A conveyor means moves spaced treads along a horizontal path defining a pass line where longitudinally spaced spray means are actuated by control means to spray the tapered leading and trailing edges of the treads. An overspray collection means is located adjacent to each spray area to control the overspray. The overspray collection is automated to present a new surface after a predetermined number of sprays to assure an uncontaminated work zone at the site of the overspray.
