Abstract
Apparatus for manufacturing ribbon cable having a plurality of filamentous elements comprises a wheel having a circumferential surface interrupted by a plurality of parallel grooves in which the elements are seated over a common arc. Elements are supplied tangentially toward the wheel as the wheel is rotated and plastic is extruded at a point on the common arc to form a ribbon cable with elements exposed where they lay in the grooves. Elements are entrapped in cable by plastic bridges formed in lateral channels or recesses which interrupt the grooves and permit plastic to flow around elements, by fiber mat which the plastic impregnates, by melt-bonding to plastic insulated wire, by adhesive, or by nearly complete entrapment of elements resulting from a shallow groove profile. An additional layer of plastic may be extruded onto the cable so produced to yield a conventional fully insulated ribbon cable, or for some cable profiles the cable may be mated to like cable for a close centerline spacing of elements.
