The Carrier100it has been formed with a number of sets of molds110, sized to accept glass film with a thin surface compression pattern. the mold is set up110are formed in sequential order at a distance such that one set of molds is adjacent to at least two other sets of molds. The Carrier100configured with a conveyor roller assembly140, which includes a conveyor pressure roller144.
Once the finely pressed glass ribbon patterned surface is routed out of the delivery and processing system50, the finely compressed glass ribbon is deposited along a plurality of transfer molds110. The transfer molds are placed in a substantially horizontal direction so that gravity assists the finely compressed glass strip placed over the mold assemblies.110. In addition, the delivery time of compressed thin glass from the delivery and processing systems50in the transfer moulds110along the conveyor108can be synchronized so that the fine clamping area is outside the working surface of the die sets110(for example, outside the mold width or between mold assemblies in a row). Conveyor roller assembly140It is configured with a conveyor pressure roller144which has a constant surface, where the surface of the cylinder144it is formed with a number of raised projections on its surface. Conveyor pressure roller144acts on an upper surface of the deposited glass film, pressing the deposited glass film into a flattened configuration against the mold assembly110and the corresponding mold surface120, while pressing the surface/set of projections of the conveyor arm pinch roller144on the first surface of the tape material. The tape material is thus cast by engagement between the die surface and the conveyor pressure roller surface to define a plurality of portions of molten tape material on the lower surface of the tape material.
As the cast glass film sections continue to travel along the conveyor108, the glass continues to cool. The reduced temperature is sufficient to cause a break in the glass along the thin grip line so that the molded glass strip separates into a plurality of surface-patterned molded glass components as the conveyor directs the molded glass components.100. Optionally, a component removal unit160is set for carrier output108so that a positive pressure actuator162blows air from the conveyor to facilitate lifting of the plurality of surface-patterned molded glass pieces from the conveyor and/or separating two or more surface-patterned molded glass pieces from each other along the thin clamping line(s).
The thin film deposition device200Includes a pair of shaping rollers212, including a first forming roll and a second forming roll. the forming rollers212are configured to direct a continuously supplied batch of molten material (eg glass, ceramic and/or glass ceramic) onto a ribbon. The tape is configured with two main surfaces, a first and a second surface, and two corresponding edges, a first edge and a second edge.
The film is then passed through a pair of sizing rollers.218, including a first sizing roller and a second sizing roller. The sizing roller is configured to operate on the surfaces of the glass strip (first major surface, second major surface, and first and second edges) to form the glass to a uniform thickness (eg, as measured across its length and width). . Following the sizing rollers, the uniform glass ribbon is directed to a pair of fine pressure rollers.224, here the fine nip rolls are configured with at least one textured cut roll, including a first and second fine nip rolls.
After the collar rolls, the uniform tape material is directed to a pair of pin rolls (a first pin roll and a second pin roll), where at least one surface of the pin rolls is formed with a plurality of pin roll raised bumps. In some embodiments, both the first pin cylinder and the second pin cylinder are formed with a plurality of raised projections on their respective surfaces. As the uniform tape material travels through the pair of pin rolls, the extending protrusions act on at least one (or both) of the first and second tape material surfaces to impart notches to the cross-sectional thickness of the tape. .
The thin pressure rollers are configured to convey a plurality of grip areas on at least one of: the first major surface and the second major surface, with sufficient engagement of the glass strip between the pair of thin pressure rollers to grip, but not separately. the glass film.

The glass delivery system60provides molten material (eg glass, ceramic or glass-ceramic material) to the glass processing system70. The glass processing system70includes: forming rollers;212(first forming roll and second forming roll). sizing rollers218(first sizing roller and second sizing roller) and pressure rollers224(first pressure roller and second pressure roller).
the forming rollers212are configured to form a hot, flexible strip material (eg, glass tape material, ceramic tape material, or glass ceramic tape material) from the supplied molten material. Once formed, the strip material is formed to the proper width and thickness (ie, uniform thickness) by sizing rolls.218.
Once the tape is formed and sized, the pressure rollers224are shaped to provide a pinch on the tape material, thereby creating a pinch area on the tape material. The grip area is configured to define the boundary between: the component and the glass shell, between distinct parts and/or combinations thereof. The pinch region, along with the original cross-sectional thickness glass ribbon, is configured to be processed downstream as a single piece (eg ribbon material + pinch region), which is continuously removed from the glass supply60for tape placement system200, including: roll forming212, sizing rolls218and fine pinch224rolls.

Conveyor roller assembly140is configured with at least one roll. At least one cylinder can be configured as: pressure cylinder146(with matching handle ends)148), a pressure cylinder144, a pressure roller (for example, with a smooth surface), a pressure roller with a three-dimensional surface pattern150(eg micro pattern or macro pattern) and/or combinations thereof.
Conveyor roller assembly140has been framed142which includes a motor, the cylinder138, and accompanying optional hydraulics (eg, configured to provide engagement between the roll and the tape material). The Carrier100is configured with a wheeled frame assembly configured to be adjustable relative to the position of the glass processing system40. The controller roller assembly140the roller is engaged with a first surface of the strip material such that the compressed strip material is engaged between the surface of the die120and the roll138. Depending on the configuration of the pressure arm cylinder138and/or mold surface120(or mold case114), the compressed tape material is further processed as it travels along the conveyor.
While the film is passing through the film processing system40and transportation system100, the film slowly cools down. Once sufficiently cooled, the compressive stresses generated between the pinch area and adjacent sections (eg, with a cross-sectional thickness corresponding to most of the strip material) are high enough to cause the strip material to separate along the bite area. The resulting separation along the pinch region creates distinct parts and/or hulls depending on the configuration of the pinch regions and the shape/dimension of the resulting product.
After discrete pieces of the finely compressed glass strip are formed, the pieces can be vacuum lifted from the conveyor or removed from the mold(s) as the mold reaches the end of the transport section (eg, while the molds are still horizontal , before being raised/placed in a vertical position). Parts can be further processed. For example, the edges of the section defined by the pinch area separation can be fire polished to smooth the edges. Alternative processing includes: machining, acid etching, laser processing and/or combinations thereof.
In addition, the conveyor supports are also vertically adjustable - also allowing the distance between the ribbon drop system to be adjusted200and the transport system100.
