A method for tempering preforms in a blowing machine, wherein at least one heating box is arranged along a transport path for the preforms. The heating box has reflective walls and forms a heating channel through which the preforms are guided. The heating box also has a heater for heating the preforms in the heating channel, and a cooling device, having a blower, for cooling the reflective walls. The walls are cooled by a quantity of air flowing along the walls outside the heating channel. The heating output of the heater is adjustable. A control device provides open loop and closed-loop control of the cooling output produced by the cooling device, in particular the supplied quantity of air, depending on the respective heating output of the heater, depending on a measurement of the heating output. |
