A method of marking an optical fiber includes forming an ink stream, moving an optical fiber over a fiber path adjacent the ink stream, and intermittently deflecting the ink stream with a gas jet so that the optical fiber at least partially enters the deflected ink stream so that the ink from the deflected ink stream forms spaced apart marks on the optical fiber outer surface. An optical fiber marking apparatus is also disclosed that includes payout and take modules that move the optical fiber over the fiber path, a marking unit configured to form an ink stream adjacent the fiber path, and an ink stream deflection device that causes the ink stream to deflect and overlap the fiber path so that ink from the ink stream forms spaced apart marks on the outer surface of the optical fiber.

Apparatus and methods for marking optical fibers using a deflected ink stream

The system and methods for marking an optical fiber with color-coded marks disclosed herein include forming closely spaced multiple ink streams, with at least two of the ink streams having different colors. The optical fiber moves over a fiber path that resides adjacent the ink streams. The fiber path and the ink streams are made to briefly intersect so that the ink streams form on the outer surface of the optical fiber a group of spaced apart individual marks, wherein the group of individual marks constitute a color-coded mark. Repeating this marking process at different times as the fiber moves over the fiber path forms spaced apart color-coded marks along the length of the fiber. Subsequent drying and overcoating of the marks fixes and protects the color-coded marks.

Apparatus and methods for forming colored marks on an optical fiber using multiple ink streams

The apparatus and methods include moving an optical fiber over a fiber path that includes a marking location at which resides a marking unit that dispenses an ink-jet stream. A centering method is performed whereby the optical fiber is incrementally moved in a lateral direction through the path of the ink-stream and the mark number density of marks formed on the optical fiber is measured along with the optical fiber position. A process window is defined by the range of lateral fiber positions over which a target mark number density is formed on a consistent basis. A controller calculates an optimum fiber path position and stores it memory for future reference while also moving the fiber path to the optimum position. The initially wet ink marks are dried and the fiber coated with a transparent protective overcoat to form a coated and marked optical fiber.

Apparatus and methods for accurate high-speed marking of optical fibers

A method of marking an optical fiber is disclosed, wherein the method includes forming an ink stream, moving an optical fiber over a fiber path that resides adjacent the ink stream, and periodically changing the position of the fiber path so that the optical fiber at least partially enters the ink stream so that the ink from the ink stream forms spaced apart marks on the outer surface of the optical fiber. An optical fiber marking apparatus is also disclosed that includes payout and take modules that move the optical fiber over the fiber path, a marking unit configured to form an ink stream adjacent the fiber path, and a fiber positioning device that causes the optical fiber to periodically intersect the ink stream so that ink from the ink stream forms spaced apart marks on the outer surface of the optical fiber.

Apparatus and methods for marking optical fibers using an ink stream

An apparatus for tensioning and threading an optical fiber includes a first roller, a second roller, a belt that wraps around the first and second rollers, and a third roller. The belt may be in direct physical contact with the first and second rollers. The third roller may be movable between an engaged and a disengaged configuration relative to the belt. Alternatively, the first roller, second roller, and belt may be movable between the engaged and the disengaged configuration relative to the third roller. Actuation from the disengaged to the engaged configuration captures an optical fiber between the third roller and the belt.

A glass article having a low level of grainy appearance that can appear to have a shift in the pattern of the grains with changing viewing angle of a display, or 'sparkle.' The glass article&#x2014;which, in some embodiments, is a transparent glass sheet&#x2014;has small-angle-scattering properties and/or distinctness-of-reflected-image (DOI), leading to improved viewability in display applications, especially under high ambient lighting conditions. In some embodiments, the antiglare surface of the glass sheet is an etched surface, with no foreign coating present on the antiglare surface.

The apparatus and methods include moving an optical fiber over a fiber path that includes a marking location at which resides a printer unit. The moving optical fiber has an amount of undamped fiber vibration that can exceed a fiber vibration tolerance at high fiber speeds. The printer unit is configured to dispense ink onto the optical fiber to form wet ink marks along the optical fiber as it moves past the marking location. The wet ink marks are dried and counted for quality control. The marked optical fiber is then covered with an overcoat to protect the ink marks. A position sensor measures an amount of vibration of the optical fiber substantially at the marking location. One or more vibration dampers disposed along the fiber path are used to reduce the fiber vibration below the fiber vibration tolerance. This allows for high-speed marking of the optical fiber.
