<p><P>PROBLEM TO BE SOLVED: To allow a fastening roller to move over a position to increase a little the thickness of a seam fastening position when reaching such a position. <P>SOLUTION: A support 5 is combined with a seamer body 1 rotatable between a fastening position to fasten a seam between the fastening roller 3 and a pressing roller 2 and a non-fastening position. The seamer body 1 comprises an operation member 4, at a pre-operation position, which locates the support 5 at the non-fastening position and, at a post-operation position, which locates the support 5 at the fastening position. The operation member 4 and the support 5 are combined to allow the support 5 to turn within a fixed range in such a direction as to enlarge a distance between the pressing roller 2 and the fastening roller 3 in the state of locating the support 5 at the fastening position, and an energizing member 6 which suppressing the turning within the fixed range is provided between the operation member 4 and the support 5. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
