ABSTRACT:
A winding device has a drive shaft having a flange, and a holder rotatably mounted on the drive shaft in covering relation to the flange, for winding the web therearound. The holder has a first torque adjustment plate rotatably mounted on the drive shaft and having a surface disposed in facing relation to a surface of the flange, the first torque adjustment plate supporting a plurality of magnets on the surface thereof, and a second torque adjustment plate rotatably mounted on the drive shaft and having a surface disposed in facing relation to an opposite surface of the flange, the second torque adjustment plate supporting a plurality of magnets on the surface thereof. The winding device is capable of winding relatively wide webs having a large thickness ranging from 100 to 150 μm, e.g., photographic photosensitive webs (films), with a low tension fluctuation ratio of ±5% or less, while producing large tension easily and stably. The winding device is constructed for easy maintenance.
