<p>Disclosed is a device for expelling drops of flowable substances, wherein a perforated rotating drum (60) is provided and a nozzle strip (50) with a groove-shaped recess (12) for internally supplied subtances is associated with the lower region thereof which is associated with a belt (7) which is guided underneath the drum on the side thereof which faces the inner periphery of the drum. A retainer strip (13') is disposed at least in said groove-shaped recess area (12) of the nozzle strip (50,50a) extending in a perpendicular manner with respect to the direction of flow. Said retainer strip forms a through-flow slot (15) together with a wall (12a) of the recess (12) for dosing the substance to be expelled in drop form and for stablizing the flow upstream from the exit area.</p> |
