Umshini wokusika ifilimu, ucezu lwesisetshenziswa esibalulekile ekuguquleni izimboni, uklanyelwe ukusika ngokunembile amaroli amakhulu ezinto ezincanyana, eziguquguqukayo (njengepulasitiki, iphepha, ucwecwe, noma amalayini) abe yimichilo emincane eminingi noma amaroli. Umgomo wayo oyinhloko wokusebenza uzungeza izigaba ezintathu eziyinhloko: Ukuqaqa, Ukusika, kanye Nokuhlehlisa.
1. Ukukhulula:Inqubo iqala nge-master roll enkulu, noma i-jumbo roll, efakwe ku-shaft yokukhulula. Isistimu yokubhuleka eyinkimbinkimbi noma yokushayela ilawula ukuzungezisa kwale shaft ukuze inikeze okuphakelayo okungaguquki, okuqinile kwewebhu (okubalulekile) emshinini. Ukugcina ukungezwani okunembile nokuqhubekayo kubalulekile ukuvimbela imibimbi, ukwelula, noma ukunqamuka kwezinto. Imishini yesimanje ivamise ukusebenzisa izinhlelo zokulawula ukushuba okuzenzakalelayo kule njongo.
2. Ukusika:Lena inhliziyo yokuhlinzwa. Iwebhu egxilile idlula esigabeni sokusika, lapho isikwa khona ngobude. Kunezindlela ezimbili eziyinhloko zokusika:
I-Razor Slitting/Shear Cutting: Isetshenziselwa amafilimu azacile, aqinile kancane. I-razor blade ecijile, eyindilinga ibekwe nge-engeli eqondile ngokumelene ne-anvil roll yensimbi eqinile. Impahla igundwa ngokuhlanzekile njengoba idlula phakathi kwayo.
Crush (Amaphuzu) Ukusika: Isetshenziselwa izinto eziwugqinsi noma ezicindezelwa kakhulu. Izindwani ezimbili ezilinganayo, eziqinile eziyindilinga (phezulu naphansi) ahlanganiswe ndawonye. I-blade ephezulu ifaka amaphuzu okubalulekile, futhi i-blade engezansi iyayisekela, idale ukusika okuhlanzekile ngokucindezela okulawulwayo.
Ama-slitting blades afakwe kuma-arbors (ama-shafts) izikhundla zawo zingashintshwa ukuze zisethe ububanzi obufunwayo bokusika ngokunemba okuphezulu.
3. Ukubuyisela emuva:Ngemva kokusika,{0}}izintambo zezinto ezibonakalayo manje{0}ezihlukanisiwe kufanele ziboshwe ngobunono kuma-cores ngamanye ukuze kwakheke amaroli amasha, amancane. Lokhu kwenzeka esiteshini sokuhlehlisa. Izindlela ezimbili eziyinhloko zokubuyisela emuva yilezi:
I-Center Winding: Ama-cores amasha ashayelwa yi-motor ngqo. Lokhu kunikeza ukulawula okuhle kakhulu kwamaroli asindayo nesivinini esikhulu.
Ukujikajika kwendawo (Isigubhu): I-slit web ilinyazwa kuma-cores acindezelwa esigubhini esikhulu,{0}}esishayelwa yinjini. Ukungqubuzana okuvela esigubhu kushayela ama-cores, kuqinisekisa ukucinana okufanayo kanye nokuqina okuhle kakhulu kwe-roll, ikakhulukazi kumafilimu azacile, ashelelayo.
Kuyo yonke inqubo, amarola aqondisayo kanye{0}}nezinzwa zendawo (EPCs) zigcina iwebhu iqondaniswe ngendlela efanele. Isistimu yokulawula emaphakathi yomshini ivumelanisa isivinini sazo zonke izigaba, iqinisekisa ukugeleza kwezinto ezibushelelezi kusukela ekukhumulweni, ngokusebenzisa ama-slitters, kanye nokungena kuma-shafts ahlehlisayo, okuholela{2}}ezinhlelweni eziningi eziningi, amaroli aqedwe aboshwe ngokuqinile alungele ukupakishwa noma ukucutshungulwa okwengeziwe.
