A method of fabrication of a laminated glazing unit, includes cutting out a first through-hole in a first glass sheet; positioning a conducting wire and a film of thermoplastic polymer between the first glass sheet and a second glass sheet so that a first extremity and a second extremity of the conducting wire extend outside the laminated glazing unit to be formed, and feeding out the first extremity of the conducting wire via the first through-hole so that the first extremity exits the laminated glazing unit to be formed via the first through-hole, the conducting wire extending continuously from the first extremity to the second extremity, and after the positioning and feeding out, assembling the conducting wire, the film of thermoplastic polymer, the first glass sheet and the second glass sheet all together to form the laminated glazing.

Manufacturing process for laminated glazing unit

The method includes tracing a score line on the surface of the glass, using a scoring tool, and breaking out using a local pressure system applied on the opposite face and opposite the score line, the local pressure system being moved and pressed along the score line on the opposite face.

Method for breaking out a sheet of glass

The process relates to the manufacture of a plurality of glazings of complex shape from a rectangular sheet of float glass of large dimensions. The process includes at a first station for cutting the glass sheet, scoring at least one cutting line corresponding to at least one ready-to-shape edge of the glazings; a first breaking operation; at a second cutting station, scoring at least one cutting line corresponding to at least one other ready-to-shape edge of the glazings, and a second breaking operation.

Process for manufacturing glass sheets of complex shape

A laminated glazing unit including a first and a second glass sheet, the first glass sheet being equipped with a first through-hole, a spacer film of thermoplastic polymer disposed between the first and second glass sheets, at least one conducting wire buried within the spacer film or disposed between the spacer film and the first glass sheet or disposed between the spacer film and the second glass sheet, one end of each conducting wire exiting from the laminated glazing unit via the first through-hole in the first glass sheet. The conducting wires are fed through a laminated glazing unit, with a guaranteed quality of positioning of the conducting wires, an improved field of view and with no induced noise.

Laminated glazing unit

A grinding wheel is suited for shaping glass, notably glass that is less than or equal to 4 mm thick. This grinding wheel has at least one abrasive portion formed of at least one metal binder and of diamonds distributed in the binder. The binder has a Rockwell B hardness of between 95 and 105 and is tungsten-based. The diamonds have a size of between 75 and 95 &#x3bc;m and a concentration of between 2.2 ct/cmand 2.64 ct/cm. Glass, in particular for shaping motor-vehicle glazing units, can be shaped with this grinding wheel, making it possible to achieve travel speeds greater than or equal to 30 m/min.

Grinding wheel for shaping flat glass

The invention relates to a process for manufacturing a printed laminated glazing unit composed of two glass sheets separated by an interlayer adhesive sheet, comprising the steps consisting in screen printing, with a printing composition, at least one face of one of the sheets making up the glazing unit using a screen printing screen; and in assembling the various sheets making up the glazing unit, at least one of which has been screen printed. In this process a screen printing screen is used that comprises two superimposed fabrics, the fabric (I) intended to be placed opposite the face to be screen printed having a smaller mesh opening than the other fabric (S), the difference in mesh opening between the two fabrics lying in the range from 22 to 65 &#x3bc;m.
