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.
