ABSTRACT:
An apparatus for spinning filaments from a melt has a nozzle plate with a plurality of passages through which the melt flows to form a stream of filaments, a downstream dispersing head in the stream in the form of a cylinder with its axis parallel to the stream of filaments and having an upstream end and a downstream end, a coolant source connected to the dispersing head having a porous wall parallel to the filament stream whereby coolant passes through the wall and impinges on the filaments and a baffle in the dispersing head to reduce the coolant pressure adjacent to the baffle, a resistance to the coolant flow satisfying a specific formula which avoids the prior art problems.
