摘要： The optical fiber coating device includes a die-support into which is integrated in one piece a grid, the die-support accommodating an entry die and an exit die with the entry die on one side of the grid and the exit die on the other side of the grid. The outside diameter of the die-support on each side of the grid is greater than the outside diameter of the grid, so as to define a chamber which has a large volume when the coating device is placed in its support.

摘要： A method and apparatus for high velocity dual coating optical fibers includes passing the fiber to be coated through an entrance die into a coating reservoir, to which liquid coating material is supplied under pressure. The diameter of the die passage and the pressure of the fluid is sufficient to prevent air from entering the reservoir. The coated fiber is passed through a centering and sizing die wherein the recirculation of excess coating material is controlled to produce centering forces on the fiber at the high fiber velocity, and wherein the initial coating is sized. The fiber is then passed through a second coating reservoir into an exit die which sizes the second coating. Upon leaving the exit die, the coatings are cured.

摘要： A device for coating an optical fiber, for example a glass fiber drawn from a glass preform, comprises a housing (3) with a lengthwise bore (11), into which a nozzle holder (13) containing a receiving aperture (25) is press-fit. An inlet nozzle (33) and an outlet nozzle (43), through which the optical fiber (1) can pass, are press-fit into the receiving hole (25) of nozzle holder (13) at a distance from each other. A coating space for applying a coating material to the optical fiber (1) is located between the inlet nozzle (33) and the outlet nozzle (43). The press-fitting of the nozzles (33, 43) into the nozzle holder (13), and press-fitting the nozzle holder (13) into the housing, achieves better reproducibility of the nozzle (33, 43) positioning when the device is being assembled.

摘要： A tip holder for assembly in a through axial bore of a cross-head die body to hold a die tip in a predetermined position and to control flow of a molten coating material about the die tip and filamentary member which is moved axially through the die for coating purposes. An annular groove is formed about the surface of the tip holder adjacent a radial bore in the body through which the molten material is introduced. In a first embodiment, the annular groove communicates through a plurality of axial grooves in the tip holder with an annular cavity through which the material flows to the die orifice through which the filamentary member and coating material exit the die body. In a second embodiment, the material flows from the annular groove over an annular lip at the forward end of the tip holder. Moreover, both the annular groove and lip are eccentric with respect to the central axis of the tip holder, and compound angles are provided on both the forward and rear sides of the lip, all cooperating to provide an evenly distributed flow of coating material about the cavity preparatory to being deposited on the wire.

摘要： A double-coating cup for applying two protective coatings simultaneously to an optical fiber includes a body having an bore formed therein and provided with a plurality of first and second coating-material inlet channels. A die holder is positioned in the bore in the body and the outer surface of the die holder has first and second slots formed therein positioned opposite the first and second coating-material inlet channels, respectively. The die holder also has first and second radial bores formed therein which communicate with the first and second slots, respectively. A guide die having a bore formed therein is positioned in the bore in the die holder and has a bore formed therein. First and second die nozzles and an intermediate die guide positioned therebetween are disposed in the die holder bore. The first die nozzle is positioned relative to the guide die so as to form a first coating-material slot between facing end faces of the guide die and the first die nozzle, and the second die nozzle is positioned relative to the guide die so as to form a second coating-material slot between facing end faces of the guide die and the second die nozzle. The first die nozzle has distribution channels formed therein which communicate the first radial bores with the first coating-material slot and the second die nozzle includes distribution channels formed therein which communicate the second radial bores with the second coating-material slot.

摘要： Drawn optical fiber is provided with at least one layer of a coating material. The coating material typically is a UV curable material and provides the optical fiber with mechanical and environmental protection. It has been found that the temperature at which the optical fiber is cured has a pronounced effect on the modulus of the cured coating material. In order to provide a coated optical fiber of which the coating material has a desired modulus, the temperature of the coating material during cure is controlled by controlling the amount of energy of infrared wavelength which impinges on the coating material.

摘要： Continuous filament glass fiber bundles are coated with a molten thermoplastic polymer, without the addition of a size to the glass, by passing the filaments through an unpressurized pool of the polymer contained in a passage. The forces between the filaments and the unpressurized polymer interact to center the filaments in the passage as they pass through. The passage is defined by a body member and a detachable cover having contiguous surfaces joined along a longitudinal mating line which is angularly displaced from the longitudinal axis of the passage to assist in prevention of filament snagging in the melting line as they pass through the passage.

摘要： An optical fiber (21) which has been drawn from a preform (22) is moved into and through a chamber (38) of a housing. A source of vacuum is connected to the chamber to prevent the attachment of air pockets to the optical fiber as it is being moved through the chamber and through an opening of a die. The die includes a flow path (55) which is substantially normal to the path of travel of the optical fiber and the die opening is substantially larger than the diameter of the optical fiber. The thickness of the flow path in a direction along the path of travel is sufficiently small so as to prevent the recirculation of the coating material in the vicinity of the point of application to the optical fiber. Also, the fiber draw rate, the pressure of the coating material the direction of the flow path relative to the longitudinal axis of the optical fiber and the diameter of the die opening are such that a gap forms between the coating material and the die. That gap is allowed to be maintained because of the pressure differential between ambient atmosphere an the chamber. As a result, the coating material as it leaves the disc-like flow path and is directed toward the optical fiber is bounded by free surfaces instead of by solid surfaces in the immediate vicinity of where it is applied to the optical fiber. This prevents the development of shear fields and allows the diameter of the coated optical fiber to be varied.
