    摘要： Apparatus can comprise a containment device including a surface defining a region extending in a flow direction of the containment device. A support member positioned to support a weight of the containment device can comprise a support material with a creep rate from 1×10−12 l/s to 1×10−14 l/s under a pressure of from 1 MPa to 5 MPa at a temperature of 1400° C. In some embodiments, the support material can comprise a ceramic material. In some embodiments, the support material can comprise silicon carbide. In some embodiments, a platinum wall can be spaced from physically contacting any portion of the support member. In some embodiments, methods can comprise flowing the molten material within the region in the flow direction while supporting a weight of the containment device with the support member.

    摘要： A control apparatus for controlling a thickness of a substrate, such as a glass ribbon. The control apparatus comprises a laser assembly and a shielding assembly. The laser assembly generates an elongated laser beam traveling in a propagation direction along an optical path. The shielding assembly comprises at least one shield selectively disposed in the optical path. The shield is configured to decrease an optical intensity of a region of the elongated laser beam. The shielding assembly is configured to change an intensity profile of the elongated laser beam from an initial intensity profile to a targeted intensity profile. A desired targeted intensity profile can be dictated by an arrangement of the shield(s) relative to the optical path, and can be selected to affect a temperature change at portions of the substrate determined to benefit from a reduction in thickness.

    摘要： A method of manufacturing a glass ribbon can comprise flowing a glass-forming ribbon along a travel path. The glass-forming ribbon can comprise a first major surface and a second major surface opposite the first major surface. A thickness can be defined between the first major surface and the second major surface. The method can comprise heating the first major surface of the glass-forming ribbon at a target location of the travel path while the glass-forming ribbon is travelling along the travel path. The heating can increase a temperature of the glass-forming ribbon at the target location to a heating depth of about 250 micrometers or less from the first major surface. The method can comprise cooling the glass-forming ribbon into the glass ribbon. Prior to the heating, the glass-forming ribbon at the target location can comprise an average viscosity in a range from about 1,000 Pascal-seconds to about 1011 Pascal-seconds.

    摘要： Disclosed herein are apparatuses and methods for drawing sheet glass. More particularly, one or more sets of edge rolls can be configured to have a rotation axis angled away from a line orthogonal to the direction of flow of a ribbon of glass and positioned so as to contact the glass in the viscous region of the draw. Through control over the orientation and position of the one or more sets of edge rolls, sheet width attenuation may be eliminated, thickness of the beads that form along the edges of the glass sheet may be reduced, and instabilities associated with sheet width variation may be eliminated.
