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.

Abstract: A plurality of rotatable attracting units are mounted on a rotary member each for attracting the bottom of one of the can barrels supplied from a supply path in a first position. Each attracting unit is inactivatable to release the one can barrel onto a conveyor path in a second position after the one can barrel has been rotated by the rotary member through a prescribed angle from the first position to the second position. A holder is disposed in the first position for holding the can barrels, one at a time, supplied from the supply path while centrally aligning the bottom of the can barrel with the center of rotation of the attracting unit in the first position. The attracting unit is stopped by a retarder against rotation about its own axis when the attracting unit is moved into the first position and attracts the can barrel held by the holder.

Abstract: A barrel and a cover, to be combined into a container, are rotated by a preliminary machining feeder while they are supported by a first rotatable seaming chuck and a first holder. During rotation of the preliminary machining feeder, a flange of the barrel and an end hook of the cover are pressed by a first seaming segment against the first seaming chuck, so that the barrel and the cover are preliminarily fastened and necked in. The barrel and the cover are then transferred by a transfer unit to a final machining feeder on which the barrel and the cover are supported by a second rotatable seaming chuck and a second holder. The final machining feeder is rotated to feed the barrel and the cover while they are finally fastened and necked in by a second seaming segment. The first and second seaming segments are arcuate in shape and have their inner shaping surfaces progressively approaching the preliminary and final machining feeders, respectively, in the direction of rotation thereof.
