摘要： 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.

摘要： 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.

摘要： 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.

摘要： Converters for producing glass articles from glass tubes include a thermal separating station to separate the glass articles from the working end of the glass tube. Thermal separation forms a meniscus of glass at the working end of the glass tube. Instead of a stationary piercing station to pierce the meniscus, the converter includes an auxiliary processing station disposed directly downline from the separating station, where the auxiliary processing station is a heating station or a forming station. The converter includes a piercing device disposed between the separating station and the auxiliary processing station. The piercing device pierces the meniscus at the working end of the glass tube during the index time as the converter translates the glass tube between the separation station and the auxiliary processing station. Methods of producing glass articles include piercing the meniscus during the index time.

摘要： 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 Wm, a melt thickness Tm and a core to cladding thickness ratio Tc:Tcl. The multi-layer glass melt is directed onto the surface of a molten metal bath contained in a float tank. The width Wm of the multi-layer glass melt is less than the width Wf of 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 Wm of the multi-layer glass melt increases, the melt thickness Tm decreases, and the core to cladding thickness ratio Tc:Tcl remains constant as the multi-layer glass melt solidifies into a laminated glass sheet.

摘要： A forming tool for use during a process of converting a glass tube into a glass container, includes a base portion comprising a fluid cavity for containing a fluid and an insertion portion extending from the base portion. The insertion portion includes an external surface sized to fit into an opening of the glass tube. In embodiments, the insertion portion comprises a fluid opening extending from an interior surface thereof to the external surface, the fluid opening configured to deliver the fluid from the fluid cavity between the insertion portion and the glass tube. In embodiments, the forming tool comprises a thermally conductive insert extending through the base portion and the insertion portion, the thermally conductive insert extending through the fluid cavity such that the fluid in the fluid cavity regulates a temperature of the thermally conductive insert.
