Abstract: PURPOSE:To decrease scratch on the inner surface and to reduce the variation of wall thickness by making the region equivalent to the reeling part of a plug an inverse hyperboloid of revolution shape and using this plug in combination with a rolling roll. CONSTITUTION:The shape of the region R equivalent to the reeling part of the plug 3A is taken as an inverse hyperboloid of revolution shape.
