A method and machine for obtaining bent glass sheets. Glass sheets are brought to their softening temperature, then they are caused to travel over a shaping bed of advancing elements for advancing them which are arranged along a path having a circular arc-shaped profile, the sheets progressively assuming their shape on entering the bed and over a first shaping zone, then being hardened by tempering or cooling in a second zone of the bed until they leave, and then the bent glass sheets thus obtained are recovered. The shaping bed is produced with a profile extending in a circular arc of more than 90&#xb0;, and, on leaving the shaping bed, the hardened glass sheets are moved in a direction opposite that in which they were fed in.

Method and machine for the production of convex glass sheets

A method for bending a sheet of glass involving heating the sheet of glass to a softening temperature, transporting the sheet of glass in an essentially horizontal path as far as a station for bending the sheet of glass between two forms, shaping the sheet of glass by pressing between the two forms, and cooling the sheet of glass in an appropriate station. Shaped rollers receive the sheet of glass after it has been bent and the rollers are oriented parallel to the direction defined on the sheet of glass by the direction in which it is conveyed into the bending station.

Method and device for bending a glass sheet

A method of acoustically attenuating noises of structure-borne origin in an article of manufacture by installing a laminated window having a glass sheet and an intermediate film, where the film has a loss factor tan &#x3b4; greater than 0.6 and a shear modulus G' smaller than 2&#xd7;10N/min a temperature range between 10 and 60&#xb0; C. and in a frequency range between 50 and 10,000 Hz.

Soundproofing laminated window for vehicles

The invention relates to a soundproofing window in which an intermediate film provides for damping of vibrations transmitted in particular by structure-borne conduction.

A device for cooling bent glass sheets running along a roller conveyor. Blowing boxes are inserted between the rollers and have a surface opposite the glass sheet at a distance of less than 30 mm and preferably less than 10 mm. The surface is perforated with several holes through which air is discharged in the direction of the glass sheets.

Device for cooling convex glass sheets

A window pane fixed to an automobile via a peripheral joint forms at least a part of a wall defining a cabin of the vehicle. The window pane, at the peripheral joint, is constructed so as to eliminate at least one mode of acoustic radiance from the pane to a cavity defined by the cabin when the pane is excited by an acoustic field.
