Abstract
A coating nozzle (3) movable in a horizontal direction perpendicular to an advancing direction of a vehicle body (1) drops or trickles a strippable paint linearly along one side of the periphery of an area to be protected, and an air blow-off unit (4) blows off air (F) at a predetermined angle against a surface to which the strippable paint is applied, whereby the strippable paint is spread over the area to be protected, and when the thus spread strippable paint becomes dry, it forms a protective film. The strippable paint is prevented from adhering to a portion other than the area to be protected, and the protective film of strippable paint has a uniform thickness.
Claims17
A method of forming a protective film on a coated surface of a completed automobile body for temporarily protecting the coated surface, comprising the steps of:
- a) applying a strippable paint onto the coated surface linearly along one side of a periphery of an area of the coated surface to be protected;
- and
- b) blowing air from above obliquely against the coated surface to which said strippable paint has been applied, for spreading said strippable paint over the area of the coated surface to be protected;
- and
- c) drying said spread strippable paint.
An apparatus for forming a protective film on a coated surface of a completed automobile body for temporarily protecting the coated surface, comprising:
- a) a coating nozzle reciprocally movable in a horizontal plane for applying a strippable paint onto the coated surface of the automobile body;
- b) an air blow-off unit for blowing air obliquely against the coated surface of the automobile body for spreading said strippable paint which has been applied to the coated surface, in a direction substantially normal to the direction of reciprocal movement of said coating nozzle;
- c) a horizontally movable frame structure carrying thereon said coating nozzle and said air blow-off unit and reciprocally movable in a horizontal plane in a direction normal to said direction of reciprocal movement of said coating nozzle;
- and
- d) a vertically movable frame structure carrying thereon said horizontally movable frame structure and reciprocally movable in a vertical direction.
