Abstract
A wagon (90b) includes a plurality of horizontal support bars (91f). A separator roll (12b) is stocked while the horizontal support bar is inserted into a core of the separator roll (12b) around which core a separator is rolled. This can prevent deformation and roll misalignment of the stocked separator roll.
