A glass manufacturing apparatus includes a forming vessel including a first end and a second end. The first end includes a vessel surface defining a recess. The glass manufacturing apparatus includes a compression block positioned within the recess and including a first surface and a contact surface that contacts the vessel surface. The compression block applies a force to the forming vessel. The first surface includes a non-planar shape. The glass manufacturing apparatus includes a support apparatus including a support surface supporting the compression block. The support surface is in contact with a portion of the first surface.

Methods and apparatus for manufacturing a glass ribbon

A glass manufacturing apparatus can include a conduit connected to a delivery vessel and an inlet of a forming vessel. The conduit includes a closed sidewall surrounding a channel extending in a flow direction of the conduit. The closed sidewall is continuous from the delivery vessel to the inlet of the forming vessel to define a closed atmosphere from the delivery vessel, through the conduit, and through the inlet of the forming vessel. The glass manufacturing apparatus can include a heating enclosure including a heating wall and a first heating element. The heating wall surrounds a chamber within which the conduit extends. The first heating element is positioned within the chamber between the heating wall and the conduit to increase a temperature within the channel. Methods for manufacturing a glass ribbon with a glass manufacturing apparatus are provided.

Glass manufacturing apparatus and methods

Described herein are glass forming apparatuses with cooled muffle assemblies and methods for using the same to form glass ribbons. According to one embodiment, a muffle assembly for a fusion forming apparatus may include a muffle frame comprising a back wall, a front wall opposite the back wall, and a pair of sidewalls joining the front wall to the back wall in a closed-loop. At least one first cooling tube may extend through the back wall and the front wall across the closed-loop. At least one second cooling tube may extend through the back wall and the front wall across the closed loop such that the at least one second cooling tube is spaced apart from and parallel with the at least one first cooling tube.

Glass forming apparatuses and methods for making glass ribbons

According to one embodiment, an apparatus for forming a glass ribbon may include a forming wedge disposed in a housing and including a pair of downwardly inclined forming surfaces converging at a root. A plurality of heating cartridges may be positioned in ports of the housing. Each heating cartridge may include a heat directing surface that is oriented at an angle of greater than about 90&#xb0; with respect to a bottom surface of the heating cartridge. The heat directing surface may include at least one heating element positioned adjacent to the heat directing surface. The heating cartridge may be positioned such that the heat directing surface faces the forming wedge and an upper edge of the heat directing surface is positioned above the root to direct heat from the heat directing surface towards the root of the forming wedge.

Method and apparatuses for forming glass ribbons

A glass forming apparatus includes a glass delivery vessel, a forming body with a forming body inlet and a downcomer () between the glass delivery vessel and the forming body. The downcomer includes a downcomer tube () with an inlet end () for receiving molten glass from the glass delivery vessel and an outlet end () for discharging molten glass to the forming body inlet. An upper heating zone () and a lower heating zone () positioned downstream from the upper heating zone () encircle the downcomer tube and a lower controlled atmosphere enclosure () is positioned around and sealed to the downcomer tube () in the lower heating zone (). The lower controlled atmosphere enclosure () includes at least one heating element () for heating molten glass flowing through the downcomer tube within the forming body inlet.

An apparatus and methods for making a glass ribbon includes a forming wedge with a pair of inclined forming surface portions converging along a downstream direction to form a root. The apparatus further includes an edge director intersecting with at least one of the pair of downwardly inclined forming surface portions, and a replaceable heating cartridge configured to direct heat to the edge director and thermally shield the edge director from heat loss. A replaceable heating cartridge is also provided for directing heat to the edge director and thermally shielding the edge director from heat loss.

Methods and apparatuses for reducing heat loss from edge directors

A method for forming a glass sheet with reduced inclusions is disclosed. The method includes flowing molten glass over converging forming surfaces of a forming body positioned within an enclosure. The forming body is heated with a plurality of heating elements separated from the forming body by an inner wall of the enclosure. The temperature Tat the bottom of the forming body is decoupled from the temperature Tat the top of the forming body by an insulating thermal barrier positioned between two adjacent heating elements of the plurality of heating elements such that a change in Tdoes not cause a substantial change in T.

Method and apparatus for minimizing inclusions in a glass making process

An apparatus for forming a glass sheet with reduced zircon inclusions in the glass sheet is disclosed. In one embodiment, the apparatus comprises heating elements distributed vertically between the weirs of a forming wedge and the root of the forming wedge, and wherein a thermal barrier is disposed between adjacent heating elements. A method of using the apparatus is also disclosed.

An apparatus for forming a glass sheet with reduced thermal coupling between upper and lower regions of the apparatus is disclosed. The apparatus allows for temperature changes near the lower regions of the enclosure without a large temperature impact on the upper regions of the enclosure, thereby providing for greater flexibility in setting a temperature profile for a forming body located within the enclosure.

Apparatus for thermal decoupling of a forming body in a glass making process

This disclosure relates to methods and apparatus for controlling glass flow in, for example, a downdraw glass manufacturing process (e.g., the fusion downdraw process). The methods and apparatus are particularly well-suited for use in the manufacture of glass sheets such as the glass sheets used as substrates in display devices, e.g., liquid crystal displays (LCDs).

Glass flow management by thermal conditioning

In the formation of sheet material from molten glass, a cooling tube is positioned in the forming area for directing a flow of cooling gas on discrete portions of the molten glass proximate a draw line or root to control local thickness variations in the sheet and thereby provide a uniform glass sheet thickness across the width of the sheet. The cooling tube is disposed in a pivot member configured to rotate about at least one axis, thereby causing an end of the cooling tube to direct the cooling gas over a wide range of angular positions across a portion of the width of the molten glass flowing over and from a forming body.
