Abstract

Le dispositif de décoration dans le moule simultanée selon l'invention évite l'utilisation d'un motif présentant des défauts provenant d'une feuille décorative défectueuse et, de ce fait, améliore la production d'articles moulés décoratifs. Pour ce faire, un dispositif d'inspection (10) examine optiquement si le motif (91) de la feuille décorative (71) présente un défaut. Il utilise également une feuille décorative (71a) ayant une marque de défaut (86a) appliquée sur le motif décoratif correspondant (91N). Ce dispositif (1) saute alors ce motif décoratif en se basant sur la marque de défaut afin de ne pas exécuter l'alignement correspondant et d'éviter ainsi l'utilisation du motif défectueux lors d'un transfert dans le moule simultané.
