摘要： A highly reflective surface coating on a substrate is formed by a coating method in a coating line. A paint is sprayed on the substrate in a viscosity of 18 seconds or lower when measured by means of Ford Cup #4 at 20.degree. C. in a film thickness thicker than a thickness at which the paint sags, the paint containing a solvent or solvents, having a boiling point as high as 110.degree. C. or lower in an amount of 50% by weight or higher.After completion of the spraying, a coat of the paint is dried by a drying step including sequential setting and baking steps. The substrate is held in an ambient temperature during the setting step which is lower than the ambient temperature during the baking step, and the rotation of the substrate in the drying step being carried out about its horizontal axis at a speed which is high enough to rotate the substrate from a vertical position to a horizontal position before the paint coated thereon substantially sags due to gravity yet which is low enough so as to cause no sagging as a result of centrifugal force, thereby allowing the coat formed thereon to achieve a substantially sagless state.This coating method prevents the paint from swelling on an edge portion of the substrate forming a mass, whereby a coat surface is provided with a high degree of flatness.

摘要： A highly reflective surface coating is formed by spraying a paint on a substrate as a vehicle body in a thickness thicker than a thickness at which the paint sags and rotating the substrate about its horizontal axis at a speed between a lower limit and an upper limit in order to cause no sagging until the paint sprayed is cured to a sagless state.Before the paint is sprayed in that thickness, an edge portion of the substrate is lowered than other portions thereof, thus preventing a mass of the paint from swelling on a top coat at its edge portion and providing a good appearance on the surface coating.The lowering of the edge portion thereof is effected by lowering the substrate itself without any coat or by spraying the edge portion in a film thickness thinner than the other portion thereof.The coat sprayed with a paint containing a volatilizable solvent may be dried through sequential setting and baking steps, while a powder paint sprayed may be baked without setting. The paint containing such a solvent may cause sagging in both the setting and baking steps or only in the setting step. The sagging is prevented by rotating the substrate during the time when the paint is sagging.

摘要： In a coating, line a first substrate such as a vehicle body, made of a steel plate, is coated separately from a second substrate made of a different material including a plastic, such as vehicle parts, i.e., bumpers and so on, and the parts are assembled with the vehicle body. The vehicle body and parts are coated separately to form each a highly reflective surface coating. The coating is implemented by a spraying step for spraying the paint on them to form a coat; and a drying step for drying the coat. The paint is sprayed in the spraying step in a film thickness which is thicker than a thickness at which the paint sags on a surface extending at least upwardly and downwardly. And the coat on each of the substrates is dried in the drying step while being rotated about its horizontal axis for a period of time ranging at least from before the paint starts sagging to until the paint achieves a substantially sagless state, rotation of the substrate being carried out at a speed which is high enough to rotate the substrate from a vertical position to a horizontal position before the paint coated thereon substantially sags due to gravity yet which is low enough so as to cause no sagging as a result of centrifugal force.

摘要： The coating method includes the intercoating step for spraying the intercoating paint over a substrate after undercoating, the intercoat drying step for drying the intercoat on the substrate, the overcoating step for spraying the overcoating paint over the dried intercoat on the substrate, and the overcoat drying step for drying the overcoat. In the intercoating step, the intercoating paint is sprayed in such an amount as causing sag, that is, in an amount beyond its sagging threshold value. In the intercoat drying step, the substrate is rotated about its horizontal and longitudinal axis to dry the intercoat.

This method permits the repair of scratched or scraped coating surfaces to produce coating surfaces of high quality without causing fade on the surfaces.

摘要： The coating method contains a spraying step in which a paint is sprayed at least on a coating substrate extending in an upward and downward direction to a film thickness thicker than causing sags of the sprayed paint. The coating substrate on which the paint is sprayed is rotated about the horizontal axis while the sprayed paint is dried until it does not sag any more. The coating apparatus includes a carriage conveying the coating substrate arranged to run along the conveying direction, and the carriage is provided with a supporting base for supporting the coating substrate rotatively about the horizontal axis. One embodiment for rotating the substrate supported by the supporting base is a spring that is disposed on the carriage to rotate the substrate by means of a restoring force produced by the spring. On the passage for conveying the carriage is disposed a force storing mechanism for storing the restoring force in the spring that released the restoring force. Another embodiment therefor is a combination of a chain disposed along the conveying passage for the carriage with a sprocket disposed on the carriage. The sprocket is engageable with the chain and operatively coupled to the coating substrate. By disposing the chain in a fixed manner, on the one hand, the substrate is caused to rotate as the carriage is being conveyed. By dividing the chain, on the other, the substrate is caused to rotate while the conveyance of the carriage is suspended.

摘要： In the coating method containing a coating step for coating a substrate with a paint and a drying step for drying the paint coated thereon, the paint is sprayed on a side extending in an up-and-downward direction and a side extending a horizontal direction in the coating step in such a manner that it is coated in a given film thickness on the horizontally extending side and in a film thickness on the up-and-downwardly extending side, which is thicker than its sagging limit thickness in which it sags. The coating is effected such that the coating on the up-and-downwardly extending side is finished at the same time as or subsequent to the coating on the horizontally extending side.In the drying step, the substrate is rotation about its horizontal axis extending in a horizontal and longitudinal direction of the substrate during a period of time from before the paint sags to until it is cured to a sagless state. The rotation of the substrate is carried out at a speed which is high enough to reverse its vertical position to its horizontal position before the paint sags due to gravity yet which is low enough to cause no sagging as a result of centrifugal force.

摘要： The invention provides methods and apparatus for conducting electrostatic spray coating by which an improved coating layer made uniform in gloss, hardness, weather-tightness, and other characteristics is obtained on an object to be coated. The coating layer is formed with use of a rotary spray head device which is provided with a funnel-like body having an inner wall surface and an open end portion. The rotary spray head device is driven to turn on an axis of rotation surrounded by the inner wall surface of the funnel-like body, and supplied with plural kinds of coating material which are discharged to a substantially common location on the inner wall surface of the funnel-like body simultaneously through respective separate paths so as to form their respective layers superimposed on said inner wall surface of the funnel-like body and move toward said open end portion of the funnel-like body.
