    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.

    摘要: Apparatus for producing plastic containers has a heating device having a transport device for transporting the plastic preforms singly along a predefined transport path. The transport device has a plurality of holding devices for holding the plastic preforms, and at least one heating unit for heating the plastic preforms, wherein furthermore a rotating device is provided which rotates the plastic preforms held by the holding devices and is connected to a forming device, which transforms the plastic preforms transported by the heating device into plastic containers. The apparatus has an alignment device which enables alignment of the rotational position of the plastic preforms with respect to their longitudinal direction relative to the holding devices holding these plastic preforms and/or the apparatus has a rotational position alignment device arranged along the transport path which enables alignment of a rotational position of the holding devices with the plastic preforms arranged thereon.
