Lub tshuab rewinding ntawv siv ntau yam khoom siv kho tshuab thiab cov tshuab tswj hwm los nthuav daim ntawv loj uas muab tso rau ntawm lub khib ntawv rov qab, coj los ntawm lub menyuam qhia ntawv, thiab nkag mus rau hauv qhov chaw rewinding. Thaum lub sijhawm rewinding, daim ntawv nyoos raug rewound nruj thiab sib npaug rau hauv ib qho kev qhia tshwj xeeb ntawm daim ntawv so quav los ntawm kev kho cov kev teeb tsa xws li qhov ceev, siab, thiab kev nruj ntawm lub menyuam rewinding. Tib lub sijhawm, qee lub tshuab rewinding kuj muaj cov haujlwm xws li embossing, punching, thiab kua nplaum txau kom tau raws li ntau yam kev xav tau ntawm cov neeg siv sib txawv rau cov khoom ntawv so quav.
Cov qauv dav dav
1880 hom: qhov loj tshaj plaws ntawm daim ntawv yog 2200 hli, qhov tsawg kawg nkaus ntawm daim ntawv yog 1000 hli, haum rau cov lag luam me thiab nruab nrab thiab cov tib neeg, nrog rau qhov zoo hauv kev xaiv cov khoom siv raw, uas tuaj yeem ua rau kom muaj ntau lawm thaum txo cov khoom poob ntawv.
2200 tus qauv: Lub tshuab ua ntawv so quav 2200 ua los ntawm cov hlau phaj huv si khiav ruaj khov thiab tsim nyog rau cov neeg pib tshiab nrog kev nqis peev me me thiab qhov chaw me me. Nws tuaj yeem ua ke nrog cov tshuab txiav ntawv tes thiab cov tshuab kaw dej txias los tsim kwv yees li ob thiab ib nrab tons ntawm ntawv so quav hauv 8 teev.
3000 hom: Nrog rau cov zis loj txog li 6 tons hauv 8 teev, nws tsim nyog rau cov neeg siv khoom uas nrhiav kev tso zis thiab tsis xav hloov cov khoom siv. Nws feem ntau nruab nrog cov tshuab txiav ntawv tsis siv neeg thiab cov tshuab ntim khoom tsis siv neeg, thiab ua haujlwm ntawm kab sib dhos tag nrho kom txuag tau cov neeg ua haujlwm thiab kev poob.
