The machine (1) has a coupling unit arranged at an adjusting element i.e. large gear wheel, and controllable by a control device for optionally coupling the adjusting element with a support unit (23) of a shaping unit through an annular through hole (19), so that the adjusting element moves the support unit and the shaping unit along the annular through hole during a rotating movement in order to displace the shaping unit to a desired target operating position. The support unit is fixable at a mounting frame (5) for fixing the operating position.
