A method for forming plastic preforms into plastic containers using at least one device for forming preforms into containers, wherein preforms are acted upon by a flowable and, in particular, gas-forming medium and are formed into the containers, wherein the preforms are acted upon with different pressure levels and the flowable medium is stored in at least two reservoirs and is supplied from these reservoirs to the preforms and at least one of these reservoirs is supplied with the flowable medium by a pressure supply device, wherein the target pressure in at least one reservoir is controlled, and wherein this target pressure is compared with an actual pressure in this reservoir. A value characteristic of this comparison is determined. An offset value is controlled on the basis of this value and is controlled in such a way that a predetermined pressure and the target pressure is set in the reservoir.
A method for forming plastic preforms into plastic containers using at least one device for forming plastic preforms into plastic containers, wherein plastic preforms are acted upon by a flowable medium and are thus formed into the plastic containers, wherein the plastic preforms are acted upon with different pressure levels and the flowable medium is stored in at least two reservoirs and is supplied from these reservoirs to the plastic preforms and wherein at least one of these reservoirs is supplied with the flowable medium by a pressure supply device,
An apparatus for forming plastic preforms into plastic containers, having at least one forming station, configured to apply a flowable medium to plastic preforms using an application device and thus form the plastic preforms into the plastic containers, with the forming station applying different pressure levels to the plastic preforms, wherein the device comprises at least a first reservoir configured for storing the flowable medium under a first pressure and a second reservoir configured for storing the flowable medium under a second pressure and at least one supply device is provided, which supplies the flowable medium from these reservoirs to the plastic preforms and further a pressure supply device is provided, configured for supplying at least one of the reservoirs with the flowable medium,
