PROBLEM TO BE SOLVED: To freely chuck a roll zapfen of each size by providing a take-up structure connected to a take-up structure of a roll zapfen at the tip of a coupling. SOLUTION: A recessed part 10 is provided in the center to be fitted to an elliptic roll zapfen, and a pair of U-shaped projecting parts 11 are provided on both sides with the recessed part 10 interposed between them to form a coupling 12 of a circular structure when the roll zapfen is fitted. Further, the tip of the coupling 12 is provided with a coupling part of a projecting part connected to a take-up structure of the roll zapfen to integrally connect the roll zapfen and the coupling 12 by a take-up means such as a connecting bolt or the like. Inside the coupling 12, a spacer 13 with a trapezoidal section, which corresponds to a radial length of the coupling 12 and can cope with a change in the grinding rolling roll diameter is inserted to be integrally assembled. |
