A control apparatus for controlling a thickness of a substrate, such as a glass ribbon. The control apparatus comprises a laser assembly and a shielding assembly. The laser assembly generates an elongated laser beam traveling in a propagation direction along an optical path. The shielding assembly comprises at least one shield selectively disposed in the optical path. The shield is configured to decrease an optical intensity of a region of the elongated laser beam. The shielding assembly is configured to change an intensity profile of the elongated laser beam from an initial intensity profile to a targeted intensity profile. A desired targeted intensity profile can be dictated by an arrangement of the shield(s) relative to the optical path, and can be selected to affect a temperature change at portions of the substrate determined to benefit from a reduction in thickness.

Apparatus and method for controlling substrate thickness

Apparatuses for making a laminated glass ribbon may include an upper forming body including an outer forming surface bounded by a pair of upper dams, and a lower forming body disposed downstream of the upper forming body and including an outer forming surface spaced from the outer forming surface of the upper forming body by an interior gap. An edge guide may be disposed along an interior upper dam wall and spaced apart in the interior gap from the lower forming body. Surfaces exterior to the outer forming surfaces of the upper and lower forming bodies may abut and be joined. A formed glass ribbon having a core glass layer and a pair of clad glass layers may include inner and outer portions that have substantially equal thickness ratios based on a glass core layer thickness compared to a combined glass cladding layer thickness in each portion.

Laminated glass ribbons and apparatuses for forming laminated glass ribbons

A glass article including any one or several of SiO, AlO, BO, LiO, SnOand a fusion line. The glass article can also include a liquidus viscosity less than or equal to 100 kP. In some embodiments, the glass article includes, on an oxide basis, from 60 mol % to 74 mol % SiO, from 7 mol % to 18 mol % AlO, from 3 mol % to 16 mol % BO, from 0 mol % to 6 mol % NaO, from 0 mol % to 5 mol % PO, from 5 mol % to 11 mol % LiO, less than or equal to 0.2 mol % SnO.

Low viscosity glasses and methods and systems for manufacture

An apparatus for making a glass sheet including a forming apparatus, a transition member, and a heat transfer device. The forming apparatus forms a glass ribbon from a supply of molten glass. The transition member encloses the glass ribbon adjacent the forming apparatus, and defines an interior space through which the glass ribbon passes. The heat transfer device is disposed within the interior space, and comprises a tube and a fin. The tube defines an exterior surface and an interior passage. The fin projects from the exterior surface. With this construction, the heat transfer device functions to extract heat radiated by the glass ribbon while minimizing the formation of flow vortices.

Apparatus and method for rapid cooling of a glass ribbon in a glass making process

Disclosed is a method of separating a glass sheet from a moving glass ribbon, wherein the glass ribbon comprises thickened bead portions. The method comprises weakening the bead portions of the ribbon using laser-initiated ablation at the bead portions to overcome the potential for uncontrolled cracking through the bead portion.

Method for low energy separation of a glass ribbon

Disclosed are methods for compensating the varying weight of a glass ribbon the glass ribbon is drawn from a molten glass forming material, and an apparatus therefore. The weight compensating apparatus is configured to apply a force to the glass ribbon that is inversely proportional to the weight of the glass ribbon such that as the glass ribbon weight increases, the force applied to the glass ribbon by the weight compensating device decreases.
