Title: Apparatus and method for manufacturing optical conductor
Inventor: REMII BURIYUTSUGUMAN
IPC: G02B6/44
Filed: 1987-07-02
Abstract: A grooved cylindrical core or rod is conveyed in a state of elastic elongation, giving it excess length, through a distributing device and a die-plate. Optical fibers are each fitted in a respective groove of the rod at the entry of the die-plate. Downstream from the die-plate, the rod provided with the fibers passes through a zone in which there is a powerful electric field created by a ionization bar. Under the influence of the ionization, the fibers cling to the walls or bottoms of the grooves. This provides the drag necessary for stretching the fibers when they approach the rod.
