PROBLEM TO BE SOLVED: To bend a plurality of kinds of corrugated cardboard sheets of special shape and size using one bending apparatus. SOLUTION: Folding panels 3a, 3b are folded by folding belts 26 while allowing the driving side and operating side folding belts 26 to travel in a direction of an arrow mark synchronously with the conveying speed of the corrugated cardboard sheet 3. The folding operation of the folding belts 26 is assisted by a folding bar 48. When one folding panel 4a folds up the corrugated cardboard sheet 4 of special specification long in a machine width direction, a driving side pulley 37 in a process of interfering with the folding panel 4a is lowered downward to rehang the driving side folding belt 26 on pulleys 76, 77. An additional folding bar 80 folds up the folding panel 4b instead. Further, a long folding bar 48 is replaced with a short folding bar 78. COPYRIGHT: (C)2011,JPO&INPIT |
