surface 5 which is to be marked such as a road surface is connected downstream from the storage container 12 the material outlet 2 is fastened to the bottom side of the frame 10 and is at a predeterminable distance above the surface 5 in cross direction of the device 1 that is viewed vertically to the drawing plane of fig1 the material outlet 2 consists of a number of separate outlet openings which are arranged next to one another and which cannot be seen individually herein a rotational body 3 which can be set into rotation and the outer periphery of which is provided with structural elements is arranged below the material outlet 2 during operation of the device 1 the latter moves across the surface 5 which is to be provided with a marking in the direction of movement 14 which is illustrated by means of the arrow the conveying device 13 thereby conveys a predeterminable dosage of marking material from the storage container 12 to the material outlet 20 and to the individual outlet openings thereof through which the marking material initially falls down freely in the form of a plurality of parallel material flows and then hits the rotational body 3 which is set into rotation after covering a short distance the material flows of the marking material which hit the rotational body 3 are divided into irregular and uneven material portions and are conveyed to the surface 5 which is provided with a marking by means of the structural elements attached thereto glass beads can be removed from a further storage container 17 which is arranged in the rear part of the device.
