PURPOSE:When winding a film while holding a flanged core by a stopper board, to prevent the mis-winding by providing a projection for pressing the circumferential section around the central hole of a flange board on the stopper board and constructing such that it is wound while enlarging the flange board interval at the outer-circumference of the core body. CONSTITUTION:When winding a film, a core body 1 is inserted between a pair of stopper boards 3 to advance the stopper board 3 such that they will approach each other thus to project the central projection 31 into the central hole 13. Consequently the circumferential section of the central hole 13 is pressed by a tapered face 32. Consequently the flange board 12 deformed as shown by the dashed line will be enlarged as shown by the solid line to correct the interval of the flange board 12. In such a manner when winding the deformed flange board 12 while correcting the interval, the mis-winding and the mis-rewinding can be prevented. |
