Melt spinning of synthetic yarns

A process for melt spinning of polymers into synthetic yarns with a spinneret assembly including a spinning plate which comprises extruding a molten polymer downwardly through a spinning plate having a plurality of spinning orifices to form filaments of said polymer that extend vertically downwardly from said plate, arranging said filaments into a plurality of groups by providing the spinning plate with at least one open lane that is free of orifices and that extends across the operative area of the plate between the groups of orifices corresponding to the groups of filaments, said orifices being arranged in parallel rows in each group and said lane having a width wider than the distance between adjacent orifices within each of said groups, with the spinning plate having an average of from 2 to 10 orifices per (10 mm.).sup.2 of the operative area, and passing a cooling gas transversely between and through the groups of filaments in a direction parallel to a centerline of the lane whereby said filaments provide a yarn of a high filament count and of a low denier per filament count that exhibits a reduced degree of denier uneveness as compared with a yarn with the same filament count and denier produced by a conventional spinning plate having the same operative area.
