Abstract

A heating device for the thermal conditioning of preforms made of a thermoplastic material at a temperature profile that is suitable for a blow molding, and a blow molding machine having such a heating device. The heating device includes a plurality of heating units arranged one behind another along a heating section. The preforms are transported on a transport path along the heating section and along the heating units. The heating section includes a first heating section portion provided with first heating units for the uniform heating of the preforms in their peripheral direction, and a second heating section portion provided with second heating units for the non-uniform heating of the preforms in their peripheral direction. A method for the thermal conditioning of preforms is also disclosed.
