Claims (1)

[Scope of utility model registration request] In a prefabricated roll in which a large roll is completed by assembling multiple roll segments each having a large portion on a shaft, the roll hole shape contour line within an appropriate length range from the outer circumferential end of adjacent roll segments is the basic hole shape. A part of the outer circumferential end side from the continuous connection point where the roll hole type contour line that is concave from the contour line and has the appropriate length and becomes the basic hole type contour line is at the connection point of the basic hole type contour line. The assembly date is a circular arc whose center is on the radius of curvature line or its extension line or near the radius of curvature line or its extension line.
