Abstract: 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.

Abstract: A shaping tool includes a membrane made of a polymer material, the membrane having a shaping surface, and a thermalization system inserted into the membrane. Moreover, a method for constructing a membrane of a shaping tool includes providing a mold with a shape of the membrane to be made and a polymer material that constitutes the membrane; pouring the material into the mold; cross-linking the material; providing a thermalization device and providing a device for increasing thermal conductivity.
