In combination with melt spinning means comprising a melt spinning head arranged for extruding vertically downwardly a plurality of molten streams of a thermoplastic and a bath arranged to receive the streams from the head and to contain a liquid to quench and thereby solidify the streams to form filaments, the improvement comprising annular baffle means suspended in the bath in a position to surround the plurality of molten streams or filaments as they move substantially vertically downwardly, the baffle means comprising a plurality of radially spaced concentric annular foraminous members each having its upper edge no lower than the surface of the liquid and the lower edge of each respective member extending to a distance from the surface of the liquid greater than the corresponding distance for any other of the members of smaller diameter and lesser than the corresponding distance for any other of the members of greater diameter.
