[Prior Art] Rolls are used for rolling in various rolling equipments, but when the operating temperature of the rolls is different from room temperature, deviation of thermal expansion or contraction, that is, distortion causes the roundness of the rolls to change,
Bending occurs in the axial direction of the roll within elastic deformation, and this bending appears as "run-out" when the roll is rotated. For example, in a calendar, when the rolling operation is performed in a state where the above-mentioned “runout” occurs on the calendar roll, as shown in FIG. 5, unevenness occurs in the longitudinal direction of the rolled sheet a,
Not only is the thickness accuracy reduced, but the product that can actually be used is the range indicated by the minimum thickness b, so the yield is reduced. Further, in addition to such thickness accuracy, uniformity accuracy of patterns, color patterns and the like is also impaired.

そこで従来、前記の歪を防止する方法として、軸体の

とかの方法が考えられた。
Therefore, conventionally, as a method of preventing the above-mentioned distortion, a method of making the material of the shaft body completely uniform, or processing at the operating temperature state has been considered.

[Problems to be Solved by the Invention] However, for example, when the operating temperature is high (about 180 to 220 ° C. in a polyvinyl chloride calender), the method of heating the shaft, the temperature retention, and the uniformity (temperature It is difficult to put into practical use due to problems such as unevenness), handleability, safety and the degree of thermal influence on the processing machine. Generally, the processing accuracy is used at room temperature, or the processing is performed at the operating temperature. Since it was used as it was, the surface roughness was rougher than that processed at room temperature, and when buffing was performed, roll accuracy deteriorated, and product quality and yield still remained a problem.
