The machine has an actuator that is operatively connected with a program-equipped control unit. The control unit is provided to control actuator to cause displacement of an object point to back and forth between two different positions relative to a discharge opening. A level and mass flow rate detection unit is provided to detect whether containers (8,9) are emptied when control unit receives an appropriate command entered into a control module, such that a metering orifice is opened to minimize mass flow of to-be-spread material.
