Chero pave nemahwindo, kwave kudiwa kucheneswa kwemafafitera.
Nhoroondo yekuchenesa hwindo inofambidzana nenhoroondo yegirazi.Nepo pasina anoziva kuti girazi rakatanga kugadzirwa riini kana kupi, rinogona kunge rakatanga kusvika 2nd millennium BC muEgypt yekare kana Mesopotamia.Yaiva, sezviri pachena, isinganyanyi kunyanyozivikanwa kupfuura nhasi, uye yairangarirwa kuva inokosha zvikuru.Rakatoshandiswa mumutsara unoenderana negoridhe muBhaibheri (Jobho 28:17).Unyanzvi hwekupenya kwegirazi hahuna kusvika kusvika pakupera kwezana ramakore rekutanga BC, uye rakazotanga kugadzirwa mukati mekupera kwezana ramakore rechi 19.Apa ndipo payakatanga kushandiswa kugadzira mahwindo.
Mafafitera ekutanga aya aicheneswa nemadzimai epamba kana kuti vashandi, vachishandisa mushonga uri nyore, mugomo wemvura, uye jira.Yakanga isiripo kusvika pakuvakwa kwekuvaka-kutanga muna 1860-kuti kudiwa kwevanochenesa mahwindo kwakauya.
Pamwepo Pakauya The Squeegee
Mukutanga kwema1900, kwaive neChicago squeegee.Zvaisaita semusvina waunoziva uye waunoda nhasi.Yakanga yakakura uye ichirema, iine 12 screws yaidiwa kusunungura kana kushandura mashizha maviri epingi.Yakanga yakavakirwa pamidziyo yaishandiswa nevabati vehove kukwenya matumbu ehove kubva pazvikepe.Idzi dzaive mamiriro ehunyanzvi kusvika 1936 apo mutorwa wekuItaly anonzi Ettore Steccone akagadzira nekupa patent yemazuva ano squeegee, munoziva, chishandiso chakagadzirwa nendarira yakareruka, ine imwe yakapinza, inochinjika rabha blade.Nenzira yakakodzera, yakanzi "Ettore."Zvinotyisa, Ettore Products Co. ichiri mutungamiriri anotungamira wemazuva ano squeegee, uye ichiri kufarirwa pakati pevashandi.Ettore inofanana zvachose nezvinhu zvese kuchenesa hwindo uye hwindo.
Nhasi Techniques
Iyo squeegee yaive sarudzo yakasarudzika yekushandisa yekuchenesa mahwindo kusvika kutanga kwema1990s.Pakabva pasvika mvura yekudyiswa danda system.Aya masisitimu anoshandisa matangi emvura akacheneswa kudyisa mvura yakacheneswa kuburikidza nematanda marefu, ayo anobva akwesha nekusukurudza tsvina kure nekuoma pasina simba achisiya pasina mitsetse kana smears.Matanda, anowanzo gadzirwa kubva kugirazi kana kabhoni fiber, anogona kusvika kusvika 70 ft, kuitira kuti vanochenesa mahwindo vagone kushanda mashiripiti avo vakamira zvakachengeteka pasi.Iyo mvura inodyiswa pole system haina kuchengetedzeka chete, asiwo inochengeta mahwindo akachena kwenguva yakareba.Hazvishamisi kuti makambani mazhinji ekuchenesa mahwindo nhasi anosarudza iyi system.
Ndiani anoziva kuti teknolojia yeramangwana inogona kubata chii, asi chinhu chimwe ndechechokwadi: chero bedzi pane mahwindo, pachava nekudiwa kwekuchenesa mahwindo.
