Method of and apparatus for disassembling can for measurement of can seam dimensions

An apparatus for disassembling a seamed region of a can, the can including a can body and an end member which are coupled to each other by the can-seamed region, the can body having an end opening closed by the end member and sealing the interior of the can and the end member including a cover hook, said apparatus comprising:

• can holding means for holding the can by gripping the end member and a bottom of the can body;
• rotating means for rotating the can about its own axis which is held by said can holding means;
• and
• a cutter disposed so as to orient a cutting blade of the cutter toward the axis of the can, said cutter cutting the outer circumferential edge region of the end member which externally surrounds a folded portion of the can body in the can-seamed region in a circumferential direction of the can and cutting the can-seamed region such that said cover hook is removable from the end member to permit measuring of the dimensions of the can-seamed region.

An apparatus for disassembling a seamed region of a can so as to permit inspection of the seamed region of the can, the can including a can body and an end member which are coupled to each other by said can-seamed region, the can body having an end opening closed by the end member and sealing the interior of the can and said can-seamed region including a cover hook, said apparatus comprising:

• a can holder holding the can by gripping the end member and a bottom of the can body;
• a rotating device rotating the can about its own axis which is held by said can holder;
• and
• a cutter disposed so as to orient a cutting blade of the cutter toward the axis of the can, said cutter cutting the outer circumferential edge region of the end member which externally surrounds a folded portion of the can body in the can-seamed region in a circumferential direction of the can and cutting the can seamed region such that said cover hook is removable from the end member to permit measuring of the can-seamed region.
