필름 롤(R)의 제조 시스템(1)은 널링 가공기(6)와, 권취기(7)를 구비한다. 널링 가공기(6)는 폭 방향(TD)에 있어서 필름(F)의 단부에 널(K1, K2)을 형성한다. 권취기(7)는 널(K1, K2)이 형성된 필름(F)을 권취하고, 필름 롤(R)을 제조한다. 널(K1, K2)은 폭 방향(TD)으로 진폭하면서 흐름 방향(MD)으로 연장되는 파형상을 갖는다. 권취기(7)는 필름 롤(R)에 대하여 폭 방향(TD)에 있어서의 널(K1, K2)의 위치가 일치되도록 필름(F)을 권취한다. 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.
