Depi se plis travay ou fè nan chak "estasyon" nan mouri a, li enpòtan pou teren an dwe avanse trè jisteman konsa ke li sarmoniz ki nan yon milyèm kèk nan yon pous pandan l ap deplase soti nan estasyon yo nan estasyon. Bal ki gen fòm oswa konik "pilòt" antre deja pèse twou wonn nan teren an asire aliyman sa a depi mekanis a manje anjeneral pa ka bay presizyon ki nesesè nan longè manje.

Since additional work is done in each “station” of the die, it is important that the strip be advanced very precisely so that it aligns within a few thousandths of an inch as it moves from station to station. Bullet shaped or conical “pilots” enter previously pierced round holes in the strip to assure this alignment since the feeding mechanism usually cannot provide the necessary precision in feed length.
