Beschreibung
Zusammenfassung:	The present invention relates to a heating system for preforms upstream of a blowing or stretch-blowing machine, in particular a heating system using monochromatic infrared radiation, preferably laser-generated.In particular, the invention relates to a heating system (301) for preforms (P), comprising a carousel for treating the preforms (P) comprising a plurality of heating elements (304) configured to be inserted either inside or outside each preform (P) and to radiate electromagnetic radiation in the infrared field which forms, in such a device, a disc of radiation according to a radial symmetry which departs from the center of the axis of the preform and which appropriately converges and diverges.
