wherein the partition has a shape of a sheet.
3. The roll device according to claim 1 ,
wherein the leading end of the partition is inserted between the outermost layer and the inner layer of the web in a direction counter to a winding direction in which the winding roll winds the web fed from the feeding roll.
4. The roll device according to claim 1 ,
wherein the partition is flexible.
5. The roll device according to claim 1 ,
wherein a coefficient of static friction between the partition and the web is smaller than a coefficient of static friction between the outermost layer and the inner layer of the web.
