PROBLEM TO BE SOLVED: To improve workability of loading or unloading rolls by simplifying a structure supporting the rolls. SOLUTION: In the roll supporter 30, one end of a hollow part of the roll 21 is inserted into a first protrusion 41 and then, the other end of the hollow part of the roll 21 is inserted into the second protrusion 42 to enable supporting of the roll 21 on both the protrusions 41 and 42. One end face of the roll 21 supported on both the protrusions 41 and 42 is made to face the tip face of a regulating protrusion 43 to let them impact each other thereby preventing the slipping of the roll 21 off both the protrusions 41 and 42.
