Ngemuva kokuthi ubude beziphu bubhekisela ekuhlanganisweni kobude beziphu ngaphansi kwesimo semvelo se-flat, ngokusho kwesicelo sangempela.Ngokusho kwezinhlobo ezahlukene ze-zipper, umqondo wobude beziphu uhluke kancane.Ngaphansi kwezinhlobo ezihlukene zomqondo wobude beziphu, okufaka uziphu ovula-end, uziphu evala, indawo evulekile ephindwe kabili (noma ebizwa ngokuthi uziphu yendlela evulekile engu-2), uziphu ovale kabili.
Uziphu ovulekile
Ubude be-zipper evulekile busuka ekugcineni kwe-bolt kuya kusilayidi, kungabandakanyi phezulu kwebhande lendwangu.
Uziphu wokuphela okuvaliwe
Ubude beziphu yokugcina evaliwe busuka kusitobhi kuya kusilayida, okungabandakanyi itheyiphu engaphezulu nephansi.
Oziphu abavuleke kabili (noma ababizwa ngokuthi uziphu wendlela evulekile engu-2)
Ubude balolu hlobo lweziphu busuka kusilayida esingezansi kuye kusilayida esiphezulu.
uziphu ovala kabili
Uziphu wokugcina ovaliwe kabili ungahlukaniswa ngo-X no-O. Wonke anamadonsa amabili.Ubude beziphu ezivaliwe ze-X busuka kwesinye isivalo kuya kwesinye.Ubude bomkhawulo ovaliwe we-O uziphu busuka ekugcineni kwesinye isilayidi seziphu ukuya kwesinye isilayidi.
Ukubekezelelana okuvunyelwe
Lapho ama-zipper esenqubo yokukhiqiza, ijubane lomshini, izimo zenqubo kanye nokungezwani kwebhande lamaketanga, kuzoba nokubekezelelana kwemvelo, futhi lapho ubude be-zipper buba bude, ukubekezelelana kwayo kukhulu.
