Abstract
Abstract Process for manufacturing flat multi-conductor cable having two cable members and peelable internal lamina utilizes a pair of dies which simultaneously align conductors, laminate internal lamina, and extrude external lamina thereon. Each die has a conductor aligning surface with parallel linear conductor-receiving recesses therein and an adjacent extrusion surface. Conductors and internal lamina are drawn between aligning surfaces of mated dies and then between extrusion surfaces where vinyl is extruded through an aperture in each die to form external lamina. A knife-edged die insert adjacent one side of the aligning and extrusion surfaces provides a V-notch in one edge of the cable to facilitate peeling apart cable members for termination to a two-sided connector.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
241 words
A flat multiconductor cable of the type having two adjacent cable members separated by dielectric internal laminas a plurality of flat parallel linear conductors of each said cable member being disposed against respective sides of each said internal lamina and having a precise spacing between adjacent conductors in each cable member as well as between superposed transversely offset conductors of said adjacent cables members through the length of said cable, said conductors having been adhered to each said internal lamina while being drawn through aligning means with said internal laminas; two said dielectric internal laminas with continuous bonding therebetween separating said cable members, each said internal lamina has a first surface and a second surface, said first surfaces being juxtaposed, said second surfaces being disposed against respective cable members, said internal laminas having continuous bonding between said first surfaces thereof and continuous bonding between the second surfaces thereof and adjacent cable members, said continuous bonding between said second surfaces of said internal laminas and said cable members providing greater adhesion than the bonding between the first surfaces of said internal laminas, whereby the cable members may be separated by peeling apart the first surfaces of said internal laminas without disturbing the bonding between the internal laminas and the adjacent cable members; and a dielectric external layer disposed against each said internal lamina to overlie and enclose said conductors, said external layers having been extruded against said conductors and said internal laminas.
Claim 2
