An apparatus and method for positioning and receiving the shaft of a glass forming roll includes a rotatable member and a radially moveable member mounted on the rotatable member, the radially moveable member having a bore for receiving the shaft of the glass forming roll and movable between a first position and a second position, the first position closer to an axis of rotation of the rotatable member than the second position

Various aspects of methods and systems are provided, which detail: a method, comprising: depositing a hot, flexible glass-containing ribbon along a plurality of sequentially conveyed molds; rolling a pinch roller over the surface of the glass-containing ribbon, such that at least one pinch region is actuated in the glass ribbon as the glass ribbon is pinched between a pinch edge of the pinch roller and the surface of the mold; and cooling the glass ribbon, separating the glass ribbon along the pinch region into discrete glass parts.

A method of manufacturing glass ribbon can comprise feeding molten material through a minimum width of a first gap defined between a first roller and a second roller of a first pair of rollers. A first pool of molten material can be formed upstream from the minimum width of the first gap. A ribbon of molten material can exit the first gap. The methods can further include passing the ribbon of molten material through a minimum width of a second gap defined between a first roller and a second roller of a second pair of rollers. The minimum width of the first gap can be greater than the minimum width of the second gap. A second pool of molten material can be formed upstream from the minimum width of the second gap.

A glass sheet (1) having a rectangular shape includes a first side (1y) along a sheet-drawing direction (Y) and a second side (1x) along a width direction (X), and has a length of each of the first side (1y) and the second side (1x) of 1,000 mm or more, and a sheet thickness of 0.1 mm or more and 2.0 mm or less. When five evaluation regions (A) to (E) having rectangular shapes of the same size are sequentially set from one end side in the width direction (X), the absolute value of the average of the front-back deflection differences (X1X2) of the evaluation regions (A) to (E) in the width direction (X) is 0.06 mm or more and 0.8 mm or less.
