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

According to one embodiment, a forming body of a glass forming apparatus may include an upper portion with a first forming surface and a second forming surface extending from the upper portion. The first forming surface and the second forming surface may converge at a bottom edge of the forming body. A trough for receiving molten glass may be positioned in the upper portion of the forming body. The trough may include a first weir, a second weir opposite from and spaced apart from the first weir, and a base extending between the first weir and the second weir. At least a portion of a vertical surface of the first weir may curve inward towards a centerline of the trough. Similarly, at least a portion of a vertical surface of the second weir may curve inward towards the centerline of the trough.

Forming bodies for forming continuous glass ribbons and glass forming apparatuses comprising the same

Disclosed herein are apparatuses for producing a glass ribbon, the apparatuses comprising a forming body comprising an upper trough-shaped portion comprising two trough walls and a trough bottom; a lower wedge-shaped portion; a delivery end comprising a first recess; and a compression end comprising a second recess; and first and second supports coupled to the first and second recesses, wherein at least a portion of the first or second support surfaces are non-planar and in continuous contact with at least a portion of the respective first or second recess surfaces. Also disclosed herein are methods for producing a glass ribbon using such apparatuses.

Method and apparatus for isopipe support and sag mitigation

A glass forming apparatus may include a forming body comprising a first forming surface and a second forming surface converging at a root. The apparatus may also include at least one cradle assembly comprising a first contact surface and a second contact surface oriented in a V-configuration. The contact surfaces may be engaged with the forming surfaces. The contact surfaces may impart a holding force to the forming body, the holding force having an upward vertical force component. The forming body may also include at least one end block engaged with an end face of the forming body. The at least one end block may impart a compression force to the forming body in a direction parallel to a length of the forming body and perpendicular to the restraining force component.
