Abstract

La invencion se refiere a un metodo para controlar una maquina de moldeo por soplado (18) para fabricar recipientes (12). La maquina (18) comprende un sistema de control (26) y numerosas estaciones de moldeo por soplado (22) y se caracteriza porque el sistema de control implementa iterativamente un ciclo de control que incluye las siguientes fases sucesivas: - una fase de estimacion de la masa de una porcion significativa de cada recipiente (12), - una fase de analisis para comparar la masa estimada con una masa de referencia con el objeto de detectar variaciones de masa; y - una fase de correccion durante la cual los parametros de premoldeo y/o estirado y/o moldeo por soplado son modificados con base en las variaciones de masa.
