The invention provides a curved belt support apparatus (300) that prevents a curved belt (200) from moving inward by supporting a thick part (220) of the curved belt that thickens in both vertical directions at the outer edge of the belt. An upper roller (370) is brought in contact with the upper inside surface (221) of the thick part (220), a lower guide roller (380) is brought in contact with the lower guide roller (380) is brought in contact with the lower inside surface (222) of the thick part (200), and the upper and lower guide rollers are elastically supported such that they can move up and down. When operated, the upper guide roller (370) and the lower guide roller (380) are moved diagonally upward and downward, respectively, in the direction of the radial inner edge of the curved belt so that the thick part (220) of the belt is released from the upper and lower guide rollers.
L'invention concerne un appareil de support à courroie courbe (300) empêchant la courroie courbe (200) de se déplacer vers l'intérieur par support d'une partie épaisse (220) de la courroie courbe qui épaissit dans les deux directions verticales le bord extérieur de la courroie. Un rouleau supérieur (370) est mis en contact avec la surface inférieure interne (222) de la partie épaisse (200), et les rouleaux guides supérieur et inférieur sont supportés élastiquement de manière qu'ils puissent se déplacer verticalement et horizontalement. En fonctionnement, le rouleau guide supérieur (370) et le rouleau guide inférieur (380) sont déplacés diagonalement vers le haut et vers le bas, respectivement, dans la direction du bord radial interne de la courroie courbe de manière que la partie épaisse (220) de la courroie soit libérée des rouleaux guides supérieur et inférieur.
