    摘要: An apparatus for forming plastic preforms into plastic containers, has a plurality of forming stations each having application devices that apply the plastic preforms with a flowable and gaseous medium for their expansion. The apparatus has at least one first compressed air reservoir configured to store compressed air at a first predefined pressure. Each forming station has a valve arrangement with a plurality of valve devices configured to apply the plastic preforms with at least two pressures, wherein at least one of the valve devices is a pneumatically-controlled valve device. This valve device has a working chamber for receiving gaseous medium, used to act upon the plastic preforms, and a valve piston that can be moved between at least two positions. The valve device further has a control chamber that can be applied with a gaseous control medium for moving the valve piston.

    摘要: An apparatus for forming plastic preforms into plastic containers has at least one supply device with at least one first connecting line, wherein at least one section of at least one connecting line is arranged stationary relative to a main carrier by at least one fastening device, and wherein a section of this connecting line is arranged on a device of the forming device in such a way that, in the event of a movement of the side part carrier relative to the main carrier, this section of the connecting line moves relative to the fastening device. An actuator is arranged on the apparatus, to which at least a section of the connecting line is fastened, wherein this actuator also being movable relative to the main carrier.

    摘要: 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.
