Claim:
A tempering apparatus for tempering plastics material pre-forms for use in a blow molding apparatus for forming containers having non-circular cross-sections, said tempering apparatus comprising a tempering mould located between a heating element and a blowing device of the blow molding apparatus, for tempering an outer wall of the plastics material pre-forms, wherein the tempering mould has at least one first mould part which is movable into contact with a first wall portion of the plastics material pre-form at least for a time, in order to temper this wall portion, wherein the blow molding apparatus has a supply unit for supplying the plastics material pre-forms to the tempering mould, and the supply unit has a holding device for holding the plastics material pre-forms as well as a movement device which, in order to supply the plastics material pre-forms into the tempering mould, produces a relative movement between the plastics material pre-forms and at least one portion of at least one mould part in a longitudinal direction (L) of the plastics material pre-forms, and wherein the movement device orients the preforms with respect to rotational position so that specific areas of wall portions of the preforms are heated more than other portions.
