Abstract

L'invention concerne la prédécoupe (ou entaillage en vue de la découpe) de verre en feuille continue ou non. L'appareil de prédécoupe comprend un outil de coupe, un groupe appliquant une charge de coupe à cet outil quand celui-ci rencontre la surface du verre à entailler et un organe amortisseur de nature à absorber l'énergie de réaction agissant à l'encontre de la charge de coupe quand l'outil entre en contact avec le verre. L'organe amortisseur a un facteur de perte tg delta assez élevé pour éviter une réduction transitoire sensible de la charge de coupe. L'invention permet d'opérer un entaillage efficace et ininterrompu même lorsqu'on effectue la prédécoupe à grande vitesse.
