摘要:
A method and apparatus for processing glass comprising a forming apparatus in a first processing zone, the forming apparatus configured to form a glass ribbon having a first direction of travel in the first processing zone. The apparatus also includes a first cutting apparatus in a second processing zone, the first cutting apparatus configured to separate one or more portions of the glass ribbon, the glass ribbon having a second direction of travel. The apparatus includes a first buffer zone between the first processing zone and the second processing zone in which the glass ribbon is supported in a first catenary between two, spaced-apart payoff positions. The second direction of travel in the second processing zone can be orthogonal to the first direction of travel in the first processing zone.

A steering apparatus comprises a steering member for fluid steering of a glass web. The steering member comprises a recessed channel defining a primary flow path extending in a primary flow direction toward a downstream end of the steering member. A fluid port is configured to introduce fluid into the recessed channel to at least partially flow in the primary flow direction along the primary flow path and out an open end of the recessed channel. In further examples, methods of conveying a glass web with the steering apparatus include conveying the glass web along a conveyance path and guiding a primary steering steam of fluid with the recessed channel along the primary flow path in the primary flow direction and out the open end of the recessed channel to steer the glass web in a direction transverse to the conveyance path.
摘要:
A tiled display having pixels arranged in rows and columns, and including first and second tiles. The tiles comprise a substrate carrying a matrix of pixels arranged at a pixel pitch. The substrates comprise an edge extending between opposing faces in a depth direction. The substrate edges have a complementary shape, and face one another to establish a seam. The pixel pitch is maintained across the seam. Pixels of the second tile are not interposed between pixels of the first tile. The complementary shape includes a segment of the seam being oblique to the pixel rows, or the substrate edge of the first tile profiled in the depth direction whereby at least a section of the edge is non-perpendicular to the faces. The tiled display can maintain the pixel pitch at the seams at high resolutions (e.g., pixel pitch less than 0.5 mm).

A method of continuous processing of flexible glass ribbon having a thickness of no more than 0.35 mm using a glass processing apparatus is provided. The method includes providing the glass processing apparatus having at least three processing zones including a first processing zone, a second processing zone and a third processing zone. The flexible glass ribbon is continuously fed from the first processing zone, through the second processing zone to the third processing zone. Rate of the flexible glass ribbon is controlled through each of the first processing zone, second processing zone and third processing zone using a global control device. The second processing zone has a conveyance path for the flexible glass ribbon through a cutting zone having a radius of curvature of from about 100 inches to about 400 inches.

A method of continuously processing glass ribbon having a thickness ≤ 0.3 mm. The method includes providing a glass processing apparatus having a first processing zone, a second processing zone and a third processing zone. The glass ribbon is continuously fed from the first processing zone, through the second processing zone to the third processing zone. The feed rate of the glass ribbon is controlled through each processing zone using a global control device. A first buffer zone is provided between the first processing zone and the second processing zone in which the glass substrate is supported in a first catenary between two, spaced-apart, payoff positions. A second buffer zone is provided between the second processing zone and the third processing zone in which the glass substrate is supported in a second catenary between two, spaced-apart, payoff positions.
摘要:
A process and apparatus is disclosed for finishing long strips of thin glass web material. The process and apparatus provide for the movement of the thin glass web material in a downward vertical direction and preforming various finishing process for example slitting, taping, and testing before the thin glass web material is wound on to a roll. The process and apparatus operate such that the thin glass web material is not contacted by the apparatus and is thus protected from potential damage.

A system, process and related sintered article are provided. The process includes supporting a piece of inorganic material with a pressurized gas and sintering the piece of inorganic material while supported by the pressurized gas by heating the piece of inorganic material to a temperature at or above a sintering temperature of the inorganic material such that the inorganic material is at least partially sintered forming the sintered article. The inorganic material is not in contact with a solid support during sintering. The sintered article, such as a ceramic article, is thin, has high surface quality, and/or has large surface areas.

Methods and apparatus provide for: conveying a glass web from a source toward a destination in a transport direction; scoring the glass web in a width direction thereof to produce a score line having a plurality of separated score segments, thereby defining a section of the glass web between the score line and a leading edge of the glass web; supporting the glass web such that an increasing portion of the section of the glass web becomes cantilevered as the glass web is conveyed such that the portion of the section of the glass web is sufficiently large to generate stress in the respective score segments and drive respective cracks through the thickness of the glass web; and permitting the section of the glass web to separate from the glass web along the score line.

In one embodiment, an angle measurement device for measuring an angle between a web of material and a conveyance direction includes a mounting bracket, a shaft rotatably coupled to the mounting bracket such that the shaft is rotatable with respect to the mounting bracket, a caster portion coupled to a first end of the shaft and positioned to contact a surface of the web of material being drawn over a web conveyance pathway, where the caster portion is spaced apart from an axis of rotation of the shaft, and an angular displacement sensor coupled to the mounting bracket and positioned to detect an angular orientation of the shaft with respect to the mounting bracket, where the angular displacement sensor outputs a signal indicative of the angular orientation of the shaft with respect to the mounting bracket.
摘要:
Methods apply a layer of material to a glass sheet having a non-planar shape. The methods can each include the step of providing the glass sheet having an initial non-planar shape including a thickness defined between a first sheet surface and a second sheet surface. The method further includes the step of at least partially flattening the glass sheet into an application shape. The method further includes the step of applying the layer of material to the first sheet surface while the glass sheet is in the application shape. The method then includes the step of releasing the glass sheet to relax into a post non-planar shape.
