a thin paper-like tape backing wound into a roll,
• (b) a pair of spaced apart electrical conductors,
• (c) each of said conductors comprising a multiplicity of electrical wires,
• (d) each of the conductors being a formerly cylindrical bundle of wires and said cylindrical bundle of wires being compressed in the plane of said tape and thereby being at least partially flattened to spread out the multiplicity of wires in the plane of the tape backing such that the tape can be wound and stored in a coil,
• (e) said flattened bundle of wires having a thickness greater than a single wire and the bundle being generally oval or oblate as seen in cross section,
• (f) said compression of the bundle of wires being insufficient to produce a significant loss of strength therein,
• (g) said backing comprising a member selected from the group consisting of paper and flexible plastic resinous sheet materials having electrical insulating properties constructed and arranged to insulate the wires,
• (h) said wires being enclosed within the tape and a layer of pressure sensitive adhesive material on at least the lower surface of the tape to bond the tape to an underlying supporting surface while in use.
