Imininingwane yokudweba

Yini i-"UN" Thread?

Iphrofayili yochungechunge lwe-American National (i-engeli yephrofayela engu-60 kanye no-H/8 flatness) ihlukile kuphrofayela yochungechunge lwe-Wyeth (i-engeli yephrofayela engu-55 nobude obucaba obungu-H/6).I-American National Thread isetshenziswa kabanzi ezifundeni nasezimbonini ezithonywa imboni yaseMelika.EMpini Yomhlaba Yesibili, ngenxa yezindinganiso zentambo ezingahambisani ezisetshenziswa ama-Allies, ubunzima bokunikezwa kwempahla bubangele ukulahlekelwa okukhulu kwezomnotho kanye nezilimazo kuma-Allies.Ngokushesha ngemva kokuphela kweMpi Yezwe II, i-United States, i-United Kingdom, i-Canada kanye nezinye izinhlangano ezihlangene ngokushesha zaqala ukwenza indinganiso yentambo ebumbene phakathi kwamazwe ahlangene, futhi yamemezela indinganiso yentambo ebumbene ngo-1948.

Ngenxa yokuthi amandla ezomnotho namandla ezempi e-United States ayebusa amabutho Ahlangene ngaleso sikhathi, intambo ebumbene yakhiwa ngokuyinhloko ngokwezinga lentambo kazwelonke yase-United States.Ubunye"; incwadi yokugcina ethi "N" isuselwa kugama elithi "N" le-American National Threads. Kusukela lapho, intambo ehlanganisiwe yaqala ukuminyanisa imakethe yokusetshenziswa yasekuqaleni yochungechunge lwe-British Whitworth.
