<p>PROBLEM TO BE SOLVED: To restrain an ink crack when diametrically expanding a stretch label, in a label fitting device.SOLUTION: In a label fitting device, a cylindrical label having elastic extensibility is diametrically expanded by extending by using a plurality of diametrically expansive claws positioned on the label inside, and after inserting a container into the label inside in this state, the diametrically expansive claws are extracted from the label inside, and are thereby fitted to the container by elastic contraction force of the label. The plurality of diametrically expansive claws move to the outside in the radial direction at a first speed up to a first state being an intermediate state where the label is in the middle of reaching a maximum diametrically expansive state, and move to the outside in the radial direction at a second speed slower than the first speed up to a second state being a maximum diametrically expansive state of the label from the first state.</p> |
