US Patent:

40739740, Feb 14, 1978

Filed:

Jul 31, 1975

Appl. No.:

5/600280

Inventors:

Robert V. Albarino - Summit NJ
Sergio Torza - Madison NJ

Assignee:

Bell Telephone Laboratories, Incorporated - Murray Hill NJ

International Classification:

B05D 118
B05D 720

US Classification:

427163

Abstract:

In conventional processes for coating continuous filaments the filament is handled by various mechanical means such as, rollers, pulleys, etc. In the manufacture of, for example, optical fibers, such handling causes unacceptable mechanical damage to the fiber. Mechanical contact of the fiber being manufactured can be avoided by passing the fiber through a capillary wetted with a curable coating liquid. The flow of the coating liquid through the capillary is limited by reducing the pressure of the ambient above the liquid level within the vessel containing the coating liquid.

Appl. No.:

5/701302

Inventors:

Robert Vincent Albarino - Summit NJ
Arthur Clifford Hart - Chester NJ

Assignee:

Bell Telephone Laboratories, Incorporated - Murray Hill NJ

International Classification:

C03B 3702

US Classification:

65 3R

Abstract:

the specification describes coating techniques for glass fiber waveguides that avoid physical contact of the fiber by anything other than the coating solution. The techniques depend on the use of very flexible easily deformable materials for the exit die of flooded die applicators.
