Abstract (en)
[origin: EP1500480A2] The device comprises: a lower element (2) bearing a lower rest plane (3) for supporting materials to be pressed, the lower rest plane (3) also forming a lower surface of closure of the device; the lower element (2) resting slidably on a lower pressing organ; an upper element (4) which is elastically deformable and provided with at least one active surface (5), which active surface (5) is predisposed to face the lower rest plane (3); a forming frame (6) which projects below a downwards-facing surface of the upper pressing organ and which is predisposed above the upper element (4) and delimits a perimeter of a pressing zone. The forming frame (6) also generates, following a pressing operation, an edge (22) of a final pressed piece (21) which exhibits a greater compaction and therefore a greater density than other zones of the final pressed piece (21). <IMAGE>
