Abstract: The rate of travel of each spray head (27) (27A) of a rotary sprayer along arcuate paths across a conveyor (16) carrying work to be spray-coated is so varied from a maximum adjacent the margins of the conveyor (16) to a minimum centrally thereof that the thickness of the deposited layer is substantially uniform wherever applied. In one embodiment, each spray head (27) has a connection (26) (92) (93) (94) with the outer end of a fixed rotor arm (25). A rod (95) pivotally attached to the connection (26) has a cam follower (99) in engagement with a rotor-encircling cam path (100) and a link (97) pivotally connected to the rotor hub (23) with the cam path (100) operable to effect the swinging of the spray heads (27) to affect their travel rates in the wanted manner. In another embodiment, each spray head (27A) is fixed on a rotor arm (26A) pivotally connected to the rotor hub (23A) and having an angularly disposed arm (105) carrying a cam follower (99A) held in a rotor-encircling cam path (100A) operable to swing the rotor arms (26A) to affect the required variations in the rates of travel of the spray heads (26A). To prevent momentary pressure increases and decreases as spray head valve elements (38) are closed and opened from being causes of uneven sprayed coats, the rotor (20B) has a chamber (110) through which spray material is delivered which is disposed and dimensioned to provide an air cushion.
