Abstract
A die for rotational pressing includes a breather device 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 operated by an actuator piloted by a handling controller 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.
