Lub tswvyim ntawm "folding" yog los ntawm German lus, lo lus "fold" hauv kev txhais lus txhais tau tias "groove", "gutter". Lub tswv yim tau pib hauv paus hauv peb cov lus yam tsis muaj kev hloov pauv. Folding yog siv los tsim cov ntawv tshaj tawm, xws li phau ntawv, nplooj ntawv lossis ntawv xa ntawv, nrog rau kev tsim cov ntawv luam tawm tag nrho xws li phau ntawv teev npe lossis phau ntawv.
Folding - yog dab tsi?
Hauv kev lag luam saum toj kawg nkaus, folding (tom qab no hu ua F.) txhais tau tias folding ib daim ntawv nrog cov ntawv luam tawm thiab txhua yam uas yuav tsum tau ua kom qhov khoov yog txawm, tsis muaj kev sib yuav xws li dents, bevels, wrinkles, ntxiv folds, thiab cov zoo li, nrog rau kev nqis peev tom ntej rau hauv phau ntawv uas yuav ua rau ntau yam ntxiv.
Fold Types
Ntau hom F. yog qhov txawv ntawm ntau yam. So:
Nyob ntawm qhov chaw ntawm tus kheej folds rau ib leeg, lawv tuaj yeem ua qhov sib npaug, sib npaug thiab sib xyaw (ua ke) F., thiab tseem muaj qhov sib npaug. Qhov no yog dab tsi? Xws li ib tug khoov, thaum lub fold kab khiav raws nraim nyob rau hauv nruab nrab ntawm daim ntawv folded yav tas los. Piv txwv li, rau cov khoom siv hauv phau ntawv, lawv tsuas yog sivsquare fold type
Nyob ntawm hom quav, raws li qhia hauv daim duab, muaj tsawg kawg yog kaum ob hom sib txawv. Kom paub meej, lawv txhua tus nyob hauv daim duab hauv qab no
Nyob ntawm cov folds (los ntawm ib mus rau plaub, tsis txhob ua ntau quav), cov zis yog phau ntawv nrog plaub, yim, 16 thiab 32 nplooj
Qhov no yog li cas, piv txwv li, ib qho F. perpendicular yuav saib hauv ib qho quav (taw tes a), ob folds (b), peb (c) thiab plaub (d).
Yog, ib zaug khoov daim ntawv, peb tuaj yeem tau daim ntawv qhia; ob zaug - phau ntawv; peb zaug thiab plaub zaug - phau ntawv sau rau tom ntej rau hauv cov ntawv luam tawm nyias thiab tuab dua.
Tseem muaj xws li cov qhab nia. Folding yog ua rau ntawm daim ntawv uas nws qhov ceev tsis tshaj 170 g / m2. Rau cov ntaub ntawv tuab, hom folding no tsis haum, vim nws tuaj yeem ua rau cov txheej txheem saum toj kawg nkaus ntawm cov ntaub ntawv no. Feem ntau qhov kev puas tsuaj zoo li tev xim, tawg lossis creases. Tias yog vim li cas lawv ua crease - lawv thawj zaug thawb daim ntawv raws txoj kab ntawm lub neej yav tom ntej khoov rau qhov zoo tshaj plaws tom ntej F.
Nws tau hais yav dhau los tias qhov quav yuav tsum txawm thiab tsis muaj kev sib yuav. Cia peb saib ntxiv.
Folding quality indicators
- Qhov tseeb ntawm nplooj ntawv (hauv cov ntawv xov xwm, phau ntawv) yog thawj qhov uas tuaj yeem raug ntaus nqi rau cov ntsuas no. Puas tsim nyognyob rau ntawm qhov no, vim nws twb paub meej tias ob peb tus neeg xav nyeem ib phau ntawv uas cov nplooj ntawv tawm ntawm kev sib raug zoo thiab randomly.
- Qhov ntsuas thib ob yog qhov tseeb ntawm qhov folding. Nws suav nrog kev sib npaug ntawm cov teb ntawm cov zos uas nyob ib sab, tsis muaj cosine. Qhov yuam kev raug tso cai - qhov sib txawv ntawm 1.5-2 hli, suav nrog cov qauv ntawm cov ntawv yav tom ntej.
- Qhov ntsuas thib peb yuav yog qhov ntom ntom ntawm txhua daim ntawv ntawm phau ntawv rau tus txha nraub qaum. Nyob ntawm seb qhov degree ntawm compression, qhov ntom yog txiav txim siab raws li tag nrho qhov sib txawv ntawm cov nplooj ntawv khoov.
- Thiab qhov taw qhia kawg yog qhov pom kev zoo, uas yog, qhov tsis muaj wrinkles, wrinkles, irregularities thiab lwm yam tsis xws luag.
Folding Methods
Rau qhov ntim me me ntawm kev ua haujlwm, kev tuav tuav tau tso cai. Nws yog dab tsi? Tshwj xeeb thiab tsis tshua muaj. Txawm hais tias kev khiav me me lossis kev ua haujlwm nyuaj yog tuav los ntawm tes, uas yuav tsum muaj tib neeg qhov tseem ceeb. Txwv tsis pub, xws li kev ua haujlwm yog ua los ntawm lub tshuab ntawm ob hom - riam thiab cassette. Lub hauv paus ntsiab lus ntawm kev ua haujlwm yog tib yam rau lawv - daim ntawv yog dov ntawm lub siab rollers.
Muaj ntau qhov sib txawv ntawm cov chaw no. Qhov sib txawv tseem ceeb ntawm cov tshuab no yog nyob rau hauv ob qhov tsis muaj - hauv qhov tseeb (siab dua rau rab riam), thiab ceev (siab dua rau ib lub cassette). Xav tau sai dua - siv lub kaw lus kaw lus, qhov tseeb yog qhov tseem ceeb - qhov kev xaiv yog rau rab riam.
Qhia kos duab
qhov kev pabcuam no yog ua kom yooj yim ntawm kev thauj cov ntawv tiav lossis lwm cov ntawv loj. Kho daim ntawv foldingyuav ua rau koj txoj haujlwm zoo nyob ntev dua, vim tias yuav tsis muaj creases, tsis tsim nyog scuffs, thiab lwm yam. Ua F. kos duab rau A4 hom, tsawg zaus - rau A3.
Koj tuaj yeem hais cov lus yooj yim hais txog "folding", qhov no yog dab tsi lub tshuab kev folding ntawm nplooj ntawv. Pom zoo, yog tias koj compress koj tus kheej hauv tsev, cov quav tuaj yeem tawm me ntsis crooked ("me ntsis" yog qhov zoo tshaj). Cov txheej txheem no muaj nyob rau hauv yuav luag txhua lub tsev luam ntawv, thiab nws cov nqi raug xam raws li cov khoom xws li:
- txheej txheem ntawm kev ua tiav (tshuab, phau ntawv);
- hom khoov;
- nrawm;
- ntau ntawm kev ua haujlwm thiab nws qhov nyuaj.
Folding - nws yog dab tsi, vim li cas nws thiaj xav tau? Ib tug neeg tuaj yeem nug thiab hnov cov lus teb yooj yim. Qhov no tsis yog tsuas yog qhov yooj yim ntawm kev thauj mus los, tab sis kuj yog ib qho zoo nkauj, huv si, nthuav tawm ntawm koj txoj haujlwm. Rau cov koom haum loj, nws yuav yog qhov tseem ceeb heev uas ib tug neeg yuav tshwm sim nrog txoj haujlwm uas nws kho nrog txhua yam kev saib xyuas, qhov no yog qhov tsawg kawg yog qhov qhia tau tseeb.
