Claims

[Scope of Claim for Utility Model Registration] (1) The diameter gradually expands from the end of one small diameter part to a large diameter part, and a suddenly enlarged step is formed as a hump in the middle, and then it gradually expands to the other large diameter part. In the Atsel Mill elongator roll having an outer shape extending to the end, the hump position is formed at a position moved by a certain distance c from the standard hump position of the standard elongator roll having standard dimensions to the small diameter end side, The end of the small diameter part is formed to extend outward from the end of the standard small diameter part of the standard elongator roll by the same dimension as the constant dimension c, and the dimension c is the distance from the standard hump position to the end of the standard small diameter part. Atsel Mill's elongator roll is characterized by being smaller than its dimensions. (2) An Atsel mill with an external shape that gradually expands to a larger diameter from one small diameter end, forms a step that suddenly expands as a hump, and then gradually expands to the other large diameter end. In the elongator roll, the large-diameter end is formed to extend outward by a certain dimension d from the standard large-diameter end of the standard elongator roll having standard dimensions, and the dimension d is the standard elongator roll. Atsel Mill's elongator roll is characterized by being smaller than the dimension from the standard hump position to the standard large diameter end.
