A device for picking up, shaping, and placing a thin glass pane, includes a frame with an upper side and a lower side, which is suitable to be directed at a glass pane with a thickness of less than 1 mm, and which is provided with a plurality of picking up pins that are arranged substantially parallel to one another and whose end directed at the glass pane is equipped with a suction cup, wherein the picking up pins are movable along their direction of extension independent of one another in order to adapt the arrangement of the suction cups to an intended shape of the glass pane.

A method for homogenizing glass includes the method: providing a cylindrical blank composed of the glass having a cylindrical outer surface that extends along a longitudinal axis of the blank between a first end face and a second end face, forming a shear zone in the blank by softening a longitudinal section of the blank and subjecting it to a thermal-mechanical intermixing treatment, and displacing the shear zone along the longitudinal axis of the blank. To enable a radial mixing within the shear zone in addition to the tangential mixing with the lowest possible time and energy input, starting from this method, cylindrical sections of the blank are adjacent to the shear zone on both sides, the first cylindrical section having a first central axis and the second cylindrical section having a second central axis, the first central axis and the second central axis being temporarily non-coaxial with each other.

An automated large outside diameter preform tipping process. A zone of the preform is heated inside a furnace and softened. The preform tip is shaped and the process is controlled by the movement of the glass above and below the heating zone and by sensing the weight of the lower part of the preform, which in effect is a measure of the viscosity of the softened material. Once the correct viscosity is reached, the bottom holder is moved away from the top holder with a non-linear, accelerated velocity profile (derived from the FEM simulation of glass flow) which is precisely programmed and controlled so that the preform tip is optimally shaped (usually short and sharp tipped) with minimum waste and waveguide distortion when drawn into a fiber. The same concept of the non-linear, accelerated velocity profile can also be applied to other tipping processes such as horizontal preform tipping processes.

Disclosed are embodiments of a method of forming a curved glass article. In the method, a mold having a curved surface is provided. A self-adhesive layer is disposed on the curved surface. A glass sheet is bent into conformity with the curved surface at a temperature less than the glass transition temperature of the glass sheet. The glass sheet includes a first major surface and a second major surface in which the second major surface is opposite to the first major surface. The first major surface is adhered to the self-adhesive layer. A frame is bonded to the second major surface of the glass sheet, and the glass sheet is removed from the self-adhesive layer. A system for performing the method and a mold having a self-adhesive layer are also disclosed.

A submerged combustion melter is arranged with a melting chamber, which may be cylindrical, and at least five submerged combustion burners.

A glass cutting line includes automatic remnant storage and retrieval including cutting table with integrated squaring stop and y-break breaking bar facilitating sub-plate cutting. The cutting table is configured for sub-plate cutting mode which provides the ability to cut portions of a stock sheet and release the cut portion in the form of a remnant and or individual workpieces to breakout before the entire sheet is finished scoring without the sub-plate leaving the cutting table.
