A method and apparatus for producing a multifilament yarn by a melt spinning-draw process, and which includes applying additional heat to the melt in the region of the spinneret. The relationship between the withdrawal speed and draw ratio may be changed, and with an adaptation of other process parameters, it is possible to increase productivity. The process may be applied to continuous and discontinuous processes.
