PROBLEM TO BE SOLVED: To provide a method for the direct spinning and drawing of a polyester yarn keeping the surface of a take-up roller and a drawing roller in a state scarcely influenced by an oiling agent even after the operation over a long period, free from abrasion of the roller surface after the use over a long period and giving a fully drawn yarn(FDY) having good level-dyeing property and extremely low rate of yarn breakage and fluff generation. SOLUTION: A polyester yarn Y melt-spun through a spinneret 1 and oiled with an oiling device 4 is wound 0.5-2.5 turns around non-heated take-up rollers 6a, 6b rotating at a take-up speed of >=4,500 m/min, wound 3.5-6.5 turns around ceramic-coated hot drawing rollers 7a, 7b and drawn 1.1-1.5 times between the take-up rollers and the drawing rollers.
