<p>PURPOSE:To provide a sampling method which is capable of identifying by which seaming head a sampled can has been seamed without stopping a can manufacturing line, and capable of achieving correct identification without changing the correspondence relation between the sampled can and the seaming head even when the can manufacturing line is temporarily stopped. CONSTITUTION:The angle of rotation of a seamer 4 after a seaming head detecting sensor 21 detects a body 20 to be detected by a seaming head until a can detecting sensor 22 detects the first can, is detected by means of a rotational angle detecting sensor 24, and the seaming head where the first can enters is detected on the basis of this detected angle and the rotational angle corresponding to the arrangement pitch of the seaming pitch.</p> |
