    Abstract: A facility for the production of containers from blanks, which facility includes: a forming unit equipped with a rotating carrousel driven by a motor; a unit for heating blanks, equipped with infrared emitters and a power feed for each emitter; a control unit having in the memory a nominal speed setpoint ωN of the rotation of the carrousel and a nominal electrical power setpoint PN. The control unit is programmed for: controlling the rotation of the carrousel according to the nominal speed setpoint ωN. During its acceleration: taking into account the real instantaneous speed ω of rotation of the carrousel, and regulating the electrical power of the feed to an instantaneous value P such that: P  ( t ) = P N · ω ω N

    Abstract: The invention relates to a method for controlling confined preforms which are stopped in a heating station during a production interruption, the heating station comprising a device for conveying preforms comprising individual supports which move in a closed circuit and a heating cavity which is bordered by at least one row of transmitters of monochromatic electromagnetic radiation. The method includes a step of heating, by the transmitters of the heating cavity, the confined preforms referred to as “cold” preforms which have been stopped before being exposed to the electromagnetic radiation emitted by the transmitters.

    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.
