Isibani senkungu sangaphambilini yisibani semoto semoto esenzelwe ukukhazimula ngogongolo lwe-strip. Ugongolo luvame ukuklanywa ukuba lube nephuzu elibukhali elinqunyiwe phezulu, futhi ukukhanya kwangempela kuvame ukufakwa ngaphansi futhi kuhloswe ngawo nge-angle ebuhlungu. Ngenxa yalokhu, izibani zenkungu zincike endleleni, zithumela ukukhanya emgwaqweni futhi zikhanyise umgwaqo esikhundleni sesendlalelo senkungu. Isikhundla kanye nokuqagela kwezibani zenkungu kungaqhathaniswa futhi kuqhathaniswe nogongolo oluphezulu nezibani eziphansi zokukhanya ukwambula kahle ukuthi la madivayisi abonakala ahlukile kangakanani. Zombili izibani eziphakeme eziphakeme neziphansi zihlose ama-engeli angajulile, zibavumele zikhanyise umgwaqo kude kakhulu nemoto. Ngokuphambene, ama-engeli aqine asetshenziswa izibani zenkungu asho ukuthi zikhanyisa kuphela umhlabathi ngqo phambi kwemoto. Lokhu ukuqinisekisa ububanzi bokudutshulwa kwangaphambili.
