Apparatus can comprise a conduit with at least one slot of a plurality of slots comprising an intermediate length including a maximum width that is less than a maximum width of a first end portion and/or a maximum width of a second end portion of the slot. In some embodiments, methods produce a glass ribbon with an apparatus comprising at least one slot within a peripheral wall of a conduit. In some embodiments, methods are provided for determining a volumetric flow profile dQ(x)/dx of molten material flowing through a slot in a peripheral wall of a conduit. In some embodiments, methods and apparatus provide a slot extending through an outer peripheral surface of a peripheral wall of a conduit that can comprise a width profile d(x) along a length of the slot to achieve a predetermined volumetric flow profile dQ(x)/dx of molten material through the slot.

Apparatus and methods for fabricating a glass ribbon

A forming body of a glass forming apparatus may include a first conduit comprising a first conduit wall and at least one slot in the first conduit wall, and a second conduit disposed above and vertically aligned with the first conduit, the second conduit comprising a second conduit wall and a slot extending through the second conduit wall. The forming body may include a first vertical wall and a second vertical wall extending between an outer surface of the second conduit wall and an outer surface of the first conduit wall at a first side and a second side, respectively, of the forming body. The forming body may include a first forming surface and a second forming surface extending from an outer surface of the first conduit wall and converging at a root of the forming body. Methods of forming a continuous laminate glass ribbon are also disclosed.

Methods and apparatus for forming laminated glass sheets

Methods for producing glass articles from glass tube includes securing a glass tube in a holder of a converter; rotating the glass tube; and passing the glass tube through processing stations, which include at least a heating station and a forming station, to form one or more features at a working end of the glass tube. An active time is an amount of time the glass tube is engaged with a heating element or a forming tool while in a processing station, and an exposure index for the processing station is the rotational speed of the glass tube multiplied by a number of heating elements or forming tools in the processing station multiplied by the active time. An absolute difference between the exposure index and a nearest integer is less than or equal to 0.30, which reduces temperature and dimensional inhomogeneity around a circumference of the glass tube.

Methods to control shape uniformity in glass tube converting processes

Disclosed are apparatuses and methods for non-contact processing a substrate, for example a glass substrate, overtop a gas layer. The support apparatus includes a plurality of gas bearings positioned on a pressure box supplied with a pressurized gas. Some embodiments are directed to a method of supporting and transporting softened glass. The method includes placing the glass in proximity to a gas bearing device having a support surface with a plurality of outlet ports disposed therein. Some embodiments are directed to a glass processing apparatus comprising an air table configured to continuously transport and support a stream of glass and a plurality of modular devices supported by a support structure and disposed above the air table. Some embodiments are directed to a method for flattening viscous glass using a two-sided gas bearing device or a one-sided gas bearing device.

Apparatus and method for processing a glass substrate

A slot orifice design that delivers glass ribbon at a uniform temperature and flow across the slot orifice width is provided. The slot orifice design can include a transition section, a pressure tank, and a slot extension.

Method and apparatus for processing glass

Disclosed is an apparatus and method of making molten glass. The apparatus includes a glass former having a slot orifice design to deliver a glass ribbon. The slot orifice design can include a transition section, a slot extension, and external structural reinforcements. In some embodiments, the orifice opening distance of the slot extension varies along the width of the orifice. In some embodiments, the orifice has an orifice opening distance that is smaller at the center of the slot extension than at the edges of the slot extension, which limits glass flow at the center of the slot extension. Also disclosed is a method of making glass using the disclosed apparatus.

Methods and apparatus for processing glass

According to one embodiment, a method for forming a laminated glass sheet includes forming a multi-layer glass melt from a molten core glass and at least one molten cladding glass. The multi-layer glass melt has a width W, a melt thickness Tand a core to cladding thickness ratio T:T. The multi-layer glass melt is directed onto the surface of a molten metal bath contained in a float tank. The width Wof the multi-layer glass melt is less than the width Wof the float tank prior to the multi-layer glass melt entering the float tank. The multi-layer glass melt flows over the surface of the molten metal bath such that the width Wof the multi-layer glass melt increases, the melt thickness Tdecreases, and the core to cladding thickness ratio T:Tremains constant as the multi-layer glass melt solidifies into a laminated glass sheet.

Methods and apparatuses for producing laminated glass sheets

A method of cooling a glass ribbon formed using a fusion draw process. The method includes forming a glass ribbon using the fusion draw process. The glass ribbon, once formed, passes vertically through a glass transition temperature region. The glass ribbon is directed through a protective plenum at least partially located in a bottom of the draw region. A gas is directed into the protective plenum and vertically along a broad surface of the glass ribbon. The gas is directed out of the protective plenum through at least one outlet slot formed through a sidewall of the protective plenum at no less than about 100 Nm/h.

According to one embodiment, a method for forming a laminated glass sheet includes forming a multi-layer glass melt () from a molten core glass () and at least one molten cladding glass (). The multi-layer glass melt () has a width W, a melt thickness Tand a core to cladding thickness ratio T:T. The multi-layer glass melt () is directed onto the surface of a molten metal bath () contained in a float tank (). The width Wof the multi-layer glass melt () is less than the width Wof the float tank () prior to the multi-layer glass melt () entering the float tank (). The multilayer glass melt () flows over the surface of the molten metal bath () such that the width Wof the multi-layer glass melt () increases, the melt thickness Tdecreases, and the core to cladding thickness ratio T:Tremains constant as the multi-layer glass melt () solidifies into a laminated glass sheet. The invention also relates to the associated apparatus.
