A device for applying free-flowing material to a movable substrate (1), especially for intermittent application of liquid adhesive. At least one supply channel (46) feeds free-flowing material and at least one nozzle unit (8) with at least one output channel is connected with the supply channel (46) and ends in an output orifice for delivering material. A valve mechanism interrupts the flow of material and includes a movable valve body (14) and a valve seat (44). The valve body (14) interacts with the valve seat (44) in such a way that the flow of material is interrupted by movement of the valve body (14) to a closed position and released by movement into an open position. The valve body (14) comes into contact with the valve seat (44) to interrupt the flow of material through a movement contrary to the direction of flow of the material.
