PROBLEM TO BE SOLVED: To provide a folder gluer for obtaining a corrugated cardboard box high in dimensional accuracy. SOLUTION: A corrugated cardboard sheet is conveyed to a folding part. During the conveyance by the folding part, a first panel and a fourth panel on both sides partitioned by a longitudinal ruled line are folded at 180°along a first longitudinal ruled line and a third longitudinal ruled line formed inside the panels. The lapped parts of the first panel and a joining margin are bonded together to form a flat box A<SB>1</SB>. A pair of molding belts 21 and a pair of inclined sideways approaching belts 22 in contact with the first and fourth panels of the box A<SB>1</SB>are set in the transportation path of the box A<SB>1</SB>. When the width of the box A<SB>1</SB>is larger than a proper value, both side parts of the box A<SB>1</SB>are pressed by the molding belts 21 to be corrected to a proper width. When the width of the box A<SB>1</SB>is smaller than the proper value, the first and fourth panels are moved outside by the sideways approaching belts 22 to correct the width of the box A<SB>1</SB>to the proper width.
