The invention relates to a method and device for applying a material pattern by means of a sequentially operating applica- tor (14) to a substrate (18) moving relative to said applicator (14), by way of a control valve for liquid material, in particular a hot melt, said valve being controllable for opening and closing, which material pattern in the direction of movement is sub-divided into pattern parts with slight spacing between them, and there being at leas t two control valves (24, 26) connected to the material supply, and the respective valves being made to open and close sequentially. A considerably faster operation is achieved in this way.
