Abstract

Apparatus for forming plastic preforms into plastic containers, having a forming device which has a plurality of forming stations each having a stretching bar for stretching the plastic preform and an application device act upon the plastic container with a flowable medium. The forming device has at least four pressure reservoirs for the flowable medium, which each have predetermined pressures, and a valve block with at least five process valves. The application device is configured for producing a fluid connection between the valve block and a mouth region of the plastic preform in order to act upon the plastic preforms with the pressurised flowable medium, and the process valves are configured to act upon the plastic preforms with different pressures, wherein at least one process valve is configured for producing a connection between the plastic preform and an environment.
