PURPOSE:To contrive the improvement in the accuracy of spraying thickness by holding a spraying distance at a predetermined value, and controlling the moving speed of a nozzle and an amount of ejection. CONSTITUTION:A traction truck 1 is intermittently moved pitch by pitch along the direction X, a reference locus in line with a wall surface 3 to be spray coated is drawn every pitch by a sprayer nozzle 17, and said sprayer nozzle 17 is shifted along the direction Y. Hereon, on the basis of the moving locus of the nozzle in parallel with a moving locus, the before or behind flutuation in a spraying distance corresponding to another wall surface 3 to be spray coated being shifted by one pitch is detected by a detector 8 and memorized in a computer. In executing the next spraying operation, the reference locus for the one- pitch preceding step is corrected on the basis of said data to hold the spraying distance constant at all time. |
