A tool for local cooling by contact of a glass sheet at a temperature higher than 450° C., known as a contact tool, includes a contact face suitable for coming into contact with the glass sheet, the tool including an internal pipe for the circulation of a coolant, in particular air. The tool is used in a device for bending and/or cooling a glass sheet, in particular individual, the tool coming into contact with the glass sheet while it is held by a bending tool or by a cooling frame after bending. A compression zone is created that is capable of being drilled to form an edge having compressive stresses.

According to an aspect of the disclosure, a glass manufacturing system includes a hot-end subsystem, including: a submerged combustion melter that melts feedstock to produce molten glass; a stiller that receives the molten glass from the submerged combustion melter and that includes a stilling tank to still the molten glass and that is configured to control outflow of the stilled molten glass to effectively decouple viscosity of the molten glass from the flow rate of the molten glass and thereby control finer molten glass levels; and a finer that is mechanically decoupled from the stiller, and that receives and fines the stilled molten glass to produce fined molten glass. Many other aspects of the system are also disclosed and claimed.

A glass tube element having hollow cylindrical section that has a shell enclosing a lumen and extends along a main extension and an optical delay of a light ray. The shell has a surface facing away from the lumen. The optical delay has values that all fall within a range having a size of between 3 and 30 nm. The optical delay being an optical measurement of the glass tube element by the light ray extending along a measurement path in a direction of perpendicular to the main extension and tangent to a surface of the shell. The measurement path touches the surface for different measurements at different positions each having a different azimuth angle within a cylindrical coordinate system fixedly attached to the glass tube element and having an origin on a center axis of the glass tube element.

The present invention relates to a method for manufacturing glass containers for pharmaceutical use. This method allows obtaining containers with a low degree of alkalinity. In some preferred embodiments the process allows the manufacture of sterile containers and substantially free of particles ready to be used by the pharmaceutical industry.

A glass production apparatus producing continuously curved glass for covers and containers includes a crucible, a calender device, a cutting device, a molding device, and a crystallizing device. The crucible melts glass raw material and outputs a glass melt to calender device. The calender device rolls and presses the glass melt to prepare a glass belt with a preset temperature. The cutting device cuts the glass belt with the preset temperature into glass members. The molding device include at least one molding mold and a manipulator. Each of the at least one molding mold curves at least one portion of the glass member with the preset temperature to prepare a curved glass member. The manipulator transfers the curved glass member to the crystallizing device, the crystallizing device crystallizes the curved glass member to prepare a curved crystalline glass member. A method for manufacturing such glass is also provided.

Method for manufacturing a flush vehicle glazing that allows to achieve a perfect alignment between the adjacent sections of the glazing vehicle area in the final assembled product by providing a vehicle glass panel which comprise at least two adjacent sections of the vehicle glazing area in one single panel, followed by bending the vehicle glass panel and LASER cutting before cooling thereof.

A method for producing a hollow glass product by an I.S. machine, said method being a press-blow or blow-blow method and implementing at least one parison mould and one blow mould, said method comprising the lubrication of said parison mould, the lubrication comprising spraying via a nozzle, said nozzle being carried by the arm of a mobile robot movable along the parison mould side of the I.S. machine, characterised in that said mobile robot is configured to bring said nozzle into the lubricating position after the glass gob has left the parison mould for the blow mould; spray the lubricant into said parison mould; withdraw said nozzle from the lubricating position before the transfer arm returns between the two half-moulds of the parison mould.
