1. An apparatus for producing plastic containers, having a heating device fir heating plastic preforms, wherein the heating device has a transporting device configured to transport the plastic preforms individually along a predetermined transport path, and this transport device has a plurality of holding devices configured for holding the plastic preforms, and at least one heating unit is provided configured to heat the plastic preforms, wherein further a rotating device also being provided, configured to rotate the plastic preforms held by the holding devices during their transport through the heating device with respect to their longitudinal direction, and with a forming device configured to form the plastic preforms transported by the heating device into plastic containers, wherein this forming device has at least one forming station configured to form the plastic preforms into the plastic containers by the action of a flowable medium,
wherein
the apparatus has an alignment device configured to align 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 which is arranged along the transport path and which is configured to align a rotational position of the holding devices with the plastic preforms arranged thereon
wherein the heating device has an adjusting device configured to adjust a rotational position of the plastic preforms and the adjusting device has at least two guide curves, which are arranged one after another along the transport path of the plastic preforms, and
wherein at least one guide curve is adjustable in order to change the rotational position of the plastic preform.
