description | The apparatus (1) has a clean room (20) having a blow station (8) which comprises a blow mold for shaping the plastic preforms (10) using process pressure. A venting device is provided for venting the process pressure or reducing the process pressure to recovery pressure in atmosphere. The venting device has a venting valve through which the process pressure or the recovery pressure is vented into the atmosphere through a sound absorber. A pressure drop safety device is provided on the venting device for closing the venting valve before the atmospheric pressure level is reached. An independent claim is included for method for molding plastic preform into plastic container. |
