The present invention refers to existing rigidity installed to product stands for maintaining manufacturing method relates to and pipe step inner roller shape, more particularly for the production of stands [...] (Skelp) material to an existing deployment narrower than those of width deployment use of the width to material won plurality of curved loessial embossing drawing and shape of (processed depth to extend according to a width 42) and increases having a line width smaller than the material of work pieces (Skelp) {thickness reducing the increase the curvilinear shapes (t)} the plastic working pressing for planarizing a curved configuration of the material deployment reserve normal condition, and an endoscope being produced increases width, material on one major surface of width deployment in a tight processing roller shape to the surface curvature drawing and embossing roller bending and increases molding loessial rollers shape, bent pressing flat planarizing shape of the first embossing drawing and, renders, in an extended material again contacted with the lower thickness contacted roller at the same thickness for plastic working of material rolled difference 2 through and to improve the durability by reinforcing the width deployment of standard normal yet after its expanded thickness of material of a predetermined height a shaped portion so as to position the roll [...] inner radius which at welded joints, and a and, the pipe (pipe), and shaping the each tube[...] film product form rigidity of existing products impact and normal shaped structure product to retain an archwire within the archwire and saving material and to for maintaining rigid product step inner roller shape relates to pipe and manufacturing method. Such the present invention refers to the thickness of standard width the workpiece having a narrow deployment 15-30% (20) supplying the feature roller reduced draw-, embossing unit (31) forming a 1 13 width developed drawing difference, movable style wrapping material (30) and for, said 1 difference drawing, movable style wrapping material (30) by pressing the molding part planarizing (41) holes along length normal standard 2 to have width deployment of thin film having molding material (40), casting a, said 2 difference molding material (40), a blanket roll compacted at dimmer by supplying a (41) is formed with a regular interval of the inner diameter of is material thickness step (220) at welded joints, and a formed inner radius which is (230) are welded together at circular pipe 8 880000024888 (210) characterized by formed a..
