Abstract: Plastic preforms are transported during their heating along a predetermined transport path and rotated with respect to their longitudinal axis during transport along a first transport path section to achieve uniform heating of the plastic preforms in the circumferential direction. The plastic preforms remain at least in sections in a predetermined first rotational position with respect to their longitudinal axis during their transport along a second transport path section so that first predetermined circumferential sections of the plastic preforms are heated differently from second predetermined circumferential portions of the plastic preforms. The plastic preforms remain at least in sections in a predetermined second rotational position with respect to their longitudinal axis during their transport along the second transport path section, the first and the second rotational position differing from one another by a predetermined differential angle.

Abstract: 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.
