Abstract
In a machine such as a press having at least one heating platen and one cooling platen, it is proposed to place between the said platens a variable heat conduction device (22a), when the operation of the machine requires a phase of heating the part without the application of pressure, followed by a phase of cooling the part under pressure. This device (22a) has two thermally conductive plates (32a, 34a), normally separated by a space under vacuum (52a) under the action of at least one deformable member (36a), which can be elastic or plastic. The application of the pressure passes the device (22a) from a thermally insulating state to a thermally conductive state.
