Abstract:
Various embodiments of methods and related equipment are provided, comprising: delivering a molten material into a forming and sizing assembly, processing the molten glass via the at least one pair of forming and sizing rollers to form a glass ribbon having a width and a thickness; imparting, at least one pinch region into the cross-sectional thickness of the glass ribbon to provide a pinched glass ribbon, rolling a pressure roller over the pinched glass ribbon on the sequentially spaced mold surfaces to impart a characteristic into the pinched glass ribbon to form a glass ribbon product.
Abstract:
A glass manufacturing apparatus includes a delivery apparatus defining a travel path extending in a first travel direction. The delivery apparatus conveys a stream of molten glass along the travel path. The glass manufacturing apparatus includes a first forming roll and a second forming roll spaced to define a gap that provides a glass ribbon with a width and a thickness. One or more of the first forming roll or the second forming roll include a textured feature that imparts a corresponding textured feature to the glass ribbon. The glass manufacturing apparatus includes a mold defining a mold cavity. The mold is positioned to receive a portion of the glass ribbon to impart a shape to the portion. The glass manufacturing apparatus includes a conveyor that moves the mold in a second travel direction angled relative to the first travel direction. Methods of manufacturing a glass ribbon are provided.
Abstract:
According to one or more embodiments described herein, a three-dimensional laminate glass article may be manufactured by a process which may include heating a glass stack including at least two glass sheets that are unbonded with one another at a first temperature range, fusing the first glass sheet with the second glass sheet by heating the glass stack at a second temperature range, and shaping the glass stack. The first temperature range may be from about 150° C. to about 400° C. for a first period of time of at least about 5 minutes. The second temperature range may be from about 400° C. to about 1200° C.
Abstract:
Provided herein is a method for producing glass-ceramic sheets. The method includes texturing at least one surface of a first glass sheet, and stacking the first glass sheet and a second glass sheet. The first glass sheet and the second glass sheet are stacked so that the textured surface of the first glass sheet contacts a surface of the second glass sheet. The first and second glass sheets are cerammed. After cooling, the cerammed first and second glass sheets are separated. Also provided is a pre-form for producing glass-ceramic sheets. The pre-form includes a first glass sheet having a textured surface, and a second glass sheet contacting the first glass sheet. The textured surface of the first glass sheet is in contact with a surface of the second glass sheet.
Abstract:
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.
Abstract:
A method of forming a glass sheet comprises: (a) forming a ribbon of glass from molten glass with a pair of forming rollers; (b) reducing horizontal temperature variability of the ribbon of glass to be 10° C. or less across 80 percent of an entire width of the ribbon of glass before the ribbon of glass cools to a glass transition temperature; (c) controlling a cooling rate of the ribbon of glass while the ribbon of glass moves vertically downward within a setting zone such that the ribbon of glass has a first average cooling rate before the ribbon of glass cools to the glass transition temperature and a second average cooling rate after the ribbon of glass cools to the glass transition temperature, the first average cooling rate being less than the second average cooling rate; and (d) separating a glass sheet from the ribbon of glass.
