Abstract
The separator production method in accordance with an embodiment of the present invention includes a coated article winding off step of winding off, from a core, a separator original sheet which has been taken up in a coated article taking up step of winding the separator original sheet on an outer peripheral surface of the core while oscillating the core in a rotation axis direction, and the core is oscillated in the rotation axis direction in the coated article winding off step.
Claims7
A method for producing a film, said method comprising the steps of:
- taking up a film by winding the film on an outer peripheral surface of a core while oscillating the core in a rotation axis direction;
- and
- winding off the film, which has been taken up in the taking up step, from the core,
- in the winding off step, the core being oscillated in the rotation axis direction.
A method for winding off a film wherein a film, which has been taken up so as to be wound on an outer peripheral surface of a core while the core is being oscillated in a rotation axis direction, is wound off while the core is being oscillated in the rotation axis direction.
