A device to apply liquid adhesive, especially hot-melt adhesive, to a length of material with the adhesive being interrupted includes an application head which has a control element with a pass-through channel and a rotatingly drivable control slide. The pass-through channel is connected to a supply channel for molten hot-melt adhesive at its entry end and to a nozzle aperture for the molten adhesive at its exit end. The control slide, in the course of a 360 degree rotation, opens and closes the pass-through channel at least once.
