    FIELD OF DISSEMINATION
    [0001] The invention relates to a curved panel and a method for its production.
    [0002] In addition to aspects of the equipment, the development of new motor vehicles is also determined, to a large extent, by design elements ("design"). In this the significance of the windshield design is increasing, due to the large, highly visible area. In this regard, not only the appearance of the windshield, but also aspects of energy conservation and environmental impact play a role. Powerful microprocessors, as well as software packages supported by CAD (Computer-Aided Design) also allow for greater adaptation and optimization of the windscreen's aerodynamic resistance. For this reason, modern windshields in motor vehicles have increasingly complex shapes. In particular, motor vehicles with very low fuel consumption, but also sports cars make high demands on panel geometry and thus also on glass panel folding methods necessary for their implementation. The folding of a glass panel can be carried out, for example, by means of a combination of gravity folding and pressure folding. One or a plurality of glass panels are placed in a folding ring and heated. In this process, the glass panel is folded along the geometry predefined by the folding ring with the help of gravity acting on the heated glass panel. The heated glass is then folded into the corresponding shape with the help of negative pressure and a suitable structure.
    [0003] More complex geometries cannot usually be performed with a single bending process. This is made more difficult by the fact that separate or subsequent folding processes cannot be combined in an arbitrary manner. These factors clearly limit the possibilities of obtaining the imagined panel geometry. In particular, the combination of edge bending and surface bending to produce complex geometries can only be accomplished with difficulty.
    [0004] EP 0 677 491 A2 discloses a method for folding and tempering glass panels. The glass panels are heated to their softening temperature, pressed between two complementary shapes in a device, and then transferred to a transport ring. The panels are then tempered and cooled in the transport ring.
    [0005] EP 1 371 616 B1 discloses a device for folding and tempering glass panels. The device comprises, among other things, successive mold carriers, pre-heating sections to heat glass panels to the fold temperature, a gravity-based pre-fold section, a fold section with a press mold and a cooling section.
    [0006] EP 1 358 131 B1 discloses a method for folding glass panels in pairs. For this, the pair of glass panels is pre-folded in a horizontal position on a folding mold in the form of a structure by means of gravity folding. The pair of glass panels is then folded with an entire folding mold surface.
    [0007] US 2008/0134722 A1 discloses a method and device for folding overlapping panels. The panels are lifted by means of a suction mold and pressed by an opposite mold and folded according to the geometry.
    [0008] The purpose of the present invention is to provide a panel that has complex final folds of the surface and edges and can be carried out in a single production process.
    [0009] The purpose of the invention is achieved by means of a device according to claim 1. Advantageous modalities emerge from the dependent claims.
    [0010] A method for producing the panel according to the invention and its use are presented in other independent claims.
    [0011] The motor vehicle glazing according to the invention comprises at least one panel with a panel height of 900 mm up to 1,650 mm seen from the vehicle floor. The panel can be implemented as both single-pane laminated pane. The panel has edges in the region of a roof top edge, an A-pillar edge and a vehicle body edge. The panel comprises two imaginary (virtual) rectangular surfaces A and B. Surface A has dimensions of 800 mm by 800 mm and surface B has dimensions of 1,000 mm by 700 mm. The overlapping virtual surfaces A and B are bounded centrally by means of the lower contact point of the panel with the vehicle body edge horizontal to the floor. The term “horizontal to the floor in a centralized manner” refers to the situation of the panel installed in the vehicle.
    [0012] At the same time, the lowest point of contact and the point of the ceiling top edge located at the shortest distance from the contact point forms an imaginary (virtual) YO centerline. The two furthest points separated based on the width of the panel form an imaginary (virtual) ZO centerline. The complexity of the panel according to the invention is described by the radii of curvature of the panel inside surfaces A and B. The panel has, in relation to the installation situation in a motor vehicle body, vertical radii of curvature from 18 m to 2 m and horizontal radii of curvature from 10 m to 1.0 m in the region of surface A. The panel also has, in relation to the installation situation in a motor vehicle body, vertical radii of curvature from the range of 18 m to 3 m, and horizontal radii of curvature from 10 m to 0.8 m in the region of surface B. At the same time, the curvature of the panel along the virtual center line -YO over the boundary with the top edge of the ceiling corresponds to a first tangent. This first tangent forms an angle (alpha) from -10 0 to +15 0 with the roof surface (vehicle body). Parallel to it the curvature of the panel that touches ZO over the panel boundary with the A-pillar edge corresponds to a second tangent. This second tangent forms an angle 3 (beta) of 28 0 to 70 0 with an imaginary (virtual) ZO centerline. The A-pillar edge means the edge of the panel that faces the A-pillar. The ceiling-top edge means the edge of the panel that faces the ceiling.
    [0013] The panel preferably has vertical radii of curvature from 10 m to 3 m and horizontal radii of curvature from 8 m to 2.0 m in the region of surface A, as well as vertical radii of curvature in the range of 10 m to 4 m and radii horizontal curvatures from 8 m to 1.0 m in the region of surface B.
    [0014] The angle a (alpha) of the first tangent to the ceiling surface is preferably from -5 0 to 10 0 and angle 3 (beta) to the center line - imaginary (virtual) ZO is preferably from 40 0 to 65 °.
    [0015] The height of the panel is preferably 1000 mm to 1250 mm.
    [0016] In an alternative embodiment, the motor vehicle window according to the invention comprises at least one panel with a panel height of 1100 mm up to 1850 mm seen from the vehicle floor. The panel can be implemented as both single-pane and laminated pane. The panel has edges in the region of a roof top edge, an A-pillar edge and a vehicle body edge. The panel comprises two imaginary (virtual) rectangular surfaces A and B. Surface A has dimensions of 800 mm by 800 mm and surface B has dimensions of 1000 mm by 700 mm. The virtual surfaces that overlap A and B are bounded centrally by means of the lowest point of contact of the panel with the edge of the vehicle body horizontal to the floor. The term “horizontal to the floor in a centralized manner” refers to the situation of the panel installed in the vehicle. At the same time, the lowest point of contact and the point of the top edge of the ceiling located at the shortest distance from the point of contact, form an imaginary (virtual) YO centerline. The two furthest points separated based on the width of the panel form an imaginary (virtual) ZO centerline. The complexity of the panel according to the invention is described by means of the radii of curvature of the panel within surfaces A and B. The panel has, in relation to the situation of installation in a motor vehicle body, vertical radii of curvature of 18 m up to 3 m and horizontal radii of curvature from 10 m to 3 m in the region of surface A. The panel also has, in relation to the installation situation in a motor vehicle body, vertical radii of curvature in the range of 18 m to 4 m and radii horizontal curvatures from 10m to 2m in the region of surface B. At the same time, the curvature of the panel along the virtual center line - YO on the limit with the ceiling top edge corresponds to a first tangent. This first tangent forms an angle (alpha) from -20 0 to +15 0 with the roof surface (vehicle body). Parallel to it, the curvature of the panel that touches ZO on the A-pillar edge corresponds to a second tangent. This second tangent forms an angle 3 (beta) from 3 0 to 30 0 with the imaginary (virtual) ZO centerline. The A-pillar edge means the edge of the panel that faces the A-pillar. The ceiling-top edge means the edge of the panel that faces the ceiling.
    [0017] The panel preferably has vertical radii of curvature from 15 m to 4 m and horizontal radii of curvature from 8 m to 4.0 m in the region of surface A, as well as vertical radii of curvature in the range of 15 m to 5 m and radii horizontal curvatures from 8 m to 3 m in the region of surface B.
    [0018] The angle a (alpha) of the first tangent to the ceiling surface is preferably from -10 to 50 0 and / or the angle 3 (beta) of the second tangent to the center line - imaginary (virtual) ZO is preferably from 5 ° to 20 °.
    [0019] The height of the panel is preferably 1250 mm up to 1650 mm.
    [0020] In another alternative embodiment, the motor vehicle window according to the invention comprises at least one panel with a panel height of 1100 mm up to 1,850 mm seen from the vehicle floor. The panel can be implemented as both, such as single-pane or laminated pane. The panel has edges in the region of a roof top edge, an A-pillar edge and a vehicle body edge. The panel comprises two imaginary (virtual) rectangular surfaces A and B. Surface A has dimensions of 800 mm by 800 mm and surface B has dimensions of 1000 mm by 700 mm. The virtual surfaces that overlap A and B are bounded centrally by means of the lowest point of contact of the panel with the edge of the vehicle body horizontal to the floor. The term “horizontal to the floor in a centralized manner” refers to the situation of the panel installed in the vehicle. At the same time, the lowest point of contact and the point of the top edge of the ceiling located at the shortest distance from the point of contact, form an imaginary (virtual) YO centerline. The two furthest points separated based on the width of the panel form an imaginary (virtual) ZO centerline. The complexity of the panel according to the invention is described by means of the radii of curvature of the panel within surfaces A and B. The panel has, in relation to the situation of installation in a motor vehicle body, vertical radii of curvature of 18 m up to 3 m and horizontal radii of curvature from 10 m to 3 m in the region of surface A. The panel also has, in relation to the installation situation in a motor vehicle body, vertical radii of curvature in the range of 18 m to 4 m and radii horizontal curvatures from 10m to 2m in the region of surface B. At the same time, the curvature of the panel along the virtual center line - YO over the limit with the ceiling top edge corresponds to a first tangent. This first tangent forms an angle (alpha) from -20 0 to +15 0 with the roof surface (vehicle body). Parallel to it, the curvature of the panel that touches ZO on the A-pillar edge corresponds to a second tangent. This second tangent forms an angle 3 (beta) from 3 0 to 30 0 with the imaginary (virtual) centerline - ZO. The A-pillar edge means the edge of the panel that faces the A-pillar. The ceiling-top edge means the edge of the panel that faces the ceiling.
    [0021] The panel preferably has vertical radii of curvature from 15 m to 4 m and horizontal radii of curvature from 8 m to 4.0 m in the region of surface A, as well as vertical radii of curvature in the range of 15 m to 5 m and radii horizontal curvatures from 8 m to 3 m in the region of surface B.
    [0022] The angle a (alpha) of the first tangent to the ceiling surface is preferably from -10 to 50 0 and / or the angle 3 (beta) of the second tangent to the center line - imaginary (virtual) ZO is preferably from 5 0 to 20 °.
    [0023] The height of the panel is preferably 1250 mm up to 1650 mm.
    [0024] The method for folding panels according to the invention makes it possible to combine edge folding as well as surface folding. In this way the realization of the geometries and radii of curvature of the panel according to the invention and of the two alternative modalities of the panel according to the invention, is possible. The final geometry depends on the geometry of the motor vehicle (vehicle body) and can be calculated and simulated in a conventional manner by the person skilled in the art using CAD programs. The method comprises a first step in which at least one panel, preferably a first panel and a second panel are placed in a pre-folding ring on a movable folding ring holder. The method is suitable for both a panel and for folding panels in pairs. The pre-folding ring preferably has a fold with an average final edge fold of 5% to 50%. The movable folding ring holder then moves to an oven, and the panels are heated in the pre-folding ring by means of a heating device, at least to the glass softening temperature, preferably 550 ° C to 800 ° C The softening temperature is determined by the composition of the glass. The panels placed on the pre-fold ring are pre-folded by gravity to 5% to 50% of the final local edge fold. In the context of the invention, the term "final edge folding" is the average (final) folding in the final finished state of at least a portion of the panel edge or edge of the folding ring with a dimension or length of at least 30% of the full folding ring edge or panel edge. The panels are lifted in the next step by a suction device and folded even further than the fold obtained in the pre-fold ring. The panels are preferably folded to 102% to 130% of the final edge fold. The folding takes place on a counter structure located in the suction device. The counterframe is preferably ring-shaped with a protruding folded contact surface. The suction device includes, in addition to the counterframe, a cover with an air baffle surrounding the counterframe. The air baffle is located adjacent to the raised panel and is designed in such a way that during folding on the contact surface of the counter structure the panel is at a distance of 3 mm to 50 mm from the air baffle. This distance allows continuous aspiration of air in the intermediate space between the panel and the air baffle. The air drawn in generates a negative pressure to fix the panel on the contact surface. The suction process bends the panels corresponding to the bending (curvature) of the contact surface. The contact region of the molded part, in particular the contact surface with the panel, is preferably coated with a flexible or soft material. This material preferably includes fire-resistant glass fibers, metal or ceramic, and prevents damage such as scratching on the panels. The description of the mode of operation and structure of the suction device for lifting the panel is found in US 2008/0134722 A1, [0036] and [0038] to [0040] as well as claim 1a. The panels are then placed via the suction device in a final folding ring on the movable folding ring holder. The final fold ring preferably has at least an average final fold 30% greater than the pre-fold ring. The placement of the panels can take place, for example, by raising the suction pressure by means of a pressure drop of the suction device. The pre-folding ring and the final folding ring are, in each case, folded according to the projected panel geometry. The circumference and opening angle of the folding ring are adapted to the geometry of the panel to be folded. The pre-folding ring and the final folding ring are preferably placed on the same movable folding ring holder and can, for example, be converted by removing a pin or a pre-folding ring holder for the final folding ring. In the context of the invention, the term “convert” means both changing the shape (geometry) of the folding ring from the pre-folding ring to the final folding ring and withdrawing the pre-folding ring as well as “making it accessible ”A final folding ring placed below the pre-folding ring. The panel placed on the final folding ring is pre-folded by means of thermal radiation on the surface. For this, a temperature gradient is set above the panel and different surface folding is made possible by different heating. The heating device preferably includes an arrangement of individually controllable heating tiles separately. As a result of the different thermal radiation of the tiles, different temperature regions can be carried out on the panels. The panels are then lifted by a second suction device. The second suction device preferably has the same structure as the first suction device. In the next step the panels are pressed against a countermold and preferably folded on the surface of the panel. The structure of this countermold is described in US 2008/0134722 A1 in [0037] and figure 2. The countermold functions as a negative of the folded surface of the panel and folds the panel to the final surface geometry. Then the panels are placed over the final folding ring and cooled.
    [0025] The panels preferably include glass, particularly preferably flat glass (float glass), quartz glass, borosilicate glass and / or sodium-calcium glass.
    [0026] The panels are preferably lifted by means of the suction device and folded to 100% to 130%, preferably to 105% to 120% of the overall final edge fold. The term “final overall edge bend” refers to a uniform bending of the entire panel expressed as a percentage. The panels are preferably formed on a folding ring (against structure) in the suction device in such a way that they have an edge fold that exceeds in shape or extension the amount of the final edge fold.
    [0027] The panel is preferably folded by means of the suction device with a final fold locally different from the edge. The term “local end edge fold” refers to a non-uniform (end) fold (of the edge) of the entire panel expressed as a percentage.
    [0028] The panel is preferably folded in a localized manner in the first and / or second suction device by means of an air flow or a lower folding ring. The term "locally" means individual regions of the panel, to which an additional fold is adjusted in a limited region by means of an air stream, preferably from a nozzle. Alternatively, the described local folding can take place by means of a folding ring applied from below.
    [0029] The panels are preferably heated by means of a temperature gradient over the glass surface with a maximum of 0.05 K / mm to 0.5 K / mm, preferably 0.1 K / mm to 0.2 K / mm. The adjustment of the temperature gradient takes place preferably by means of heating devices controlled in a different way (i.e., different amounts of radiated heat) and placed above or below the panels.
    [0030] The panels are preferably heated to a temperature of 500 ° C to 750 ° C, in particular, preferably 780 ° C to 650 ° C.
    [0031] The panels are preferably pre-folded by means of gravity in the pre-fold ring for 10% to 30% of the final average fold.
    [0032] The suction device preferably accumulates a suction pressure from 1 kg / m2 to 100 kg / m2. This suction pressure is sufficient to securely attach the panels to the suction device and fold them over the counterframe.
    [0033] The invention also includes a panel, in particular a pair of panels, folded using the method according to the invention.
    [0034] The invention further includes the use of the dashboard according to the invention as a motor vehicle windshield.
    [0035] The functional regions of surfaces A and B serve in all modalities of the invention in the area of transmission optics, cleaning capacity with windshield wipers and suitably as a surface for HUD (head-up-display) . On surfaces A and B, the radii of curvature according to the invention allow optimized properties of the mentioned characteristics.
    [0036] The transitions according to the invention in all embodiments of the invention allow a reduction in wind resistance by minimizing edge. The transitions according to the invention in the A-pillar region reduce noise generation.
    [0037] In what follows the invention is explained in detail with reference to drawings and a modality taken as an example as well as a comparative example. The drawings are purely schematic and are not to scale. They do not limit the invention in any way.

The pre-fold ring 7a and the final fold ring 7b can be obtained, for example, by removing a pin or a support from the pre-fold ring 7a for the final fold ring 7b. An intermediate region C for heating the panels 1, 2 placed on the final folding ring 7b connects to the suction device 5 in the pre-folding region B.

The corresponding final fold can be produced in the panels 1, 2 taken by means of the suction device folded in a convex manner 15 by means of a horizontally and vertically folded counter-concave mold 16. The panels 1, 2 are pressed between the suction device folded in a convex manner 15 and the counter mold folded in a concave manner. To increase the cycle speed, yet another third suction device 17 can be installed in addition to the convexly folded suction device 15. The third suction device 17 can pick up panels while panels are being folded in the second suction device.

The contact surface 12 of the counterframe 8 with the second panel 2 is preferably coated with a flexible or soft material, such as or fire-resistant glass fibers, metal or ceramic.
    [0048] Figure 3 outlines a flow chart of the method according to the invention. Two panels 1, 2 are placed on a pre-folding ring 7a on a movable folding ring 3. The folding ring 3 is then transported into an oven. The panels 1, 2 are heated by a heating device 6 which consists of irradiation heating elements to the softening temperature of the panels 1, 2, roughly 580 ° C to 650 0 C. During the course of heating the panels 1, 2, the panels 1, 2 located in the pre-folding ring 7a are pre-folded with the aid of gravity to 5% to 40% of the average final fold to be obtained. The heating device preferably comprises an arrangement of individually controllable heating tiles separately. As a result of the different thermal radiation of the tiles, different temperature regions can be carried out on the panels 1, 2. The different temperature regions allow a gradual heating of the panels' surface. The panels 1, 2 are then lifted by means of a preferably convex suction device 5 and folded to 102% to 130% of the average final fold.

For this, a temperature gradient is set above panels 1, 2 in the intermediate region C, and different surface folding is made possible by different heating. The heating device 6 preferably includes an arrangement of separately controlled individual heating tiles. As a result of the different thermal radiation on the tiles, different temperature regions can be carried out on the panels 1, 2. Then, the panels are raised in the final folding region D by means of a second suction device 15 and pressed against a counter preferably concave mold 16 and shaped. The countermold has an inverted geometry compared to the second suction device 15. Then the panels 1, 2 are placed on the final folding ring 7b and cooled.
