Beschreibung
Zusammenfassung:	The present invention relates to a continuous or discontinuous linear system for heating the preforms upstream of a blowing or stretch- blowing machine, in particular a heating system by means of infrared radiation generated by one or more monochromatic laser sources (L1).In particular, the invention relates to a continuous or discontinuous apparatus (1, 501) of the linear type for heating preforms (P), comprising a plurality of heating devices configured so as to be arranged outside the preform and to radiate an electromagnetic radiation in the infrared range forming, in such a heating element, a radiation disk according to a radial symmetry with respect to the center of the preform axis.
