Umhlangano wangaphambili wokubamba abanikazi bangaphambili owawusetshenziswa embonini yokucwilisa i-latex ukukhiqizwa kwemikhiqizo ecwilisiwe ye-latex efana namagilavu ​​e-latex ahlanganisa: Okungenani ubakaki owodwa omise okwe-U onembobo eyodwa yokugxila emikhawulweni ngayinye emibili eqondile ukuze ibhawudi. noma induku ebalulekile ingadlula emigodini futhi iboshwe ngokuvikelekile kubakaki.

Izingalo ezimbili ezimise okwe-L ezihlanganisa ingxenye eqondile kanye nengxenye eyisisekelo esebenza njengengxenye yomhlangano wabanikazi bangaphambili. Ingxenye engaphezulu yengxenye eqondile yezingalo ezimise okwe-L ifakwe ngokuvikelekile entweni eyinhloko yabakaki abamise oku-U lapho isiphetho samahhala sengxenye eyisisekelo siklanyelwe ukubamba okungenani umnikazi wangaphambili oyedwa.

Ikepisi elinenkomba ekabili yangaphambili ihlanganisa i-roller disc, i-indexing cap yokuqala, i-indexing cap yesibili, i-shaft emide, isiphethu sangaphambili somnikazi kanye nesakhiwo sengalo yendlu. I-roller disc ye-double indexing cap yangaphambili yomphathi ihlanganiswe ne-indexing cap yokuqala. Ikepisi lesibili lokukhomba linamathiselwe kukepisi lokuqala lokukhomba futhi okungenani linendawo eyodwa eyisicaba eceleni. Ukwengeza, imiphetho ephezulu yesivalo senkomba sesibili siyanwebeka ukuze kuqondiswe kahle amagilavu ​​enqubweni yokukhiqiza amagilavu. I-shaft emide ixhunywe kwipuleti yokukhiya ekugcineni, ehlangene ne-roller disc. Ipuleti lokukhiya le-shaft emide lihlanganiswe ne-roller disc kusetshenziswa i-EPDM (i-ethylene propylene diene monomer rubber) noma ishidi le-silicon, elifakwa phakathi kwepuleti lokukhiya ne-roller disc. Umkhawulo wesibili we-shaft emide unamathele engxenyeni eyodwa yesakhiwo sengalo yezindlu. Isakhiwo sengalo yezindlu esixhuma i-shaft emide kanye nolayini wokukhiqiza amagilavu ​​umugqa ophindwe kabili we-L. Inani lamabheringi lihlinzekwa phakathi kwamaphethelo esakhiwo sengalo yendlu kanye neshafti emide ukuze kuzuzwe ukunyakaza okulula kweshafti emide eduze komugqa wokukhiqiza amagilavu. Isiphethu sangaphambili sesibambi simi eduze kwe-shaft emide futhi isivalo se-spring simisa isiphethu ekugcineni okuphezulu kwe-shaft emide eduze nesakhiwo sengalo yezindlu. Umugqa ophindwe kabili wengalo u-L noma uhlaka lwengalo yendlu oluxhuma i-shaft emide kanye nolayini wokukhiqiza amagilavu ​​lwenza umnikazi wangaphambili onamathiselwe ekugcineni kwekepisi enenkomba ephindwe kabili ukuthi ajikeleze futhi azinze ezindaweni ezimbili okusiza ukunciphisa ukudlula amagilavu ​​phakathi ukuhlubula amagilavu ​​kanye nenqubo yokubeka izingqimba.
