ABSTRACT:
A setup method for preventing a “two-leaf cutting” by only operating a machine without using fingers in cutting an end of a strip blade material having an enclosed rectangular geometry. The steps include: the strip blade material being once advanced to a position, where “two-leaf cutting” will not occur; then a cutting tool being lowered; a cutting tool tip of a cutting tool component being lowered to a level of the same as or under that of a top edge of the strip blade material; then the strip blade material being retracted; and finally, the strip blade material being retracted by the same amount as that of the advance from the desired position.
