Nrog gutters, cov saws yuav tsum zoo ruaj ntseg thiab tensioned nyob rau hauv tus ncej. Thaum ua hauj lwm nrog weakly tensioned saws, ib tug shard nyob rau hauv daim ntawv ntawm ib tug wavy txiav, thiab lwm yam. Txoj kev siv ntau tshaj plaws ntawm tensioning lub saw yog los ntawm txoj hlua khi, eccentric, ntsia hlau (daim duab 1), nrog rau txoj kev tensioning los ntawm kev siv hydraulic. Tightening saw nrog wedges yog phem dua li lwm txoj kev. Ib tug loj tus naj npawb ntawm industries tsim ib tug loj tus naj npawb ntawm hom muaj zog, ceev-tsav, ua tau zoo heev saws. Cov sawmills uas muaj txiaj ntsig zoo no ua haujlwm hauv cov ntoo ua ntoo loj hauv kev tsim kho kev lag luam. Cov yam ntxwv ntawm cov gaiters no tau muab rau hauv rooj 1.

Cov khoom tsim tau ntawm gater yog xam raws li tus qauv: P = K - Δtnq / 1000L m3. Qhov twg K yog tus gater siv coefficient. Rau mechanized turners, K = 0.93, thiab rau semi-mechanized ones, K = 0.90; Δ - hloov mus rau ib qho tig ntawm lub rooj vag ncej; n - tus naj npawb ntawm cov kiv puag ncig ntawm lub qhov rooj ncej ib feeb; t - khaws lub sijhawm ua haujlwm hauv feeb; q - log volume, m3; L - ntev ntawm cov cav, m.
Thaum txiav txim siab qhov nruab nrab ntawm cov khoom lag luam txhua xyoo ntawm kev sib tw rau ib qho kev hloov pauv, kev nres uas tshwm sim vim muaj ntau yam ua rau (kho, tsis muaj cov khoom siv raw, thiab lwm yam) yuav tsum raug coj mus rau hauv tus account. Cov kev poob no yog txiav txim los ntawm kev sim coefficient Kvaj tswv = 0.9 - 0.92.
Yog li ntawd, qhov nruab nrab txhua xyoo kev tsim khoom ntawm tus neeg saib xyuas rau ib qho kev hloov pauv yog txiav txim los ntawm cov qauv P = Kvaj tswv x K x Δntq/1000L m3 rau ib qho kev hloov.

Saws yog ua nyob rau hauv ob tug hniav profiles: nrog ib tug tawg rov qab ntug thiab nrog ib tug ncaj rov qab ntug (daim duab 2). Thaum xaiv qhov xav tau qhov ntev ntawm lub saw, koj yuav tsum tau coj los ntawm qhov ntev ntawm lub thav duab ntawm lub gater, qhov loj ntawm nws cov hlab ntsha thiab txoj kab uas hla ntawm cov cav yuav raug txiav. Qhov ntev ntawm cov saw tuaj yeem txiav txim siab los ntawm cov mis L = Dmax + H + (300 txog 350) mm, qhov L yog qhov ntev ntawm cov saw, mm; Dmax - qhov siab tshaj plaws ntawm cov cav yuav raug txiav; 300 - 350 - nyiaj pub dawb vim kev teeb tsa ntawm cov ntawv ntxig rau cov laug cam thiab slats; H - stroke qhov siab, mm.

Cov saws raug ntsia ua ke nrog stirrups uas txuas mus rau qis kawg ntawm lub saw thiab nrog ib txheej ntawm ob stirrups thiab xya bolts rau sab sauv kawg. Cov stirrups yog txuas mus rau lub saw ntawm txoj cai kaum rau nws sab nraub qaum. Lub beveled ntug ntawm lub stirrup yuav tsum tig mus rau ib leeg. Ua ntej riveting lub stirrup, cov npoo ntawm cov saw yuav tsum tau kuaj xyuas seb lawv ncaj thiab sib npaug, thiab yog tias lawv tsis yog, lawv yuav tsum tau muab txiav rau ntawm lub tshuab saws.
