It is necessary to determine the length and the length of the lead wire that protrudes a little from the surface of the upper punch 5, but in order to determine the height at which the upper punch 5 pulls out the lead wire 7, the roll cam 31 must be adjusted. The height adjustment for cutting the lead wire 7 is performed using the cutter body 12, that is, the fixed blade 13.
and the height of the rotary blade 14 is adjusted.
