<p>The pressing machine comprises at least one die (1) having a number of intercommunicating chambers (2) containing incompressible fluid (F) and closed by an elastic membrane (12) having an external surface that reproduces the rear of the tile (41) and an internal surface anchored to walls (208) separating the chambers (2). Inside each chamber (2) there is inserted, in an intermediate position between the fluid (F) and the membrane (12), an element (4) for controlling the deformation of the membrane (12). The control element is anchored to the membrane (12) and has a zone close to the membrane (12) a certain distance from the walls so as to define, in the membrane (12), a perimetric elastic joint (12a) connecting the control element to the respective walls (208). The control element cooperates with respective positioning members (14) that maintain each control element in a predetermined position within the relative chamber (2) during the forming of the membrane (12).</p> |
