Umhlangano wangaphambili wokubamba abanikazi bangaphambili owawusetshenziswa embonini yokucwilisa i-latex ukuze kukhiqizwe imikhiqizo ecwilisiwe ye-latex njengamagilavu e-latex ahlanganisa: Okungenani ubakaki owodwa omise okwe-U onembobo eyodwa eqondile emaphethelweni amabili aqondile ukuze ibhawudi noma induku ebalulekile idlule ezimbobeni 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 ku-pivotal rod 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. Ulayini ophindwe kabili wengalo u-L noma isakhiwo sengalo yezindlu esixhuma i-shaft emide kanye nolayini wokukhiqiza amagilavu kunika amandla umbambi wangaphambili onamathiselwe ekugcineni kwekepisi yenkomba ekabili yangaphambili ukuthi ajikeleze futhi azinzile ezindaweni ezimbili okusiza ukunciphisa ukudlula amagilavu phakathi nenqubo yokuhlubula amagilavu nokwendlaleka.
