Kuna kilekottide lõikamiseks mõeldud kuum nuga kuumutatakse elektromagnetismi toimel, suletakse kilekotid ka tooraine lõikamisel. Söötmiseks kasutatakse samm-mootorit. Iga kord, kui kuum nuga tõstetakse hetkeni, mil kuum nuga kukub, söötmispikkus on toodetud pooltoodete kilekottide pikkus.
Peamootori ja samm-mootori vaheline koordineerimine on väga oluline, sest samm-mootor suudab materjale ette anda ainult siis, kui kuum nuga on kukkumiseks tõstetud.
