Method and apparatus for managing stationary preforms in heating station

The invention relates to a method for managing retained preforms (12) immovable in a heating station (10) during a production interruption, the preforms (10) passing along a production flow (P), the heating station (10) comprising:-a transport device (14) of the preforms (12),-a heating chamber (30) at the edge of which at least one row of monochromatic electromagnetic radiation emitters (32) is arranged; characterized in that the management method consists in discharging the so-called "cool" detained preforms, which are still before exposure to the electromagnetic radiation emitted by the emitter (32), from the production stream (P) to the recovery stream (42), and discharging the so-called "heat" retained preforms, which have been at least partially exposed to the electromagnetic radiation emitted by the emitter (32), from the production stream (P) to a waste stream (38) separate from the recovery stream (42). 本发明涉及一种管理在生产中断期间在加热站(10)中不动的滞留的预成型件(12)的管理方法，预成型件(10)沿生产流(P)通过，加热站(10)包括：-预成型件(12)的传送设备(14)，-加热腔(3
