futhi ibambe iqhaza elibalulekile ekubumbeni nasekulolongeni insimbi ibe yimikhiqizo ehlukahlukene. Phakathi kwezinhlobo ezahlukene zamaroli asetshenziswa kule nqubo, ama-forged rolls, ama-work rolls, ama-back-up roll nama-back-up rolls ayisihluthulelo esithinta ukusebenza kahle kanye nekhwalithi yesigayo esishisayo.

Ama-roller akhiwe akhiqizwa ngenqubo yokubumba nokucindezela insimbi ngaphansi kwengcindezi ephezulu, okuholela ku-roller eminyene futhi eqinile. Lawa ma-roll aziwa ngamandla awo kanye nekhono lawo lokumelana nezimo ezimbi kakhulu zezigayo ezishisayo, okuwenza alungele imisebenzi enzima ehilelekile kule nqubo.

Amaroli okusebenza angolunye uhlobo olubalulekile lwamaroli asetshenziswa ezigayweni eziginqikayo ezishisayo futhi anomthwalo wemfanelo wokufaka ingcindezi ensimbi ukuze igxumeke futhi ilolonge ngokuvumelana nezimfuneko ezidingekayo. Lawa ma-roller angaphansi kwemithwalo ephezulu namazinga okushisa, okudinga ukuthi abe nokuhle kakhulu ukumelana nokugqoka kanye nokuzinza kokushisa ukuze kuqinisekiswe ukusebenza okungaguquki.

Ama-backup rolls ahlinzeka ngokusekela nokulinganisela kuma-roll rolls, okusiza ukugcina ukuzinza nokunemba kwenqubo yokugoqa. Lawa ma rolls aklanyelwe ukumelana namandla amakhulu asetshenziswa ngesikhathi sokuginqiswa okushisayo kwezinsimbi, okuwenza abe yingxenye ebaluleke kakhulu ekuqinisekiseni ikhwalithi nokunemba komkhiqizo wokugcina.

Njengoba igama liphakamisa, ama-backup rolls ahlinzeka ngokusekela okwengeziwe kumaroli omsebenzi nama-backup rolls, okusiza ukuthuthukisa ukusebenza kahle kanye nokusebenza kahle kwesigayo esishisayo. Lawa maroli aklanyelwe ukuphatha amandla asemaceleni futhi aqinisekise ukuqondanisa okufanele kwamanye amaroli, ngaleyo ndlela kuthuthukiswe ukusebenza kukonke kwenqubo yokugoqa.

Kafushane, izinhlobo ezahlukene zamaroli, okuhlanganisa amaroli afojiwe, ama-work rolls, ama-back-up rolls, nama-back-up rolls, abalulekile ekusebenzeni ngempumelelo kwesigayo esishisayo. Izakhiwo namakhono abo ahlukile asiza ukuthuthukisa ikhwalithi iyonke, ukusebenza kahle kanye nokunemba kwenqubo yokwenza insimbi, okubenza babe yingxenye ebalulekile embonini yokukhiqiza.
