A method of forming a shaped glass article includes placing a glass sheet on a mold such that a first glass area of the glass sheet corresponds to a first mold surface area of the mold and a second glass area of the glass sheet corresponds to a second mold surface area of the mold. The first glass area and the second glass area are heated such that the viscosity of the second glass area is 8 poise or more lower than the viscosity of the first glass area. A force is applied to the glass sheet to conform the glass sheet to the mold surface. During the heating of the second glass area, the first mold surface area is locally cooled to induce a thermal gradient on the mold.

The present invention discloses a device for processing columnar curved tempered glass. The device mainly comprises a glass heating furnace, a glass bending mechanism and a glass tempering mechanism connected sequentially, wherein the arrangement of each supporting roller in the rollers supporting the high temperature flat glass is changed from planar arrangement in space into curved arrangement corresponding to the shape of the glass to be formed, so that the glass bending mechanism enables the glass to suffer bending deformation. Transferring rollers for outputting the formed curved glass in the axial direction of the supporting roller are arranged at the clearance of the rollers of the bending mechanism. In the present invention, bending shaping and tempering of the high temperature flat glass are completed by two stations to break the normal procedure that bending shaping tempering are carried out by one bending appliance intensively, thereby providing a novel technological approach for processing columnar curved tempered glass.

The invention relates to a method for shaping a glass sheet having a reflective low emissivity coating thereon comprising the steps: (i) positioning the coated glass sheet at a furnace entrance; (ii) conveying the coated glass sheet through the furnace to heat the glass sheet to a temperature suitable for shaping; (iii) transferring the coated glass sheet on to a first bending tool for supporting the coated glass sheet, the first bending tool having a fixed wall and first, second and third movable walls; (iv) moving at least one of the first, second and third movable walls to adjust the position of the coated glass sheet on the first bending tool ring from a first position to a second position; and (v) shaping the coated glass sheet between the first bending tool and a die. Apparatus for carrying out the method is also disclosed.

A glass sheet press forming station (32) and method for press forming hot glass sheets with transverse curvature is performed by initially limiting the central forming of a glass sheet (G) between its end portions upon pickup from a roll conveyor to an upper mold (38) and prior to press forming with an associated lower mold (66) to prevent central area optical distortion of the press formed glass sheet.

A method of forming a shaped glass article includes placing a glass sheet on a mold such that a first glass area of the glass sheet corresponds to a first mold surface area of the mold and a second glass area of the glass sheet corresponds to a second mold surface area of the mold. The first glass area and the second glass area are heated such that the viscosity of the second glass area is 8 poise or more lower than the viscosity of the first glass area. A force is applied to the glass sheet to conform the glass sheet to the mold surface. During the heating of the second glass area, the first mold surface area is locally cooled to induce a thermal gradient on the mold.

Provided is a method of manufacturing a glass roll (GR), including: a conveying step of conveying a band-shaped glass film (G2) in a lateral conveying direction by a conveying device (4); and a roll-up step of rolling up the glass film (G2) into a roll shape. The conveying step includes an inspection step of measuring a state of each of end portions (Gd, Ge) in a width direction of the glass film (G2) by a detection unit (19a, 19b) under a state in which a tension is applied to the glass film (G2) that passes through an intermediate conveying region (MS) of the conveying device (4) by a tension applying portion.

A glass slumping fixture comprises a structure including a first side surface, a spaced-apart second side surface, and a top surface positioned therebetween and connected to each side surface. The structure further includes spaced apart slots that are positioned on the first side surface, the second side surface, and the top surface, each slot being an indentation that extends along at least a portion of a height of the first side surface, at least a portion of a height of the second side surface, and across the top surface from the first side surface to the second side surface. The structure retains a glass sheet during a slumping process including the glass sheet being placed on the top surface over the slots and heated until a first portion of the glass sheet contacts the first side surface and a second portion of the glass sheet contacts the second side surface.

Apparatus for shaping a coated glass sheet comprising a roller conveyor for conveying a coated glass sheet, a die and frame having a rim for supporting the coated glass sheet thereon in the shape of a target product, the frame having a fixed wall and at least one movable wall.

A method of shaping a glass sheet includes providing a glass sheet. Also, a bending station is provided. The bending station includes a first bending tool. The first bending tool has a shaping surface for receiving the glass sheet. The glass sheet is conveyed on a plurality of rollers to a location above the first bending tool. At least a portion of the glass sheet is supported above the first bending tool by delivering a flow of fluid to a major surface of the glass sheet. The glass sheet is deposited on the shaping surface of the first bending tool.
