An axial drive for moving the upper stopper (7) on a turning arm (29) into and out of the pipe section (4) is provided. A pivot drive serves to move the upper stopper (7) into a parking position away from the axis (9) of the pipe section (4) and into a stand-by position in the axis (9) of the pipe section. A vertical drive for the lower stopper (8) is provided. A driven swivel wiper (32) serves to remove a tablet of coffee grounds. The upper stopper (7) is solidly attached to the turning arm (29). a single motor (10) with a following power divider (16) is provided for the axial drive and for the pivot drive of the turning arm (29) with the upper stopper (7) as well as the drive of the swivel wiper (32). The power divider (16) has a stroke-like driven pivot column (15), an axially secured guide bushing (17), and a stationary grooved bushing (18). The guide bushing (17) and the grooved bushing (18) each have a guiding slot (27, 23) for a crosshead (28), which is connected to the pivot column (15).
