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.

Method of managing preforms immobilized in a heating station

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.

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 &#x3c9;of the rotation of the carrousel and a nominal electrical power setpoint P. The control unit is programmed for: controlling the rotation of the carrousel according to the nominal speed setpoint &#x3c9;. During its acceleration: taking into account the real instantaneous speed &#x3c9; of rotation of the carrousel, and regulating the electrical power of the feed to an instantaneous value P such that:

Disclosed is a processing unit for an electromagnetic processing of plastic parisons and including a series of processing modules, each including a hollow housing, a light emitting assembly and a dehydration circuit for preventing each hollow housing from moisture via a dehydrated fluid. The dehydration circuit extends outside the main body, where the circuit can be in fluid communication with a source of pressurized fluid, on which are disposed a fluid dehydration unit and fluid circulation unit for forcing the dehydrated fluid to feed the respective hollow housings.

Disclosed is a method for controlling a conveyor for conveying hollow bodies through a hollow-body heating station including: &#x2014;a heating tunnel defining a heating path, &#x2014;a conveyor including at least one travel track and shuttles capable of moving along the track while picking up at least one hollow body, the movement of each shuttle being controlled individually, &#x2014;a travel-track loading portion on which two consecutive shuttles move at a first predetermined input separation, and a travel-track unloading portion. Two consecutive shuttles moving on this unloading portion are spaced apart by a predetermined output separation that is different from the first input separation.

The unit () for processing hollow-body plastic blanks () includes a chamber () wherein the blanks () move along a predetermined path. The chamber () is defined, on both sides of the path, by two side walls () having inner surfaces () that face each other. The chamber () includes a main section () wherein at least one of the walls () is provided with a plurality of electromagnetic radiation sources (). The side walls () define therebetween, on at least one end of the chamber, an opening () for the preforms to pass therethrough. The chamber () includes at least one optical confinement section () that extends between the main section () and the opening () and wherein the inner surfaces () of the side walls () are optically reflective and converge toward the opening ().

Conveyor for transporting articles such as a chain conveyor that can be changed between a stretched configuration and a compact configuration, the chain being formed from a plurality of articulated links. Each link includes a trolley provided with lateral guide mechanism cooperating with a track defining a predetermined trajectory, a support carrying a nozzle for the releasable attachment of an article, the support mounted rotatably with respect to the trolley between a straight position corresponding to the deployed configuration of the chain, and an oblique position, corresponding to the compact position of the chain and in which the support is inclined with respect to the straight position; and an actuator coupled to the support, capable of driving the support in rotation from its straight position to its oblique position, and reciprocally.
