Muchina wekuchekeresa firimu, chinhu chakakosha chemidziyo mukushandura maindasitiri, chakagadzirirwa kunyatsocheka mitsetse mikuru yezvinhu zvitete, zvinochinjika (sepurasitiki, pepa, foil, kana laminates) kuita mitsetse midiki midiki kana mitsetse. Yayo musimboti wekushanda musimboti inotenderera yakatenderedza matanho matatu makuru: Kusunungura, Kutsemura, uye Kudzoreredza.
1. Kusunungura:Maitirwo acho anotanga nehombe master roll, kana kuti jumbo roll, yakaiswa pashaft yekusunungura. Iyo yakaomesesa braking kana dhiraivha sisitimu inodzora kutenderera kweiyi shaft kuti ipe inowirirana, yakatsikirirwa chikafu chewebhu (zvinhu) mumushini. Kuchengetedza kwakaringana uye kunogara kunetsa kwakakosha kudzivirira makwinya, kutambanudza, kana kuputika kwechinhu. Michina yemazuva ano inowanzoshandisa otomatiki tension control masisitimu nekuda kwechinangwa ichi.
2. Kutsemura:Uyu ndiwo moyo wekuvhiya. Iyo dandemutande yakamanikidzwa inopfuura nepachikamu chekutsemura, painochekwa kureba. Pane nzira mbiri dzekutanga dzekucheka:
Razor Slitting/Sear Cutting: Inoshandiswa kune akaonda, mashoma kuomarara mafirimu. Badza rakapinza, rakaita denderedzwa rakamiswa pakona chaiyo richitarisana nesimbi yakaomeswa yeanvil roll. Iyo midziyo inoveurwa zvakachena sezvainopfuura pakati pavo.
Kupwanya (Chibodzwa) Kucheka: Kunoshandirwa kune zvakakora kana zvakanyanya kudzvanya zvinhu. Mashizha maviri akafananidzwa, akaomeswa esimbi akatenderedzwa (kumusoro uye pasi) anobatanidzwa pamwechete. Iyo blade yepamusoro inokora zvinhu, uye blade yepasi inoitsigira, ichigadzira kucheka kwakachena kuburikidza nekudzora kudzvanywa.
Iyo slitting blades inoiswa pane arbors (shafts) ane zvinzvimbo zvinogona kugadziridzwa kuti aise inodiwa slit upamhi nehupamhi hwepamusoro.
3. Kudzosera kumashure:Mushure mekuchekwa, -tambo dzakapatsanurwa dzezvinhu dzinofanirwa kusungirirwa zvakanaka pamacores ega ega kuti dzigadzire mitsetse mitsva, nhete. Izvi zvinoitika pane rewind station. Iwo maviri maitiro makuru ekudzosera kumashure ndeaya:
Center Winding: Iwo macores matsva anofambiswa zvakananga nemota. Izvi zvinopa yakanakisa kutonga kune inorema rolls uye yakakwirira kumhanya.
Surface (Drum) Winding: The slit web inoroverwa pamacores anotsikirirwa pane hombe, -driven driven. Iko kupokana kunobva pachigubhu kunotyaira macores, kuve nechokwadi kusimba kwakafanana uye kuomarara kwakanakisa, kunyanya kumafirimu matete, anotsvedza.
Muchirongwa chese, kutungamira ma roller nema edge-zvidzore zvinoonekwa (EPCs) zvinochengeta dandemutande rakarongeka. Muchina wecentral control system unowiriranisa kumhanya kwezvikamu zvese, zvichiita kuti zvinhu zvifambe zvakatsetseka kubva pakuvhurwa, nemuma slitters, uye kuenda kune rewind shafts, zvichiita kuti pave nemhando yepamusoro-yakapetwa, maronda akanyatsopedzwa akagadzirira kurongedza kana kuenderera mberi nekugadziriswa.
