ABSTRACT:
A coating or spraying gun is so disposed as to be movable back and forth in a given direction of travel of the member to be coated, including a body of an automotive vehicle, and to reciprocate in a direction different from the direction of travel of the member. The reciprocating stroke of the coating gun is altered depending upon the length of the member in the given direction. By altering the speed at which the coating gun moves back and forth in the direction of travel in accordance with the length of the member in the given direction, a pass pitch of the coating gun can be made constant. A coating region of the member is divided into coating sections or blocks in the given direction, and the sections are coated one after another. In this case, the reciprocating track of the coating gun is altered in accordance the radius of curvature of the sections. This arrangement enables a portion of a complex shape, such as a pillar, to be coated by moving the coating gun along the complex shape of the portion.
