Abstract (en)

An orifice (23) is provided in the press plug which opens in the plug pressure surface and engages an obturator (25). The obturator is forced to seal during the pressure phase and controlled to open just before the start of the plug removal phase. In this way a pressurized air supply is obtained which is wedged between the briquette and the plug.

Abstract (fr)

Dans le tampon (5) de la presse, il est prévu un orifice (23) qui s'ouvre dans la surface de pression du tampon et qui coopère avec un obturateur (25) ; l'obturateur est forcé en obturation pendant la phase de pression et commandé en ouverture juste avant le début de la phase de soulèvement du tampon, pour obtenir ainsi une alimentation en air sous pression qui se coince entre la briquette et le tampon. <IMAGE>
