Ukushisa okuphezulu nokucindezela okuphezulu 1:3 isilinganiso sokugeza esiphansi esisindisa amandla umshini wokudaya we-bobbin, lo mshini usezingeni eliphezulu kakhulu, ukonga amandla kakhulu, umshini omusha wokudaya onobungani bemvelo, uphule ngokuphelele indlela yokudaya yendabuko yomshini wokudaya.
Ngaphansi kwesimo sokungashintshi ifomula yokuqala yokudaya, ingavumela umsebenzisi kugesi, amanzi, umusi, izinsiza kanye namahora omuntu ukuze afinyelele uhla oluphelele lokunciphisa, futhi angakwazi ukuqeda umbala futhi anciphise kakhulu umehluko we-cylinder.
