Abstract: A glass ribbon (10) including a first glass-ribbon portion (12) and a second portion (22) separated from one another by a gap (40), and a splice joint (30) coupling the first glass-ribbon portion to the second portion. The splice joint includes a splice member (31) having a Young's modulus and cross sectional area so that when subject to a force of 20kg the splice member undergoes an elongation of ≤ 20%. A filler material (80) may be disposed in the gap. Also, there are disclosed methods of splicing a glass ribbon, and preparing a coated glass ribbon for splicing. One embodiment of a method of splicing glass ribbon includes applying tape (70) to the glass ribbon, and cutting the glass ribbon together with the tape so as to create a free end in the glass ribbon. Before the glass ribbon is cut, a fracture line (75, 77) may be created in the glass ribbon wherein the tape is disposed across the fracture line. When preparing a coated glass ribbon, a separate tape member need not be applied before creating the fracture line or cutting the glass ribbon.

Abstract: Non-contact, liquid-ejecting bearings (3) are provided for conveying flexible glass sheets (13), such as LCD substrates, at high conveyance speeds, e.g., speeds of 15 meters/minute and above. The operating parameters and physical properties of the bearings satisfy at least one of the following conditions: (a) the average flow rate from the bearing's orifices (22) is in the range of 100-800 milliliters/minute/orifice; (b) the orifices' average horizontal pitch (P) is in the range of 20-55 millimeters; and/or (c) the orifices' average size (e.g., D0) is in the range of 1.0-4.5 millimeters. The bearings (3) can reduce the time-averaged, peak-to-peak variation in the spacing between a LCD substrate (13) traveling at 15 meters/minute and the face (20) of the bearing (3) to less than 100 microns, thus reducing the chances that the bearing (3) will lose control of the substrate (13) or that the substrate (13) will hit the bearing (3).

Abstract: Disclosed are systems and methods for forming glass sheets. Methods and systems are provided that comprise a refractory body configured to receive glass-based material and means for transmitting energy to selectively heat at least a portion of the refractory body through the glass-based material. In one aspect, the energy transmitted is of a selected frequency that is not fully absorbed by the glass-based material and is at least partially absorbed by the refractory body. The energy can be transmitted by a laser beam array, a scanning laser beam, a microwave generator, a radio frequency generator, or other means.

Abstract: Foldable substrates comprise a substrate thickness from about 80 micrometers to about 2 millimeters. Foldable substrates comprise a first portion, a second portion, and a central portion positioned therebetween. The central portion comprises a central thickness from about 25 micrometers to about 80 micrometers defined between a first central surface area and a second central surface area. A central total thickness variation of the central portion over the first central surface area is less than or equal to 10 micrometers. The central portion comprises a first transition region extending between a first surface area of the first portion and the first central surface area. The first central surface area is recessed from the first major surface by a first distance. A thickness of the first transition region smoothly and monotonically decreases between the substrate thickness of the first portion and the central thickness of the central portion.
