Automatic and reproducible spraying of liquid materials on complex tool surfaces is attained through a multinozzle spraying block, traversed by supply passages for the spray material and the air for spraying, and comprising, on at least one of its faces, a series of valves provided with elastic obturating membranes and with pneumatic logic control, programming and communication of the spray material supply passages with the spray air outlets of the nozzles grouped on at least one of the block faces. Application of the multinozzle spraying block to automatic treatment is achieved by spraying materials on tool surfaces under constant conditions on repetitive-cycle machines. |
