Abstract: A hollow drum is rotatable about a horizontal axis and includes openings around its circumference for discharging drops of a free-flowing substance onto a cooling belt in the manufacture of pastilles. A stationary body disposed inside the drum is spaced from the interior surface of a front side of the drum to form therewith a sickle-shaped gap leading to the drop-forming zone. A channeling member rests against an external surface of the front side of the drum to form therewith an upwardly open channel. The supply passage which delivers the freely flowable substance to the drum can be defined by the channel, whereby the substance would be fed into the upwardly open end thereof and would flow into the gap through the drum openings. Alternatively, the supply passage could be defined by a space within the stationary body which communicates with the gap at a location disposed above the drop-forming zone.
