摘要:
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.

The present invention relates to a process for manufacturing flat sheets of a glass-based material and to a device associated with the process. The process comprises delivering the glass-based material (10) from a delivery system (16) to a reservoir (24) between two porous walls (12), the reservoir having a vertical length (L), a horizontal width (W) between side edges (22, 22′ of the walls and including a gap (14) between the walls which varies along the vertical length of the reservoir, the material being separated from the walls by a gas film (28), drawing the glass-based material in a sheet from an outlet of the reservoir, and wherein a flow of the glass-based material delivered to the reservoir is varied across the width of the reservoir, or wherein the gap (14) varies across the horizontal width (w) of the reservoir (24)

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.

According to one embodiment, a method for forming a laminated glass sheet includes forming a multi-layer glass melt (300) from a molten core glass (106) and at least one molten cladding glass (126). The multi-layer glass melt (300) has a width Wm, a melt thickness Tm and a core to cladding thickness ratio TC:TCl. The multi-layer glass melt (300) is directed onto the surface of a molten metal bath (162) contained in a float tank (160). The width Wm of the multi-layer glass melt (300) is less than the width Wf of the float tank (160) prior to the multi-layer glass melt (300) entering the float tank (160). The multilayer glass melt (300) flows over the surface of the molten metal bath (162) such that the width Wm of the multi-layer glass melt (300) increases, the melt thickness Tm decreases, and the core to cladding thickness ratio TC:TCl remains constant as the multi-layer glass melt (300) solidifies into a laminated glass sheet. The invention also relates to the associated apparatus.
