The member for retaining and for regulating the flow rate of material comprises a bell for closing off a discharge opening, and a central metering body which is oblong and distinctly more slender than the bell. The bell and the central metering body can be moved relative to one another so that the distance which separates the two of them can be freely adjusted.
