An apparatus is provided for producing plastic containers, comprising a heating device that heats plastic preforms, and including a shaping device provided downstream of this heating device in the transport direction of the plastic preforms, which shaping device shapes the plastic preforms into the plastic containers, wherein a tempering device for tempering the plastic preforms heated by the heating device is provided in the transport direction of the plastic preforms between the heating device and the shaping device, which tempering device has at least one tempering unit provided on a carrier rotatable about a predetermined rotary axis, and which tempering unit has at least two contacting devices, between which at least one section of the plastic preform can be received, which contacting devices can be moved in relation to one another along a predetermined direction.
A temperature varying device for varying the temperature of plastic preforms, wherein said temperature varying device has at least one temperature varying unit arranged on a carrier which is rotatable about a predefined axis of rotation, and said temperature varying unit has at least two contacting devices which are suitable and intended for contacting an outer wall of the plastic preforms and between which at least one section of the plastic preforms can be received, and having a drive device for moving the at least two contacting devices in a predefined movement direction, wherein the apparatus has a detector for detecting at least intermittently a position of at least one of the at least two contacting devices in the predefined movement direction.
A method for treating containers, wherein a plurality of substantially identical treatment stations are provided which treat the containers in a substantially identical manner by at least one treatment element, and wherein in each case the at least one treatment element is moved relative to the container to be treated by pneumatic drives which are assigned to the individual treatment stations, wherein at least one value which is characteristic of a geometric position of the at least one treatment element relative to the container is detected by a detection device, and/or wherein a first time value is also determined which is characteristic of a reaching of said geometric position of the treatment element and the pneumatic drive is controlled and/or regulated on the basis of said time value.
