Abstract
La pièce de fermeture 4 est constituée de deux parties, la partie 4a, côté bloc et récepteur de bloc et la partie 4b, côté plaque de pression 3. Ces deux parties 4a et 4b s'appuient l'une contre l'autre lorsque la presse est sous pression mais sont séparées par un joint d'air 15, sous l'action de ressorts 16, lorsque la presse n'est pas sous pression.
