Imiqulu eshisayo,imiqulu yomsebenzifuthiimiqulu yokusekelayoziyizingxenye ezibalulekile ezinqubweni ezihlukahlukene zezimboni futhi zidlala indima ebalulekile ekukhiqizeni izinto ezihlukahlukene. Lawa ma-roller asetshenziswa ezimbonini ezifana nensimbi, i-aluminium nephepha futhi aklanyelwe ukumelana namazinga okushisa aphezulu kanye nemithwalo esindayo. Ukuqonda ukubaluleka kwala ma-roller kanye nemisebenzi yawo kubalulekile ekuqinisekiseni inqubo yokukhiqiza ephumelelayo nephumelelayo.

Amaroli ashisayo, abuye abizwe ngokuthi ama-work rolls, asetshenziswa ezigayweni ezishisayo ukuze alolonge futhi aguqule izinto zensimbi emazingeni okushisa aphezulu. Lawa ma-roller aklanyelwe ukumelana nokushisa okuphezulu kakhulu nokucindezela, okuwenza abaluleke kakhulu ekukhiqizeni insimbi neminye imikhiqizo yensimbi. Izinga nokuqina kwama-hot rolls kuthinta ngqo ikhwalithi yomkhiqizo wokugcina, okwenza kube yingxenye ebalulekile enqubweni yokukhiqiza.

Ngakolunye uhlangothi, i-roller yokusekela idlala indima ebalulekile ekunikezeni ukuzinza nokusekelwa kwe-roller yokushisa. Lawa ma-roll anesibopho sokuthwala isisindo samaroli omsebenzi kanye nokuqinisekisa ukuqondanisa okulungile nokulinganisa ngesikhathi sokugoqa. Ngaphandle kwe-roller yokusekela, i-roller yokushisa ngeke ikwazi ukwenza umsebenzi wayo ngokuphumelelayo, okuholela ekungasebenzi kahle kanye nokulimala okungenzeka kwemishini.

Ngokungeziwe ekunikezeni ukwesekwa, lawa marola asiza ukulawula ukujiya nokuma kwezinto ezicutshungulwayo. Lokhu kufinyelelwa ngokuqondanisa okunembayo kanye nokulungiswa kwamarola asekelayo, ukuqinisekisa ukuthi umkhiqizo wokugcina uhlangabezana nezicaciso ezidingekayo kanye namazinga ekhwalithi.

Sekukonke, ama-hot work rolls nama-backup rolls ayingxenye ebalulekile yezinqubo zezimboni, ikakhulukazi ekukhiqizeni insimbi. Ikhono labo lokumelana namazinga okushisa aphezulu kanye nemithwalo esindayo, kanye nendima yabo ekwakheni nasekusekeleni izinto zokwakha, kubenza babaluleke kakhulu ekukhiqizweni kwemikhiqizo yezimboni ehlukahlukene. Ukuqonda ukubaluleka kwalawa ma-roller kanye nokutshala izinto ezisezingeni eliphezulu, ezihlala isikhathi eside kubalulekile ukuze kuqinisekiswe inqubo yokukhiqiza ephumelelayo, ethembekile.
