Abstract: The invention is related to a method and apparatus for evenly applying an adhesive or protective spray-coating on f.i. sheets of plastic material and/or cardboard in a non-continuous production system. In such system spray-coating by normally stationary spray-nozzles occurs during the forward stroke of the driving unit and three phases of motion can be discerned. In phase I the motion is non-uniform and accelerated, in phase II it is uniform and in phase III it is again non-uniform, but decelerated.In order to achieve uniform spraying in all three phases, in a first embodiment the spray material is applied intermittently during the non-uniform phases. In another embodiment of the invention the spray-nozzles are moved in a direction opposite to that of the sheets to be sprayed.
