ABSTRACT OF THE DISCLOSURE The present invention discloses an apparatus for pro- ducing optical fiber cable constructions which basically dispose the optical fibers in a loosely-fitting fashion in respective longitudinal compartments provided by splicing tapes folded or shaped to a designated transverse cross-sectional shape. The loose fitting of the optical fibers overcomes the increased transmission losses and changed transmission bandwidth caused by lateral or compression forces inherently applied to the opti- cal fibers of conventional optical fiber cable constructions. The apparatus disclosed is, more specifically, an apparatus for producing an optical fiber cable having a plurality of optical fibers disposed in a plurality of corresponding compartments defined by a plurality of longitudinally folded splicing tapes, comprising: rotary cage means for providing in a designated special relationship the plurality of optical fibers and the plurality of splicing tapes; folding means disposed adjacent said rotary cage means for folding each splicing tape to a desired cross-sectional shape so as to form a recessed portion; and assemblage die means disposed adjacent the folding means for gathering and stranding the folded splicing tapes with the optical fibers disposed therein.
