Abstract

L'invention permet de détecter correctement le minutage d'arrivée de paraisons dans un moule d'ébauche, et d'exclure ainsi de manière sûre les articles défectueux produits du fait d'un dérèglement du minutage d'arrivée. Un capteur laser est disposé de manière à ce que son axe lumineux passe au travers d'un trajet de paraisons situé entre le moule d'ébauche et une sortie de déflecteur de chaque section d'un appareil de formage IS. Un moyen de traitement qui traite des signaux de blocage de lumière du capteur laser, détecte le minutage d'arrivée des paraisons pour chaque section sur la base de ces signaux de blocage de lumière du capteur laser, et lorsque ce minutage d'arrivée s'éloigne d'une plage prédéfinie, les articles formés à partir des paraisons en question sont exclus par mise en action d'un moyen d'exclusion.
