摘要: The applicator device for multicomponent plastics, in particular polyurethane, onto a continuous cover layer, preferably double belt system, has portal which extends over the layer and transversely to direction of movement. A mixing head (11) having at least two discharge nozzles (12 14) can be moved back forth on portal. When lifetime one nozzle expired due encrustation with reaction mixture, next comes into use without interruption operation (zero overlap). This ensures that production process does not have interrupted long period, example shift, an even, uniform product is produced entire time. It possible principle order switch move relative or vice versa head.
