Abstract (en)
[origin: WO2022195204A1] The present invention relates to a bending station (4) for a bending device comprising two bending forms, a pressing frame (5) arranged to fit the glass sheet and press it against an upper form, the upper form (6) comprising a forming face in which the area defined by the projection of the contour of the upper form on a horizontal plane is greater than the area defined by the projection of the outer contour of the pressing frame and the glass sheet on the same horizontal plane, the pressing frame (5) comprising a pressing ring (50) having a continuous surface, the upper form comprising a flexible sheet (60) associated with an upper series of translation elements (70), characterised in that the upper form is capable of deforming under the effect of the translation elements of the upper series to obtain a bend value varying by at least 5 mm.
