Known devices consist of a vehicle comprising a paint container which has a control unit to dispense the rate of paint flow. The vehicle is either pulled by a tensioned cord or pushed by a pulling device for very long lines, whereby the paint flow is started or stopped at premarked points. The use of such devices is labour-intensive and very imprecise. The device according to the invention is characterized by a vehicle having its own drive being automatically guided along a line provided by a laser beam, and a marking device applying marks to the floor surface in accordance with a preset marking program depending on the path travelled. The device is particularly suited for marking trade fair halls, car parks and sports facilities.de608006621patent1990-4013950
