<p>A winding device has a drive shaft (104) having a flange (102), and a holder (106) rotatably mounted on the drive shaft (104) in covering relation to the flange (102), for winding the web (30) therearound. The holder (106) has a first torque adjustment plate (110) rotatably mounted on the drive shaft (104) and having a surface disposed in facing relation to a surface of the flange (102), the first torque adjustment plate (110) supporting a plurality of magnets (120) on the surface thereof, and a second torque adjustment plate (114) rotatably mounted on the drive shaft (104) and having a surface disposed in facing relation to an opposite surface of the flange (102), the second torque adjustment plate (114) supporting a plurality of magnets (122) on the surface thereof. The winding device is capable of winding relatively wide webs having a large thickness ranging from 100 to 150 mu m, 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. <IMAGE></p> |
