A base material for a disk roll containing a layered silicate, in which the layered silicate is constituted to contain two or more kinds of minerals having an interlayer distance exceeding 10 angstroms. A base material for a disk roll is excellent in the compressive strength and wear resistance thereby.

A method of manufacturing a glass film includes a forming step of forming a band-shaped glass film by pulling down a glass ribbon flowing down from a forming trough while sandwiching the glass ribbon from both front and back sides through use of roller pairs and a conveyance direction changing step of changing a conveyance direction of the glass film from the vertical direction to the horizontal direction by conveying the glass film along a conveyance path having an arc shape while supporting the glass film from a back surface side with a roller conveyor so that a front surface of the glass film after having passed through the conveyance path faces upward. A first roller to be brought into abutment against the glass film from the front surface side is arranged between a roller pair arranged in a lowermost stage and the roller conveyor.

A glass manufacturing apparatus comprises a forming device configured to produce a glass ribbon and a control device configured to independently operate a first pull roll apparatus and a second pull roll apparatus such that the first pull roll apparatus rotates with a substantially constant torque the second pull roll apparatus rotates with a substantially constant angular velocity. The control device is further configured to adjust the substantially constant torque of the first pull roll apparatus based on an operating condition of at least one of the first pull roll apparatus and the second pull roll apparatus. In further examples, methods of manufacturing a glass ribbon are provided.

An apparatus for making a glass laminate, including: a source of a glass core sheet; a source of a first force that tensions the glass core sheet in a first axial direction; a source of a second force that tensions the glass core sheet in a second axial direction; and at least one molten glass reservoir extending along a length of the apparatus and on opposite sides of the glass core sheet that delivers a source of at least two glass clads to the opposite side surfaces of the bi-axially tensioned glass core sheet. Also disclosed are methods for making a glass laminate sheet using the disclosed apparatus, as defined herein.

Disclosed is an apparatus and method of making molten glass. The apparatus includes a glass former having a slot orifice design to deliver a glass ribbon. The slot orifice design can include a transition section, a slot extension, and external structural reinforcements. In some embodiments, the orifice opening distance of the slot extension varies along the width of the orifice. In some embodiments, the orifice has an orifice opening distance that is smaller at the center of the slot extension than at the edges of the slot extension, which limits glass flow at the center of the slot extension. Also disclosed is a method of making glass using the disclosed apparatus.

A glass manufacturing system and method are described herein for forming a high quality thin glass sheet. In one embodiment, the glass manufacturing system and method use at least one of a compensated rolling roll, a temperature controlled environment and edge rolls to form a high quality thin glass sheet that has a thickness less than about 2 mm and more preferably less than about 100 m.

A cartridge assembly includes a hub portion having a first end and a second end, a first retaining ring portion including a first snap ring and a first retaining ring member, and a second retaining ring portion including a second snap ring and a second retaining ring member. The cartridge assembly further includes a plurality of disc elements positioned between the first retaining ring portion and the second retaining ring portion, where the plurality of disc elements has an outer diameter that is greater than an outer diameter of the first retaining ring portion and the second retaining ring portion, and a plurality of fastening members positioned at the first end and the second end of the hub portion, the plurality of fastening members extending radially inward from the hub portion.

Disclosed herein are methods for continuous processing of a thin, flexible glass ribbon through various processing zones and maintaining a concave or substantially linear machine directional (MD) and/or cross-directional (CD) curvature of the flexible glass ribbon through at least two or more contiguous zones in the process. Apparatuses for the continuous processing of a thin, flexible glass ribbon while maintaining a desired MD and/or CD curvature are also disclosed herein.

Provided is a manufacturing apparatus (1) for a glass sheet, including roller pairs (5), which are configured to convey a glass ribbon (G) downward while sandwiching the glass ribbon (G) from both front and back sides, and are arranged in a plurality of vertical stages, wherein each of rollers forming each of the roller pairs (5) is formed so as to be movable between a sandwiching position for sandwiching the glass ribbon (G) a retracted position that is separated from a conveyance path (P) of the glass ribbon (G) and is capable of preventing contact of flying objects flying from above, and wherein, when the glass ribbon (G) during conveyance is damaged, the roller (5a) that is positioned below a damaged part of the glass ribbon (G) moves to the retracted position.

Glass manufacturing apparatuses with cooling devices and methods for using the same are disclosed. In one embodiment, an apparatus for forming a glass web from molten glass includes an enclosure and pulling rolls that cooperate to draw a glass web in a draw direction rotatably positioned in an interior of the enclosure. A cooling device for extracting heat from the glass web is in fluid communication with a cooling fluid source and includes an actively cooled flapper disposed in the interior of the enclosure that is movable to facilitate varying the heat extraction. The actively cooled flapper serves as a heat sink in the interior of the enclosure and the cooling fluid extracts heat from the actively cooled flapper to remove heat from the glass web and the enclosure.
