FIELD: manufacturing technology.
SUBSTANCE: invention relates to automated system (PA) for application of undercoat when making hinged parts for vehicles, as well as to a method for controlled application of ground fluids on surface of suspended components and use of polymer-cellulose nonwoven materials reinforced with high-pressure water jets. Automated system (PA) for application of undercoat when making hinged parts for vehicles comprises at least one dispensing coil (02), one receiving coil (03), one head (08) for application of coating with nozzle opening and polymer-cellulose non-woven material (19) reinforced with water jets of high pressure. Polymer-cellulose non-woven material (19), hardened by high-pressure water jets, passes from transfer coil (02) over head (08) for application of coating to receiving coil (03). This polymer-cellulose non-woven material (19) is located before nozzle opening (20). Through the nozzle opening, it is possible to supply ground coat so that the primer liquid can be applied to the surface of the structural element through the polymer-cellulose non-woven material (19). Method for controlled application of primer liquids on the surface of suspended components for vehicles using an automated system (PA) for applying of undercoat includes at least preparation of a hinged part and installation of head (08) for applying a coating with impregnated polymer-cellulose non-woven material (19), reinforced by high-pressure water jets, on surface of structural element. Method also includes moving surface of structural element or head (08) for applying coating along contours coated with ground liquid, and disconnection of contact between head (08) for application of coating with impregnated polymer-cellulose non-woven material (19), strengthened water jets of high pressure, and surface of structural element. Priming fluid is supplied through nozzle opening in head (08) for application of coating. In the method, surfaces of structural elements are glass, ceramic or plastic surfaces.
EFFECT: reduced consumption of material and prevention of formation of gaps in the primer, or primer treads, or priming buildup.
