Abstract

Can barrels of uniform diameter produced from a can barrel forming device by forming a square-shaped blank into a tubular shape with opposite edges joined linearly, are conveyed successively coaxially in spaced relation at a first speed with the joined areas of the can barrels directed upwardly. Then the can barrels are conveyed at a second speed slower than the first speed such that the open edges of the can barrels are coaxially spaced closely with small gaps left therebetween. Paint is continuously applied to the inner and outer surfaces of the joined areas while the can barrels are being conveyed at the second speed with the open edges of the can barrels being closely spaced by the small gaps.
