PURPOSE:To secure such a roll of a sheetlike work that is stable in the desired hardness, by detecting the ratio of an actual value to an apparent value in winding, while the sheet work while adding a proper extent of compensation to winding tension, surface pressure and/or both in a direction where the value is congruous with the preset value. CONSTITUTION:A value M1 proportionate to a winding apparent value is calculated from a winding core diameter D0 out of a winding core diametral data setter (b) and a winding diameter D out of a winding diametral operational part (a) at an apparent value operational part (c), while a value M0 proportionate to an actual value in winding is calculated by a winding actual value operational part (e) from an output pulse PL of a measuring instrument PGL and thickness data S out of a data setter (d). Next, from these values M1 and M0 the ratio AD of the apparent value to a substantial value in winding is calculated by an AD operational part (f). A desired AD value SAD corresponding to the winding diameter is compared with the ratio AD, and the deviation signal DELTAAD is inputted into a compensation signal generating part (h), and according to the data S and the signal >=AD, a compensation signal is generated at a proper extent in a direction where both values AD and SAD are congrous with each other.
