Flat cable of assembled modules and method of manufacture
First Claim
1. A flat cable comprising a ribbon containing a plurality of modules all having substantially the same external dimensions consisting of a standardized width and a lesser height and being adherently united in edge-to-edge assembly and surrounded by an adherent covering layer of material, each module including one or more signal conductors individually covered with a layer of polyolefin material and embedded non-adherently within a plastic sheath.

Abstract
A flat communication cable is formed of an assembly of standardized modules in edge-to-edge relation surrounded by an overlying polyester protective cover. The modules containing a PVC jacket are united to form a ribbon by a blend of fusion and hot melt adhesive material, and the protective cover is bonded thereto by the adhesive. The modules can contain polyolefin insulated wire pairs, coaxial electrical conductors, stranded or solid wire, fiber optic filaments, or the like. Semiconductive or non-conductive material can be incorporated in the PVC jacket of the modules and/or the adhesive as desired and in any combination. Drain wires can be included. Also, the cover material can include metallic layers for shielding.

25. The method of producing a flat ribbon cable, characterized by the steps of fabricating a plurality of lengths of plastic covered conductors non-adherently sheathed, in turn, with a plastic sheathing material to produce modules all of which have substantially the same external dimensions consisting of a standardized width and a lesser height, assembling selected modules in side-by-side edge-to-edge relationship, surrounding said assembled modules along their length with a covering layer of plastic material, and applying heat and pressure to unite adjacent modules adherently together and to said covering layer.
