Abstract
A heating apparatus that includes a plurality of heating devices for temperature conditioning of preforms made of a thermoplastic material to a temperature and temperature distribution suitable for blow molding, and a transport chain guided on a revolving chain path. The preforms are transported through the heating apparatus by the transport chain along a transport path. Along a heating section that is part of the transport path, the plurality of heating devices are stationarily arranged one after another in a transport direction. On at least one side facing the heating devices, counter reflectors are provided, which together with the heating devices form a tunnel-like heating area through which the preforms are transported for heating. At least one counter reflector travels along with the preform through the heating section.
