    摘要: Methods and apparatus for controlling glass flow in, for example, a downdraw glass manufacturing process (e.g., the fusion downdraw process) are provided. In certain aspects, the mass, thickness, and/or the temperature distribution of molten glass (40) on the surface of forming apparatus (60) is managed by: (A) constructing a stream-tube mapping between (i) regions (510; FIG. 5A) of a cross-section of a conduit (400) that supplies molten glass (40) to the forming apparatus (60) and (ii) regions (510; FIG. 5B) on the exterior surface of the forming apparatus (60); (B) using the stream-tube mapping to select a temperature distribution for the cross-section that results in a desired mass, thickness, and/or temperature distribution of molten glass (40) on the surface of the forming apparatus (60); and (C) heating and/or insulating the conduit (400) so as to produce a temperature distribution for the cross-section which equals or at least approximates the distribution selected in step (B).

    摘要: The fiber-coating concentricity of a coated optical fiber is controlled by non-axisymmetrically heating the coating material in the sizing die with respect to the z-axis along which the fiber is drawn. By controlling the temperature profile and thus the viscosity profile of the coating material, the amount of coating material applied to each azimuthal position of the fiber is controlled as it exits the sizing die. The apparatus that provides the desired temperature profile can also be employed to control the coating diameter.
