Abstract
In a winding method of a sheet member for winding a sheet member having an inclined side portion 7a inclined with respect to a longitudinal direction at least on one side in the longitudinal direction around a winding cylinder 50 in more than one turn from a tip end of the inclined side portion 7a as a winding start tip, winding of the sheet member is started in a small-diameter portion 51a of the winding cylinder 50 to which a radial difference is given by providing a step 54 to make a diameter smaller on one side in an axial direction and larger on the other side in the axial direction.
Claims9
A winding method of a sheet member for winding a sheet member having an inclined side portion inclined with respect to a longitudinal direction at least on one side in the longitudinal direction around a winding cylinder in more than one turn from a tip end of the inclined side portion as a winding start tip,
- wherein winding of the sheet member comprises winding the sheet member starting in a small-diameter portion of the winding cylinder to a larger-diameter portion of the winding cylinder between which a radial difference is given by providing a step to make a diameter smaller on one axial edge side of the winding cylinder and a diameter larger on the opposing axial edge of the winding cylinder side,
- the sheet member is placed on a table before winding starts, when the sheet member is placed on the table, a longitudinal direction of the sheet member and a longitudinal direction of the table coincides with each other, and
- the winding cylinder moves in the longitudinal direction of the table by rotating, thereby the sheet member is wound.
