摘要： A corrugated cardboard sheet feeding apparatus, which comprises: an upstream-side conveying unit which conveys a corrugated cardboard sheet mounted on delivery rollers; and a downstream-side conveying unit which is adjacent to the downstream side of the upstream-side conveying unit and conveys, to a sheet processing unit, the corrugated cardboard sheet delivered from the upstream-side conveying unit. The downstream-side conveying unit has: a downstream-side suction unit which has openings facing a sheet conveyance path; and feed rollers with a portion of the outer peripheral surfaces thereof protruding towards the sheet conveyance path, which are accommodated in the downstream-side suction unit. The distance between the downstream ends of the openings and the axis of the most-downstream-side delivery rollers is set to be not larger than the maximum range of the distance between the conveyance rollers of the sheet processing unit.

摘要： 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.
