- the first pressing member 31, the second pressing member 32, the third pressing member 33, and the fourth pressing member 34 are movable by driving an actuator, for example.
- the thickness of the end portion at the time of completion is determined by the pushing amounts of the first pressing member 31 and the second pressing member 32 . Specifically, it is determined by a block that regulates the pushing amounts of the first pressing member 31 and the second pressing member 32 .
