Abstract: Systems and methods for remediating streak in glass ribbons formed from glass forming processes are disclosed. The systems include a laser that produces a stationary laser beam having a wavelength of from about 1 ?m to about 12 ?m and a beam width less than or equal to a full width half maximum of a change in the thickness of the glass ribbon over a streak width at a streak location and optical components to condition and direct the laser beam at the streak location. The methods include forming the glass ribbon, identifying a streak in the glass ribbon, and directing the laser beam at the streak location. The laser beam heats the glass ribbon at the location of the streak, which reduces a viscosity of the glass ribbon to cause glass thinning that reduces the severity of the streak.

Abstract: Glass manufacturing apparatus comprise a forming body configured to draw a glass forming ribbon and positioned within an enclosure. Glass manufacturing apparatus comprise a first diffuser comprising a first inlet comprising a first inlet cross-sectional area and a first outlet comprising a first outlet cross-sectional area. The first outlet cross-sectional area is greater than the first inlet cross-sectional area. The first outlet is positioned within the enclosure. Methods of manufacturing a glass ribbon comprise flowing a glass-forming ribbon. Methods comprise flowing a first gas through the first inlet of a first diffuser at a first average inlet velocity. Methods comprise flowing the first gas from the first diffuser through a first outlet of the first diffuser at a first average outlet velocity. The first average inlet velocity is greater than the first average outer velocity.
