| 20110205485 | Procedure and equipment for making glass frames and glass frame obtained therefrom - A procedure for making glass frames obtained from boards made of a plastic or composite material includes a step for deforming a pre-heated single-layer or multilayer board along one or two curvature planes transverse to each other, wherein this deformation step is carried out before the board is milled to create the shape of a glass frame. The equipment suited to implement the above procedure includes a half-mold, an element configured to close the upper opening of the half-mold, and a deformable membrane, wherein the injection of air into an air space causes the expansion of the deformable membrane, which compresses a board against the half-mold, thus deforming the board accordingly. | 08-25-2011 |
