Yam ntxwv cuam tshuam rau kev ua kom nruj
(1) Kev hloov pauv ntawm kev ceev ntawm lub tshuab
(2) Hloov cov kev nruj ntawm cov khoom raw yob
(3) Thaum lub sij hawm rewinding thiab unwinding txheej txheem ntawm cov slitter, txoj kab uas hla ntawm rewinding thiab unwinding yog hloov tas li, thiab qhov hloov ntawm txoj kab uas hla yuav ua rau kev hloov pauv ntawm cov khoom tawg.
(4) Qhov tsis sib xws ntawm cov khoom ntawm txiav cov khoom siv. Piv txwv li, elasticity ntawm cov khoom hloov, cov tuab ntawm cov khoom hloov raws qhov dav thiab ntev.
(5) Kev sib kis ntawm cov tshuab slitter muaj cov laj thawj xws li tsis txaus thiab tsis khov cua hloov.
