Abstract
The present invention discloses a sheet winding structure to reduce indentation transfer occurring because of sheet thickness or adhesive colloidality of the innermost layer of the sheet. The sheet winding structure comprises: a winding core having an outer surface, wherein the outer surface of the winding core comprises a recess thereon; and a sheet winded over the outer surface of the winding core, wherein a beginning portion of the sheet is disposed in the recess.
Claims31
A sheet winding structure, comprising:
- a winding core having an outer surface, wherein the outer surface of the winding core comprises a recess thereon;
- and
- a sheet winded over the outer surface of the winding core, wherein a beginning portion of the sheet is disposed in the recess.
A winding core used for winding a sheet, comprising:
- a core body;
