る。According to the present invention, in the elastic support member that presses the strip material against the rotary shear blade during shearing, the elastic coefficient of the surface elastic portion is higher than that of the inner elastic portion that presses the surface elastic portion. Since it is set to a large value, the elastic deformation of the inner layer elastic part can absorb the elastic deformation of the surface elastic part when pressing the strip material of any thickness, so that the surface elastic part is almost elastically deformed. It is possible to press without causing the force, and it is possible to perform shearing while showing a uniform pressing force against each rotary shearing blade. Further, therefore, the shearing band material can be neatly sheared without being attached with a cutter mark or the like, without impairing the commercial value.
