A device and a process for the gravity bending of a glass sheet or a stack of glass sheets, referred to as the glass, includes the gravity bending of the glass on a skeleton including a contact rail supporting the glass in the peripheral zone of the lower main face thereof, the contact rail including concave curvatures in each of the sides of the skeleton, a counter-skeleton including a metal bar being present during the bending at a distance d from the edge face or from the peripheral zone of the upper main face of the glass, the peripheral zone of a main face being the zone between the edge of the glass and a distance from the edge of the glass of 50 mm of the main face, d being within the range from 0.1 to 50 mm.

A device for supporting a sheet of glass, in a contact band between the edge and up to 200 mm from the edge of the glass, includes first and second supports that each include a chassis and a support system for supporting the glass connected to the chassis, the support system of each support including a surface for supporting the glass including a fibrous material able to contact the glass in the contact band at a temperature between 400 and 600° C., the two supports being movable in a transfer vertical relative movement enabling the support surface of one to pass over or under the support surface of the other in order to transfer the glass from one support to the other, the support system of the first support including a passage to allow to pass an arm connected to the second support during the transfer vertical relative movement.

A method of forming a glass article includes providing a first glass sheet. The first glass sheet is heated to a temperature suitable for shaping. The first glass sheet is deposited on a first bending tool. An edge portion of the first glass sheet is disposed over a shaping surface of the first bending tool. The shaping surface of the first bending tool is configured to provide in the first glass sheet a compression area and a tension area. The first glass sheet is shaped on the first bending tool and the compression area is formed in the edge portion of the first glass sheet. The compression area includes a first portion and a second portion. The first portion has a width which is greater than a width of a second portion.

A device for annealing glass panes includes rollers for transporting the glass panes and two sets of slit-shaped nozzles, which run parallel to the axes of the rollers and from which cooling air can be directed onto both sides of the glass panes. In the device, cooling air acts as effectively as possible on the two surfaces of the glass pane, and anisotropies and stresses within the glass are reduced. This can be achieved by each nozzle being formed as a continuous flow channel, which extends over the width of the glass panes and on both parallel running sides of which partitions are arranged, for the forming of a flow pocket assigned to this flow channel. The cooling air that comes back from the glass panes is returned between this flow channel and the associated partitions.

A device and a method for bending, by gravity, a sheet of glass or a stack of sheets of glass including a plurality of sides, called the glass, including a skeleton for supporting the glass in its peripheral zone by a contact track, the contact track including concave curvatures on each of the sides of the skeleton, and a counter-skeleton capable of entering into contact with the glass in the zone of the middle of at least one side of the peripheral zone of the top main face of the glass.

The heat resistant separation fabric for use as tool cover in glass processing comprises heat resistant yarns (100). The heat resistant yarns comprise a core (110) and at least one wrap yarn (123, 125). The core is a core yarn. The core yarn is a multifilament glass yarn. The at least one wrap yarns (123, 125) comprises stainless steel fibers. The core yarn is present in the heat resistant yarn without crimp. The at least one wrap yarn is wrapped around the core yarn.

An edge-press molding element is part of a glass-bending tooling that includes a contoured-ring, gasket form factor. The edge-press molding element operates by self-weight bending a glass pane under a thermal load. The glass pane bends under molding conditions where a temperature differential of as low as 30 C. up to 100 C. is achieved between an edge of the glass pane and the center.

A support structure for supporting a heated glass sheet in connection with a bending operation includes a frame, a support ring adjustably supported on the frame for supporting a peripheral portion of the glass sheet, and multiple rib assemblies associated with the frame. Each rib assembly includes a laterally extending rib supported on the frame and multiple spaced apart support members connected to the rib and configured such that at least a portion of each support member is adjustable with respect to the rib. Furthermore, each support member is configured to contact a respective inner portion of the glass sheet to support the respective inner portion of the glass sheet until the glass sheet has been sufficiently cooled.
