Method of assembling a flat electrical cable

摘要

A flat electrical cable and a modular rotary anvil for assembling a flat electrical cable wherein the flat cable includes an upper and lower layer. The upper layer has ribs protruding along its length that are substantially parallel to one another, and continuous substantially parallel and adjacent seams formed therebetween. Conductors are placed between the upper and lower layers adjacent the seams. The present invention may have upper and lower polyester layers having copper conductors therebetween and the seams ultrasonically welded in order to provide a flat electrical cable for various applications such as incorporation in an automobile clockspring. The modular rotary anvil includes multiple removable and interchangeable segments or inserts which provide the ability to impart a smooth or knurled textured surface pattern to the work-piece. piece. Other inserts include cutting inserts which provide for a seam on the work-piece while a the same time cuts the work-piece along a seam.
