  • Melt spinning of synthetic yarns
    Patent number: 4283364
    Abstract: An apparatus for melt spinning of polymers into synthetic yarns having greater bundle uniformity has a spinning assembly for extruding molten polymers through orifices in a spinning plate to form filaments and a blow box for directing cooling gas transversely across and through the filaments that extend vertically downwardly from the spinning plates. The spinning plate is provided with at least two groups of orifices and the groups are arranged to provide one or more open lanes or channels that extend across the plate in a direction parallel to the direction of flow of the cooling gas. This lane has a width greater than the distance between adjacent orifices.
