The rigid support ring has a cylindrical internally toothed support surface. A radially flexible uncoiling bush has a toothed outer casing surface. A drive arrangement joined to the drive shaft, keeps, by means of at least partly elastic arms or plungers (40), one or more first peripheral sections of the outer casing surface engaging with the support ring's support surface. The arms or plungers are integrated with an annular band. |
