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 pre-form 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 pre-forms with different pressures, wherein at least one process valve is configured for producing a connection between the plastic preform and an environment.

Abstract: A method for forming plastic preforms into plastic containers, wherein the plastic preforms being transported along a predetermined transport path and being acted upon and expanded by a flowable medium during this transport, a controllable valve of a reducing station controlling the action of the flowable medium on a compressed-air reservoir, in particular an annular channel, and a desired target pressure being predetermined, with which the compressed-air reservoir is acted upon, this desired target pressure being taken into account in the control of the valve of the reducing station wherein an actual pressure is determined and this actual pressure is compared with the desired target pressure and, from this comparison, a correction value is determined which is taken into account and/or used in the control of the valve.

Abstract: Method for operating an apparatus for forming plastic preforms into plastic containers, wherein in a working mode a plurality of forming stations are moved along a predetermined transport path by a movable carrier, wherein these forming stations in each case having blow mould arrangements which in a closed state in each case form cavities, within which the plastic preforms are formed into the plastic containers and the plastic preforms are supplied to these forming stations in order to be formed by supplying a flowable medium to the plastic containers, wherein this forming takes place at least temporarily during the transport of the forming stations along the transport path, and wherein at least temporarily at least components of the blow moulding arrangement are tempered. At least parts of the blow mould are pre-heated in a standstill of the carrier or a movement of the carrier, which is slower with respect to a movement of the carrier in the working mode.
