1. A device for applying a bead of material, comprising
a flexible nozzle body which defines a flow-through volume through which a material for the bead of material can flow and which is partially delimited by a walling formed by the nozzle body, having a feed opening for feeding the material into the flow-through volume, the nozzle body defining a mouth region through which the material can exit the volume,
an actuator system which is arranged on the nozzle body and which is set up to change a cross section of the mouth region while deforming the nozzle body,
the walling forming a barrier between the flow-through volume and the actuator system,
wherein the flow-through volume is designed as a half-open volume which is open at a bottom and in the mouth region and which is delimited at a top and on two opposite sides by the walling formed by the nozzle body.
