<p>Machine to spray paints and the like onto objects moving on a belt conveyor (T), comprising a plurality of spray guns (3) movable at variable speed along a circular path lying on a plane parallel to the surface of the conveyor, and having at least two sections substantially transversal to the moving forward direction of the conveyor. The spray guns (3) are all carried by a single support (2) mounted at the end of a rotary arm (1), to which there are associated means (5 to 8) to keep the angular position of said support (2), during its rotary movement, unvaried in respect of the moving forward direction of the conveyor (T). The variable speed motion is imparted on the support (2) for the spray guns (3) by drive means (11 to 15), with a substantially sinusoidal law, so as to cause said guns (3) to travel at maximum speed in correspondence of the path sections where they are inactive. <IMAGE></p> |
