• the document JP 2009 249838 exposes another configuration.
• the present invention aims to provide a manufacturing method in which, unlike the prior art, the orientation of the glass in space during the fixing of the means enabling its mobility is not important.
• the present invention aims to provide a manufacturing method in which the precision of fixing the means enabling the mobility of the window is very high, in particular along the Y axis of the vehicle; A tolerance of plus or minus 0.5 mm along the Y axis can be obtained thanks to the present invention on the final glazing whereas before the fixing of the window holder there may be a significant gap, on the order of 1.5 to 2 mm between the window holder and a face opposite the window.
• the present invention is based on the idea of very quickly creating a mechanical hold for the glass holder inside the U-shaped part, when the glass holder is positioned in the appropriate position with respect to the glass, while the chemical fixing of the glass holder to the glass is being carried out using the usual glue.
• the present invention further intends to propose a method for the mass production of glazing with a single adhesive material which is faster than previously, in particular a method for which it is not necessary to wait for the complete polymerization, drying or hardening of the adhesive to remove the glazing from the reference frame which serves to fix the means enabling the mobility of the glass.
• the present invention aims to provide glazing in which the means enabling its mobility are fixed in a more precise manner and which, moreover, cost less to manufacture because it was manufactured faster.
• the present invention further intends to offer a glazing which, in a surprising way, integrates in its fixing zone(s) flexible material: foam strips; at first glance, the use of a flexible material appears incompatible with the goal of a reliable and efficient fixing but, as proposed, it makes it possible to create a compensation region for the different expansion coefficients of the different materials used for the glazing and for the means allowing its mobility.
