A bending station for a bending device, includes two bending molds, a pressing frame arranged to adapt to the glass sheet and to press it against an upper mold, the upper mold including a molding face, the area of which, defined by projecting the contour of the upper mold onto a horizontal plane, is greater than the area defined by projecting the outer contour of the pressing frame and the glass sheet onto the same horizontal plane, the pressing frame including a pressing ring having a continuous surface, the upper mold including a flexible sheet associated with an upper series of translational elements, wherein the upper mold is able to deform under the effect of the translational elements of the upper series in order to obtain a deflection value varying by at least 5 mm.
A bending station for a bending device, comprising two bending molds comprising a pressing frame and a solid and uniform upper mold, the pressing frame arranged to adapt to a glass sheet and to press the glass sheet against the solid and uniform upper mold, the pressing frame comprising a pressing ring having a continuous surface, the upper mold comprising a flexible sheet associated with an upper series of translational elements, wherein the upper mold comprises a molding face formed by a pressing surface of the flexible sheet, wherein an area of the molding face, defined by projecting a contour of the upper mold onto a horizontal plane, is greater than an area defined by projecting an outer contour of the pressing frame and of the glass sheet onto the same horizontal plane, and wherein the upper mold is adapted to deform under the effect of the translational elements of the upper series in order to obtain a deflection value varying by at least 5 mm, wherein each translational element has a principal actuation axis and a distal end, the distal end being slidably coupled to the flexible sheet by a compensation interface configured to transmit force along the principal actuation axis while permitting relative displacement between the distal end and the flexible sheet by sliding along at least two different directions lying in a plane transverse to the principal actuation axis.
