Abstract
A winding apparatus configured to wind a sheet material is provided. The apparatus includes a belt configured to contact an outermost circumferential surface of a rolled material to rotate the rolled material, and a belt driving device configured to rotationally drive the belt. The apparatus is configured such that a radius of curvature of a portion of the belt configured to be in contact with the rolled material increases in conjunction with an increase in a diameter of the rolled material. The rolled material is the sheet material wound to form layers in its thickness direction. The sheet material is a flexible sheet-shaped member.
