The invention relates to a method for controlling the temperature of preforms consisting of a thermoplastic material. The preforms are to be blow-moulded into containers. The preforms are subjected to a range of temperatures along their periphery and are guided along a translation path, past at least one heating device (14), during the temperature-controlled process. In addition, the preforms are at least occasionally rotated about their longitudinal axes. The control of said rotational movement (8) is, at least at times, carried out independently of the translation movement. The translation movement is controlled in such a way that the peripheral areas of the preforms which are to be subjected to a higher temperature face the heating device for longer periods than the peripheral areas of the preforms which are to be subjected to a lower temperature. Said control has a desired value generator for a temporal modification of the path of the desired value of the rotational speed of the preforms.

L'invention concerne un procédé et un dispositif permettant le tempérage de préformes en matière thermoplastique. Les préformes sont destinées à être moulées en contenants par soufflage. Les préformes sont dotées sur leur périphérie d'un profil de température et, pendant leur tempérage le long d'une section de translation, elles passent à côté d'au moins un dispositif de chauffage (14). En outre, les préformes sont, au moins par intermittence, entraînées en rotation autour de leur axe longitudinal. Une commande du mouvement de rotation (8) est, au moins par intermittence, découplée du mouvement de translation. La commande du mouvement de translation est exécutée de telle façon que les zones périphériques des préformes, à tempérer à une température plus chaude, sont tournées vers le dispositif de chauffage plus longtemps que celles à tempérer à une température plus froide. La commande présente un générateur de consigne pour une évolution variable dans le temps des valeurs théoriques de la vitesse de rotation des préformes.
