In a three-roll rolling mill, for example, an internal gear single-screw drive type, three rolls are arranged in the housing, one of the roll shafts is taken out of the housing, connected to the transmission shaft, and two sets of bevel gears are connected to the shaft. Since it has a structure that drives the other two rolls, the mechanism is more complicated than the two-roll rolling machine, the space inside the housing is narrow, and it is difficult to insert the load cell. It was considered difficult to measure.

ある。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
According to the method disclosed in Japanese Patent No. 4506, a load of a roll of a three-roll rolling mill is applied to a roll having a width equal to or smaller than a width of a roll flange portion between three roll flange portions formed by rolling rolls adjacent to each other. The test flat plate is bitten at the same time and rolled, and a predetermined load cannot be applied to the rolls of the 3-roll mill. Also, JP-A-63-2
In the apparatus disclosed in Japanese Patent No. 38910, a jack cylinder is interposed between rolls via a metal fitting having a surface having the same curvature as the vicinity of the bottom of a roll caliber, and in the case of a two-roll rolling mill, the jack cylinder is interposed. However, it is impossible to apply it to a three-roll mill as it is.
