ABSTRACT:
A packed can is seamed by clamping a can body and a lid between a lifter and a chuck, rotationally driving the entire assembly while applying a compression force thereto, and pressing a groove portion of a roll from the outside to an edge portion of the lid to deform such edge portion. Seaming is effected by pressing the groove portion of the roll to the edge portion of the lid with the rotary axis of the roll maintained inclined with respect to the rotary axis of the chuck.
