Ngethuba kukho iifestile, bekukho imfuneko yokucoca iifestile.
Imbali yokucoca ifestile ihamba kunye nembali yeglasi. Ngelixa kungekho mntu wazi ngokuqinisekileyo ukuba yenziwa nini okanye phi iglasi okokuqala, kusenokwenzeka ukuba yaqala emva ukuya kuthi ga kwi-2 leminyaka ye-BC kwi-Egypt yakudala okanye eMesopotamiya. Ngokucacileyo, yayiyinto eqhelekileyo kakhulu kunanamhlanje, kwaye yayigqalwa njengexabiseke kakhulu. Kwade kwasetyenziswa kwisivakalisi esihambisana negolide eBhayibhileni ( Yobhi 28:17 ). Ubugcisa bokuvuza kweglasi abuzange bufike de kwangaxeshanye ngasekupheleni kwenkulungwane yoku-1 BC, kwaye ekugqibeleni baqalisa ukuveliswa ngobuninzi phakathi ukuya ekupheleni kwenkulungwane ye-19. Oku kuxa yaqala ukusetyenziswa ukuvelisa iifestile.
Ezi festile zokuqala zazicocwa ngabafazi bamakhaya okanye izicaka, ngesisombululo esilula, ibhakethi lamanzi kunye nelaphu. Kwakungekho de kwabakho i-boom yolwakhiwo-ukuqala ngo-1860-ukuba imfuno yabacoci beefestile yeza.
Emva koko kwafika iSqueegee
Ekuqaleni kwee-1900s, kwakukho i-Chicago squeegee. Ibingajongeki njenge squeegee oyaziyo noyithandayo namhlanje. Yayinkulu kwaye inzima, inezikrufu ezili-12 ezifunekayo ukukhulula okanye ukutshintsha iincakuba ezimbini ezipinki. Yayisekelwe kwizixhobo ezazisetyenziswa ngabalobi ukukhuhla amathumbu entlanzi kwidekhi yesikhephe. Ezi zaziyimeko yobugcisa de kwangowe-1936 xa ummi wase-Italiya ogama lingu-Ettore Steccone wayila kwaye enelungelo elilodwa lomenzi we-squeegee yanamhlanje, uyazi, isixhobo esenziwe ngobhedu olukhaphukhaphu, kunye nencakuba enye ebukhali, ebhetyebhetye yerabha. Ngokufanelekileyo, yabizwa ngokuba yi "Ettore." Okothusayo kukuba, i-Ettore Products Co. isengumboneleli okhokelayo we-squeegee yanamhlanje, kwaye iseyintandokazi phakathi kweengcali. I-Ettore ifana ngokupheleleyo nazo zonke izinto zefestile kunye nokucoca ifestile.
IiTeknikhi zanamhlanje
I-squeegee yayiyeyona nto ikhethiweyo yesixhobo sokucoca iifestile kude kube sekuqaleni kwee-1990s. Emva koko kwafika inkqubo yeepali ezityiswa ngamanzi. Ezi nkqubo zisebenzisa iitanki zamanzi adiyiniweyo ukondla amanzi acociweyo ngeepali ezinde, ezithi emva koko zixukuxe kwaye zihlambulule ukungcola kwaye zome ngaphandle komzamo zingashiyi streaks okanye smears. Izibonda, ezidla ngokwenziwa ngeglasi okanye kwifayibha yekhabhoni, zinokufikelela kwi-70 ft, ukuze abacoci beefestile bakwazi ukwenza umlingo wabo bemile ngokukhuselekileyo emhlabeni. Isixokelelwano sepali esondliwe ngamanzi asikhuselekanga nje kuphela, kodwa sikwagcina iifestile zicocekile ixesha elide. Akumangalisi ukuba iinkampani ezininzi zokucoca iifestile namhlanje zikhetha le nkqubo.
Ngubani owaziyo ukuba yeyiphi iteknoloji yexesha elizayo enokuthi ibambe, kodwa into enye iqinisekile: ngokude nje kukho iifestile, kuya kubakho imfuneko yokucoca ifestile.
