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

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.

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.
