ABSTRACT:
A plurality of sets of sheet drive rollers including a touch roller for urging a sheet against a core are provided on a running path, along which a sheet is supplied to a core in a shaft drive type winding unit. Two adjacent ones of said sets of sheet drive rollers are coupled to each other by a fine speed adjustment interlock mechanism. The speed change ratio of the fine speed adjustment interlock mechanism is adjusted to remove or reduce the variation in the tension in the sheet between the two rollers and also control the tension to a level suited for the winding.
