The chuck is mounted on a hollow tube whose axis is collinear with the bore of the chuck.

The chuck is then rotated so as to rotate the first, inner wire. As this inner wire is rotated, the operator trains the second wire thereagainst, thereby yielding a length of coil with the inner wire extending therethrough.

The apparatus and method can be used to produce optical fiber cables, high pressure flexible composite pipes and the like in which the flat ribbons can be wound either within helical grooves formed within the core or about the cylindrical surface of a smooth core.

The table is positioned at an angle to the machine axis so that the stacked filament bundles and separators can be wound about a rotating core by being drawn along the table by the rotating core for staggered and tangential application of the filaments about the core at the downstream end of the table.
