Abstract
A sheet folding device includes forming belts which are disposed on both sides in a transfer direction of a corrugated board and move to a center side in a width direction of the corrugated board toward a downstream side in the transfer direction to press both end portions in the width direction from an outside so as to bend both the end portions; and a gauge roller group including several gauge rollers which are disposed along the transfer direction and come into contact with outer sides of both bent portions in the width direction of the corrugated board bent by the forming belts. In the several gauge rollers, recessed portions are provided on outer peripheral surfaces of the gauge rollers in a circumferential direction. Positions of the recessed portions are disposed to be offset downward in a vertical direction toward a downstream side in the transfer direction.
