ABSTRACT:
Methods and apparatus of this invention are used to maintain a predetermined arrangement of stranded multi-conductor pair cable units (23--23) within a first group (24) of units while controlling the formation of a laminate (30) comprising a plastic-coated metallic strip (31) into an internal shield which is disposed between the first group and a second group (26) of the units. A device (100) is interposed between faceplates (71, 82) through which the units and the strip are advanced prior to their advance through closing dies (131, 132) and apparatus which encloses the core with a sheathing system. The device controls the formation of the internal shield from the strip and is effective to prevent any buckling of the strip as it is formed into a configuration having arcuate end portions that partially enclose the groups of the units.
