PROBLEM TO BE SOLVED: To effectively prevent warpage which occurs in a double-faced corrugated cardboard sheet.;SOLUTION: An apparatus for preventing warpage of double-faced corrugated cardboard sheet comprises: a conveyance part 2 which moves a belt 34 in a predetermined direction while allowing the belt 34 to contact a top surface of a single-faced corrugated cardboard sheet D in manufacturing a double-faced corrugated cardboard sheet E by adhering the single-faced corrugated cardboard sheet D, which is made up of a core B and a rear liner C, to a front liner A; a heating part 3 which is provided below the conveyance part 2 and contacts a bottom surface of the front liner A; a plurality of pressing parts 4 which are arrayed in a moving direction of the belt 34 and in a width direction orthogonal to the moving direction, and applies pressing force toward the heating part 3 via the belt 34 of the conveyance part 2; and a control part 5 which controls the pressing parts 4 so as to make allocation of the pressing force in the width direction different between an upstream side and a downstream side of the moving direction of the belt 34.;COPYRIGHT: (C)2015,JPO&INPIT
