Ol masin bilong katim 'film' i save gut tru long holim 'film', moa yet long kisim ol 'slitting' risal. Tasol, yumi mas kliagut yet long wok bilong katim ol samting. Yumi mas wok hat long kamapim gutpela wok bilong en long apim prodaksen kapasiti. Yumi ken toktok long hau ol masin bilong katim piksa i ken helpim wok bilong kamapim gutpela samting.
Linear presa bilong presa rola i makim presa we presa rola i putim long pepa rol long taim bilong 'rewinding' proses. Long taim bilong namba wan hap bilong 'rewinding', 'pressure roller' i save givim moa hevi long pepa rol, na i wok wantaim ol 'roller' bilong fran na baksait long givim strong bilong 'rewinding'. Taim 'roll diameter' i go antap, ples bilong 'pressure roller' i go antap isi isi, na presa we 'pressure roller' i putim i go daun isi isi. Taim 'roll diameter' i kamap long wanpela mak, presa we 'pressure roller' i putim i kamap long zero. Long dispela taim, em i wok olsem wanpela samting tasol bilong holim pepa rol i stap gut. Ol i mas makim 'pressure control program' bilong 'pressure roller' bihainim gutpela bilong pepa. Planti taim, presa bilong presa rola i save kamap otomatik bihainim wanpela presa kev we i stap pinis na i no nidim opereta long senisim.
Kontrol bilong 'unwinding' tensen: Taim yu wok long 'rewinding' wanpela grup bilong ol pepa rol, traim long abrusim senisim 'rewinding tension' bilong mekim 'tensen' i wankain insait na ausait long 'slitter rewinder'. Namba tu, sapos ol i bosim 'web tension' i go daun tumas long taim bilong 'rewinding', 'roll' inap long lus o slip long 'bottom roller', na dispela inap long kamapim ol hevi long pepa olsem 'wrinkling' na 'interleaving'. Sapos ol i bosim strong tumas, rol inap long pairap o bagarapim as bilong pepa. Olsem na, em i bikpela samting long holim wanpela 'constant actual tension control value' long taim bilong 'rewinding' proses na long putim wanpela gutpela 'inertia compensation regulator' insait long 'tension closed-loop control system.
