Abstract

A method for temperature conditioning thermoplastic preforms for blow molding. The preforms are guided along a chain path in a transport direction by a plurality of transport and handling means through a heating apparatus. In a heating section, the plurality of heating devices are arranged one after another in the transport direction. On at least one side opposite the heating devices, counter-reflectors are provided, which together with heating devices, form a tunnel-like heating area through which the preforms are transported. In an area of the heating section, a concurrently moving counter-reflector is assigned to each perform or each transport and handling means. The counter-reflectors are guided on a circulating reflector path separate from the chain path, which in the area of the heating section runs parallel to the chain path and in at least one area outside the heating section takes a path route deviating from the chain path.
