Abstract

Optical fibers are marked as they move continuously in a flat bundle prior to insertion into a protective envelope by continuously spraying an ink jet in a plane intersecting all the fibers, alternately from one extreme fiber to the other. The inkjet is sprayed in a plane perpendicular to the direction of forward movement of the fibers. The marking device comprises a head for spraying a jet of ink in a plane intersecting all the fibers reciprocating from one extreme fiber of the flat bundle to the other. The spray head moves in a plane perpendicular to the direction of forward movement of the fibers.
