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
