Makina opaka filimu, chida chofunikira kwambiri potembenuza mafakitale, amapangidwa kuti azidula bwino mipukutu yayikulu ya zinthu zoonda, zosinthika (monga pulasitiki, mapepala, zojambulazo, kapena zoyala) kukhala timizere tambirimbiri tating'onoting'ono. Mfundo yake yayikulu yogwirira ntchito imazungulira magawo atatu: Kumasula, Kudula, ndi Kubwereranso.
1. Kumasuka:Ntchitoyi imayamba ndi mpukutu waukulu, kapena kuti jumbo roll, woikidwa pamtengo wopumula. Makina apamwamba a braking kapena drive system amawongolera kuzungulira kwa shaft iyi kuti apereke chakudya chokhazikika, chokhazikika cha intaneti (zinthu) mumakina. Kusunga kukhazikika kokhazikika komanso kosalekeza ndikofunikira kuti mupewe makwinya, kutambasula, kapena kukwapula kwa zinthuzo. Makina amakono nthawi zambiri amagwiritsa ntchito njira zowongolera kupsinjika pazifukwa izi.
2. Kudula:Uwu ndiye mtima wa opareshoni. Ukonde wokhazikika umadutsa pagawo la slitting, pomwe umadulidwa motalika. Pali njira ziwiri zoyambira zoslira:
Kudula kwa Razor/Kumeta ubweya: Amagwiritsidwa ntchito popanga makanema owonda kwambiri, osakhazikika. Lumo lakuthwa, lozungulira, limayikidwa molunjika bwino poyang'ana mpukutu wachitsulo cholimba. Zinthuzo zimametedwa bwino zikamadutsa pakati pawo.
Crush (Score) Kudula: Kugwiritsidwa ntchito popanga zinthu zokhuthala kapena zopindika kwambiri. Masamba awiri ofananira, olimba achitsulo ozungulira (pamwamba ndi pansi) amalumikizidwa palimodzi. Tsamba lapamwamba limalemba zakuthupi, ndipo tsamba lapansi limachirikiza, kupanga kudula koyera kupyolera mu mphamvu yoyendetsedwa.
The slitting masamba wokwera pa arbors (mitsinje) amene malo akhoza kusinthidwa kuika ankafuna anatumbula m'lifupi ndi mkulu molondola.
3. Kubwerera m'mbuyo:Pambuyo pocheka, -zingwe zopatukanazi ziyenera kukulungidwa bwino pazigawo zing'onozing'ono kuti zikhale zatsopano, zopapatiza. Izi zimachitika pa rewind station. Njira ziwiri zazikulu zobwezera ndi:
Kumangirira Pakati: Ma cores atsopano amayendetsedwa mwachindunji ndi mota. Izi zimapereka kuwongolera kwabwino kwa ma rolls olemetsa komanso kuthamanga kwambiri.
Mapiringidwe Pamwamba (Drum): Ukonde wong'ambika umakulungidwa m'makola omwe amakanikizidwa ndi ng'oma yayikulu, -yoyendetsedwa ndi injini. Kukangana kochokera ku ng'oma kumayendetsa ma cores, kuwonetsetsa kulimba kofanana ndi kulimba kwabwino kwa gudumu, makamaka pamakanema owonda, oterera.
Munthawi yonseyi, ma roller owongolera ndi m'mphepete-zowonetsa positi (EPCs) zimathandizira kuti intaneti ikhale yogwirizana bwino. Makina owongolera apakati amalumikiza liwiro la magawo onse, kuwonetsetsa kuti zinthu zikuyenda bwino kuchokera potsegula, kudzera pa ma slitters, ndi kulowa m'ma shafts obwerera m'mbuyo, zomwe zimapangitsa kuti -pakhale mipukutu yambiri yapamwamba, yotsekedwa mwamphamvu yokonzeka kupakidwa kapena kukonzedwanso.
