1. Umshini ungaqhuba ukubhebhetheka phambili phambili nokubuyisela emuva imali ekhokhwayo, futhi ungaqhuba inqubo yamafutha ne-wax ngedivayisi yokufudumeza ye-roller
2. Ama-rollers amathathu ahlukene anama-roller okuzenzakalelayo we-roller-kalula ukuze ashintshe
I-3. Isithwali se-blade silawulwa yidivaysi ye-pneumatic, ukuthuthukela ngokuzenzakalelayo nokubuyela emuva. Ingcindezi phakathi kwe-blade ne-roller iyashintshwa. Futhi idivaysi yokuphindisela ye-axial ethomathi-athomathikhi ifakwe umthwali we-blade ngokubuyisela okuguqukayo imvamisa. Lokhu kuthuthukisa ngokumangazayo umphumela.
I-4 Kuyamangaza ngokumangazayo indawo ukuze ithuthukise ikhwalithi ye-coating.
