PURPOSE: A manufacturing device of a corrugation pad type corrugated cardboard is provided to improve the buffering and machining properties for smooth curve or corner portions, thereby improving the appearance, and improve the stability of a good to be wrapped by the corrugated cardboard by properly dispersing and absorbing the external impact through the multi-stepped shape. CONSTITUTION: A manufacturing device of a corrugation pad type corrugated cardboard includes a first machining unit(10) having a pair of conveying rollers(2,4) oppositely mounted to a supporting frame(A) for supplying a first base sheet(1) in sequence, a molding roller(5), of which an outer periphery is machined in the shape of corrugation core, to be driven for bending the supplied base sheet in the shape of sine or non-sine type corrugation, an adhesive agent to be doped on protruded portions of the base sheet, a pressing roller(7) mounted facing the molding roller for integrating the corrugated sheet with a base sheet by the corrugation portions doped with the adhesive agent, and a winding roller(9) for recovering the corrugated cardboard(8), a second machining unit for winding the corrugated cardboard inwardly at the corrugation portions, wherein the corrugation portions are adhered to an outer surface of the base sheet by doping the adhesive agent, a third machining unit for pressing the corrugated cardboard in a desired shape, and a fourth machining unit for connecting and assembling a plurality of such a corrugated cardboard.
