A die for rotational pressing includes a breather device (12, 112) for connection of the interior of the die with the exterior and which has a passage between the interior and the exterior of the die equipped with a valve (13, 113) operated by an actuator (14, 114) piloted by a handling controller (22, 122) for opening the passage after a first step of the pressing process. The valve allows the breather of the internal pressure of the die and/or controlled injection of air under pressure into the die. |
