A manufacturing device of a curved tube curvature for a seam type duct formed flange is provided to prevent poor quality of the task efficiency by manually when molding an upper and lower panel of the duct in which a flange and a seam part are formed to curvature. A manufacturing device of a curved tube curvature for a seam type duct comprises a vertical plate installed at both sides of a base(1) with standing erect; a first forming roller is installed between the vertical plates in which a plurality of first receiving portions(4) is formed so that the second deep part be inserted; a plurality of first holding portions(3) is installed between the above-described vertical plate and is protruded to the constant interval so that the side part of the duct In-line lower plate be supported; a first forming roller in which a plurality of first receiving portions is formed so that the second deep part be inserted; a second forming roller(8) formed the upper plate or the lower plate passes to interval and is formed so that the second deep part be pressurized; a third forming roller is separately installed the fixed curvature is authorized in upper and lower panel passing through the above-described a first and second forming roller; an elevating mean is descended in the curvature processing; and driving means which is installed in order to rotate this in the state where the above-described first, and 2 forming roller adhere closely in gear.
