An inert gas is introduced into the polyester melt and distributed uniformly in the melt immediately after its discharge from the polycondensation reactor, 0.05 to 1.0 wt % of an amide compound with a low volatility is added to the polyester melt directly next to the gas inlet. Finally, the polyester melt is subjected to a vacuum degassing immediately before the shaping apparatus and the melt is sent directly to the shaping apparatus within a maximum of 30 minutes after its discharge from the reactor at a maximum temperature of 35.degree. C. above the crystallite melting point of the polyester.
