    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.
