ABSTRACT:
A thin material winding apparatus includes: a winding shaft for winding up a strip of thin material; a drive motor for driving the winding shaft; and a control unit for controlling the drive motor in such a way that the product of a diameter of a rolled thin material on the winding shaft and a tension exerting on the thin material is constant during a specified winding period. The control unit is provided with a diameter detecting device for detecting a diameter of the rolled thin material; a memory for storing a relationship between a target tension and a diameter of the rolled thin material to make the product of a diameter of the rolled thin material and a tension on the thin material constant; a target tension readout device for reading out a target tension in accordance with a detection of the diameter detecting device; and a drive motor control portion for controlling the drive motor so that the thin material has a tension agreeing with the target tension.
