Summary: | This system 1 for producing a film roll R is provided with a knurling machine 6 and a winding machine 7. The knurling machine 6 forms knurls K1, K2 on the ends of a film F in the width direction TD. The winding machine 7 winds the film F having the knurls K1, K2 formed therein and produces a film roll R. The knurls K1, K2 have a wavy shape that extends in a flow direction MD while undulating in the width direction TD. The winding machine 7 winds the film F so that the positions of the knurls K1, K2 match in the width direction TD with respect to the film roll R. |
