Abstract

L'invention concerne, selon un aspect, une unité de bordage à molette pour bordeuse à molette, qui plie les bords d'un panneau. L'unité comprend: un boîtier; un jeu d'arbres disposé dans le boîtier pour y effectuer un mouvement coulissant longitudinal; un boîtier anti-rotation disposé entre le jeu d'arbres et le boîtier pour guider le jeu d'arbres en coulissement longitudinal et empêcher sa rotation; un support disposé entre le boîtier et le jeu d'arbres et à une extrémité de l'arbre longitudinal du jeu d'arbres; un module capteur de pression disposé entre le support et le boîtier pour détecter la pression appliquée sur le jeu d'arbres; un corps élastique disposé entre le support et le jeu d'arbres pour porter le jeu d'arbres de manière élastique; et une molette disposée sur une autre extrémité du jeu d'arbres pour travailler le panneau, si bien que le contact entre la molette et le panneau peut être maintenu constant, de façon à éviter les défaillances et à neutraliser une force de rotation éventuelle générée au niveau de la molette, par couplage conjugué de douilles cannelées entre le jeu d'arbres et le boîtier anti-rotation, ce qui effectivement réduit au minimum les erreurs de traitement provoquées par la molette.
