ABSTRACT:
A melt spinning apparatus is disclosed for extruding and spinning a thermoplastic melt, and which is adapted to accommodate high melt pressures. The apparatus includes a melt supply head having melt supply duct means extending therethrough, with the melt supply duct means including a plurality of separate duct chambers connected in parallel, and with each duct chamber mounting a filter. The outlets of the duct chambers communicate with a cavity located on the upstream side of a spin plate, and such that the melt passes through the filters and then through the spin plate. The presence of the several filtering duct chambers permits the area upstream of the filters and which is exposed to the high pressure melt to be minimized, to thereby minimize the axial forces operative on the components of the spinning head by reason of the melt pressure.
