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

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 fusion draw apparatus includes a pair of engagement rollers. At least one of the pair of engagement rollers includes a circumferential knife edge configured to cooperate with the other of the pair of engagement rollers to thin the edge portion or sever the edge portion from a central portion of the glass ribbon within the viscous zone of the glass ribbon. In further examples, fusion draw methods include the step of thinning the edge portion or severing the edge portion from the central portion of the glass ribbon within the viscous zone.

Fusion draw apparatus and methods

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.

Systems and methods for aligning High Density Array ('HDA') pin plates, substrates and reservoirs with respect to each other. The system includes a flexure having a flexible print head, elongated members flexibly connected off-axis to the system and a pin plate support assembly detachably connected to the flexure allowing the pin plate assembly to adapt its position during a printing operation. The pin plate has alignment ball receptacles on its surface and the reservoir has alignment balls on its surface facing the pin plate. The pin plate is positioned with respect to the reservoir such that each of the alignment balls is located within one of the alignment ball receptacles to achieve the alignment. Once the pin plate is aligned, it is secured to a supporting assembly such as a vacuum bridge, and inking and printing operations are performed.
