Abstract
The invention concerns a method for managing captive preforms immobilized in a heating station during an interruption of production, the preforms following a production stream, the heating station including a device for conveying preforms and a heating cavity bordered by at least one row of emitters of monochromatic electromagnetic radiation. The method consists in ejecting from the production stream the cold captive preforms that have been immobilized before they have been exposed to the electromagnetic radiation emitted by the emitters to a recycling stream and rejecting from the production stream the hot captive preforms that have been at least partly exposed to the electromagnetic radiation emitted by the emitters to a reject stream separate from the recycling stream.
