Spaced apart, hollow, can bodies are formed around a stubhorn and moved past a spray nozzle for spray coating the inside seams of the can bodies. Each can body is received from a conveyor and moved past the spray nozzle at a sufficiently reduced speed to allow the succeeding can body to move into contact with the preceding can body. The spray nozzle continuously sprays the seams of the can bodies, which form in effect a continuous "tube" of can bodies moving past the nozzle. Each can body is conveyed away from the coating station at a speed preferably corresponding to the input conveyor speed so that the spacing between the can bodies is restored. Conveying apparatus at the coating station is provided with a one-way clutch to accommodate conveyor overrunning when uncoated cans are received and when coated cans are drawn away.
