Abstract
In the manufacture of an optical fiber cable in which optical fibers are paid out from supply bobbins and inserted into the grooves of a core member by means of an inserting head, a photoelectric optical system is disposed between the supply bobbins and the inserting head to provide signals indicating the position of the optical fibers advancing from the supply bobbins. A control device is connected to the photoelectric system and is responsive to the signals generated therefrom to control the speed at which the optical fibers are paid off from the supply bobbins.
