摘要： A glass manufacturing apparatus includes a forming apparatus defining a travel path extending in a travel direction. The forming apparatus conveys a ribbon of glass-forming material along the travel path in the travel direction. The glass manufacturing apparatus includes a cooling tube including a first end and a second end. The cooling tube includes a first tube including a closed first sidewall surrounding a first channel. The first tube receives a first cooling fluid within the first channel. The cooling tube includes a second tube including a closed second sidewall surrounding a second channel. The first tube is positioned within the second tube. The second tube receives a second cooling fluid within the second channel. The cooling tube includes a nozzle. The nozzle receives the first cooling fluid and directs the first cooling fluid toward the travel path. Methods include manufacturing a glass ribbon with the glass manufacturing apparatus.

摘要： A laminate includes a first glass article having a first thickness, a first annealing point (TA1), and a first softening point (TS1), a second glass article having a second thickness, a second annealing point (TA2), and a second softening point (TS2), and an interlayer disposed between the first glass article and the second glass article. The first thickness is greater than the second thickness, the second annealing point (TA2) is less than or equal to the first annealing point (TA1), and the second softening point (TS2) is greater than the first softening point (TS1).

摘要： 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.

摘要： A system and process for forming a curved glass laminate article is provided. The process and system utilizes co-sagging of a stack of glass sheets of different thicknesses and different glass materials. During co-sagging the thicker glass layer is placed on top of the thinner glass layer. In this process, shape mismatch is avoided by selecting/controlling the glass materials of the sheets of glass such that the viscosity of the lower, thinner sheet during co-sagging is greater than the viscosity of the thicker glass sheet.

摘要： A system and process for forming a curved glass laminate article is provided. The process and system utilizes a separation material, such as solid lubricating material and/or a spray applied separation material that Applicant has determined reduces bending dot formation during co-sagging shaping of glass sheets. The bending dot reduction provided by the separation materials discussed herein is particularly seen when the pair of glass sheets have significantly different thicknesses and/or viscosities from each other.

摘要： A glass manufacturing apparatus includes a forming apparatus defining a travel path extending in a travel direction. The forming apparatus conveys a ribbon of glass-forming material along the travel path in the travel direction of the forming apparatus. The glass manufacturing apparatus includes a cooling tube extending substantially parallel to the travel path and extending across the travel direction. The cooling tube includes a plurality of orifices spaced apart along the cooling tube and facing the travel path. Methods of manufacturing glass can comprise flowing a coolant from an outlet of a conduit in a direction toward a target location of a flowing ribbon of molten material. Methods can also include changing a phase of the coolant while the coolant is flowing towards the target location. The change in phase can cool the target location.
