PURPOSE: To securely and appropriately bundle a cylindrical sheet by mounting a pair of bundling guides for bundling the cylindrical sheet formed in a thin and long shape onto a pair of sliders which move oppositely to each other.

CONSTITUTION: A cylindrical sheet 5 is formed into a thin and long shape with a pair of narrowing arms 44, 44 rotating to approach each other. A pair of bundling guides 47, 48 for bundling the cylindrical sheet 5 formed in a thin and long shape are mounted on a pair of sliders 34, 35 which move oppositely to each other. Thus even if a diameter of the cylindrical sheet 5 is relatively large, the pair of sliders 34, 35 move to approach each other so that the pair of bundling guides 47, 48 can bundle the cylindrical sheet 5 of a thin and long shape into a small bundle. Therefore such trouble does not occur that the cylindrical sheet may not be properly bundled to kinder the following operation.
