Each roller has regions of reduced diameter between adjacent discs, and the first and the second roller are located so that the axial location of the spaced discs on the first roller coincides with the regions of reduced diameter between adjacent discs on the second roller. A roller suitable for use in the roller assembly and a dispenser including such an assembly are also provided.
