Method of making fiber optical multifibers and devices formed thereof
Abstract
Abstract A long and relatively thin fiber optical multifier structure is formed to a rhomboidal cross-sectional shape so as to achieve maximum packing density of convolutions of a similarly shaped fiber drawn from the structure and machine wound on a drum to form a ribbon of several fiber widths for use in the construction of fiber optical image conducting fiberscopes and the like. The fiber is helically wound with one flat side thereof against the drum using a lead no greater than that of the width of said one flat side and moving parallel to the drum in the general direction of slope, toward the drum, of adjacent sides of the fiber. It is also contemplated that the winding lead be slightly less than said width of the fiber to assure maximum packing density.
