The invention relates to a process for the preparation of bent glazed modules comprising a metal framework and a panel comprising a laminated glazing comprising glass substrates separated by an interlayer made of polymer material, the panel being bent, after the laminated glazing has been assembled, by a force which causes it to take the shape of the metal framework and then held in this shape by a holding means, the bending being carried out while the interlayer is at a temperature between 30 and 80&#xb0; C. The invention reduces the loads necessary for the bending and also the shear stresses between the interlayer made of polymer material and the glass substrates, which reduces the risks of delamination.

Cold bending of a laminated glazing

The invention relates to a glazed module comprising a metal framework and an insulating glazing comprising a water-tight barrier, said insulating glazing being cold-bent, the metal framework and the insulating glazing being rendered integral by a holding means which forces the insulating glazing to retain the bent shape conferred on it by the framework. The invention also relates to a process for the preparation of the glazed module comprising a metal framework and an insulating glazing, the insulating glazing being cold-bent, after it has been assembled with a water-tight barrier, by a force which causes it to take the shape of the metal framework and then held in this bent shape by a holding means.

Cold-bent insulating glazing

A device for cutting a flexible material of plastic type, laminated between two substrates and overhanging the edges of the substrates, includes a cutting tool and a pulling tool arranged upstream of the cutting tool.

Device and method for cutting plastic material, in particular a laminated glazing element

According to this process for manufacturing a laminated glazing unit so that it withstands predetermined stresses, a reference laminated glazing unit is identified that withstands the predetermined stresses and that comprises at least one substrate and one interlayer having the same chemical compositions as those of the laminated glazing unit to be manufactured; the tear strength (J) of the interlayer of the reference laminated glazing unit, and also the interlayer thickness (e) and the substrate thickness (e) of the reference laminated glazing unit are then determined; then, using a graph (C) representative of the minimum interlayer tear strength (J) required so that any laminated glazing unit, comprising at least one substrate and one interlayer having the same chemical compositions as those of the laminated glazing unit to be manufactured, withstands the predetermined stresses, as a function of the interlayer thickness (e) and/or of the substrate thickness (e), a combination of optimum values (e, e) of the interlayer thickness and of the substrate thickness is deduced; the laminated glazing unit is then sized with an interlayer thickness (e) and a substrate thickness (e) that are greater than or equal to the optimum values (e, e).

Process for manufacturing a laminated glazing unit and laminated glazing unit

A process for manufacturing a laminated glazing unit so that it withstands a predetermined load, in which the unit includes at least one substrate having a glass function and at least one layer of polymeric interlayer. The process: obtains viscoelastic behavior of constituent material of the interlayer; calculates maximum value of at least one quantity representative of the loading resistance of the laminated glazing unit subjected to the predetermined load; adjusts dimensions of the unit such that the calculated maximum value of the quantity representative of the loading resistance of the unit is less than or equal to a permissible maximum value; and the or each substrate and the or each layer of interlayer are prepared and assembled to the adjusted dimensions.

Process for manufacturing a laminated glazing unit

A process for manufacturing a laminated glazing, in which a lamination interlayer is interposed between two substrates having a glass function, including: making a measurement of Young's modulus E on a sample of the interlayer, using a viscoanalyzer, by varying temperature and frequency while imposing a constant dynamic displacement; making a numerical treatment of curves obtained, using WLF (Williams-Landel-Ferry) equations, to establish a law E(f) governing behavior of a material constituting the interlayer sample at a given temperature; producing a numerical model based on a finite-element method in bending of a laminated glazing panel, wherein mechanical properties of the sample result from the preceding operations; comparing results of the numerical calculation with those obtained with analytical formulae in which participation of the interlayer in transferring shear in the laminated glazing is represented by a transfer coefficient &#x3c9;; varying the transfer coefficient &#x3c9; in the analytical formulae until results converge; and constructing a transfer function &#x3c9;=f(E) by successive iterations.

A connecting system configured to secure at least one cavity including curved and retaining walls and positioned on a surface portion located on an edge of a substrate made of a fragile material of glass type and a support member. The connecting system includes a shoe including at least one appendage projecting from at least one of faces of the shoe, the appendage having a profile that complements the profile made on the surface portion situated on the edge of the substrate.
