ABSTRACT:
A melt spinning apparatus is disclosed which includes a supporting housing, a melt supply block mounted in the upper end of the housing, and a spin plate mounted adjacent the lower end of the housing so as to define a spinning chamber between the block and plate. A melt diverting plate is positioned in the spinning chamber for deflecting the melt entering into the chamber, and the melt diverting plate is configured such that substantially the same pressure drop occurs in the melt as it moves from the melt supply duct to all portions of the upper surface of the spin plate, so as to achieve a substantially uniform denier among the resulting filaments.
