TITLE: A DEVICE FOR MAKING A THREE-DIMENSIONAL MARKER IN THE FORM OF A FOAM BODY A device for making a three-dimensional marker intended as a temporary traffic marker, for example, on road surfaces etc., said marker consisting of a foam body having a stable shape during a predetermined period and adhering to the road surface. The foam body preferably consists of an air-mechanically worked foam of air, water and a foam-forming concentrate. The device for making such a marker comprises a container under pressure for a premixed liquid foamforming preparation, a foam generator connected to said container for mechanical working of the foam-forming preparation with the aid of air into foam, and a discharge unit connected to the foam generator via a tube and determining the final size and shape of the foam body. Units are operatively connected to each other via control units. |
