<p>: The invention relates to methods and apparatus for the selective manufacture and connectorization of flat cables. In accordance with one preferred flat cable embodiment, two precisely offset arrays of rectangularly shaped conductors are separated by a center film, with each array being adhesively bonded through an associated adhesive coating to only the respectively adjacent one of two outer films. The laminating apparatus includes a first pair of laminating rollers, one being both internally and externally heated, and having a smooth peripheral surface formed of a layer of resilient material, the other having a steel peripheral surface formed with a plurality of specially dimensioned conductor-receiving grooves, and a second pair of finishing rollers, each being unheated and having a smooth, peripheral surface formed of a layer of resilient material. By utilizing a center film with no adhesive coating initially on either side thereof, and the specially constructed laminating apparatus, when used in conjunction with properly chosen laminating pressures, temperatures and feed rate, the resultant fabricated cable exhibits excellent bond strength, and consistently and precisely maintained conductor spacings. In accordance with another aspect of the invention, isolating strips are at least lightly secured on opposite sides of, and extend transversely across, the center film at predetermined spaced terminating points therealong so as to facilitate the termination of the cable, and the subsequent connectorization of the terminated conductor ends thereof to a connector.</p> |
