Abstract

A rotary-type furnace for conditioning preforms with a heating wheel at which several heating modules for heating one preform each are arranged, wherein the heating modules are each a heating chamber and a holding device for the preform. The furnace has a lifting device for lifting and lowering the holding device and/or the heating chamber to change between a loading or withdrawal position, in which the preform does not overlap with the heating chamber in the direction of its main axis, and a radiation position in which a section of the preform is arranged within the heating chamber, a particularly quick and reliable transfer from an infeed starwheel can be realized.
