    摘要: 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

    摘要: Disclosed is a method for the preferential heating of a thermoplastic hollow body having at least one portion to be heated and another to be superheated, the portion that is to be superheated initially having a radiation absorption coefficient substantially identical to that of the portion to be heated. The method includes, in succession: a first step of marking the portions of the hollow body that are to be superheated, during which step isolated marks are made in the thickness of the wall of the portion that is to be superheated so as to increase its absorption coefficient; a second step of preferential heating of the hollow body by uniform exposure of the portions that are to be heated and of the portions that are to be superheated to the heating electromagnetic radiation. Also disclosed is a preform marked in accordance with the first step of the method.

    摘要: A heating station of a container manufacturing installation, the heating station having a plurality of laser emitters wherein each laser emitter includes a plurality of laser chips mounted on an external face of at least one support. In example embodiments, each laser chip includes at least one laser diode arranged to emit laser radiation in the infrared range in an emission direction substantially perpendicular to the external face of the support. In example embodiments, each laser diode includes at least two active regions stacked on one another in the emission direction, wherein each active region participating in the laser radiation emitted by said laser diode.
