Rolling force: Nws tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev txo cov ntaub ntawv foil nrog lub thickness ntawm 0.05mm lossis ntau dua. Txij li thaum tus nqi txo yog loj dua thaum lub sij hawm txo-dhau ntau lawm, thiaj li yuav xyuas kom meej qhov sib npaug ntawm lwm cov txheej txheem tsis, lub dov quab yuam kuj siv loj dua.
Rolling ceev: Rolling ceev yog lub ntsiab qhia ntawm kev nce qib ntawm dov mills thiab dov tshuab. Txoj kev loj hlob ntawm aluminium foil dov mills yog high-speed dov kom tau txais kev tsim khoom siab. Txawm li cas los xij, thaum txo tus naj npawb ntawm cov hla dhau hauv kev tsim khoom, qhov kev txo qis ntawm thawj ob kis loj, qhov deformation tshav kub thiab kev sib txhuam kub yog qhov loj, thiab yog tias lub dov ceev ceev heev, nws yooj yim los ua bulging.
