Indibano yangaphambili yokubamba abanini ngaphambili ababesetyenziswa kushishino lokudipha i-latex kwimveliso yeemveliso zelatex diphu ezifana neeglavu zelatex ezibandakanya: Ubuncinane isibiyeli esinye esibunjwe ngu-U esinomngxuma omnye ogxininise kwiziphelo zombini ezime nkqo ukuze ibholithi okanye intonga ebalulekileyo idlule kwimingxuma kwaye ibotshelelwe ngokukhuselekileyo kwisibiyeli.

Iingalo ezimbini ezimile okwe-L ezibandakanya isahlulo esime nkqo kunye nesiseko esisebenza njengenxalenye yendibano yangaphambili yabanini. Isiphelo esiphezulu sesahlulo esime nkqo seengalo ezimilise okwe-L sifakwe ngokukhuselekileyo kwi-pivotal rod yesibiyeli esimilise u-U apho isiphelo esikhululekileyo sesahlulo sesiseko siyilelwe ukubamba ubuncinane umnini wangaphambili omnye.

I-double indexing cap yangaphambili iquka i-roller disc, i-indexing cap yokuqala, i-indexing cap yesibini, i-shaft emide, i-spring yangaphambili yomnini kunye nesakhiwo sengalo yezindlu. I-roller disc ye-double indexing cap yangaphambili umnini udityaniswa ne-indexing cap yokuqala. Isalathisi sesibini sesalathisi sifakwe kwi-captioning indexing yokuqala kwaye inobuncinci ubuso obuncinci kwicala. Ukongeza, imiphetho ephezulu yesikhombisi sesalathisi sesibini siyanwenwela ukuze kuqhelaniswe ngokufanelekileyo nabayili beglavu kwinkqubo yokwenziwa kweeglavu. I-shaft emide ifakwe kwiplati yokukhiya kwelinye icala, elibandakanya i-roller disc. Ipleyiti yokutshixa ye-shaft eyandisiweyo idityaniswe ne-roller disc isebenzisa i-EPDM (i-ethylene propylene diene monomer rubber) okanye i-silicon sheet, efakwe phakathi kwepleyiti yokutshixa kunye ne-roller disc. Isiphelo sesibini se-shaft eyandisiweyo ifakwe kwelinye icala lesakhiwo sengalo yezindlu. Ulwakhiwo lwengalo yendlu edibanisa ishafti eyongeziweyo kunye nomgca wokwenza iiglavu ngumgca ophindwe kabini we-L. Inani leebheringi libonelelwe phakathi kweziphelo zesakhiwo sengalo yendlu kunye neshafti eyandisiweyo ukwenzela ukuba kube lula ukuhamba kweshafti eyoluliweyo ecaleni komgca wokuvelisa iiglavu. Imithombo yangaphambili yesibambi ibekwe malunga neshafti eyongeziweyo kwaye isivalo sentwasahlobo simisa intwasahlobo kwisiphelo esiphezulu seshafti emide kufutshane nesakhiwo sengalo yendlu. Umgca wengalo we-L ophindwe kabini okanye isakhiwo sengalo yendlu edibanisa i-shaft eyandisiweyo kunye nomgca wokuvelisa iglavu yenza ukuba umnini wangaphambili uncanyathiselwe ekupheleni kwe-capture indexing cap yangaphambili ukuba ijikeleze kwaye izinzile kwiindlela ezimbini zokuqhelaniswa ezinceda ukunciphisa ukudlula kweeglavu ngexesha lokuhluthwa kweglavu kunye nenkqubo yokubeka.
