A method of coating a rotating object to be coated. In rotating coating a plurality of objects to be coated with a spray gun, each spray coating is carried out in a state of being mounted on a support that rotates left and right in both directions, thereby Carry out overall painting. In the past, a spray gun was used to spray continuously, and the object to be coated was sprayed over the entire range while it was passing through. However, it was found that when the object to be coated rotated (moved) in a direction away from the spray gun, the coating effect was hardly obtained. Therefore, the present invention only sprays when it is placed on the rotating support and comes towards the spray gun, so it can greatly reduce the consumption of paint and improve the painting efficiency.
