Abstract

1,105,064. Melt-spinning apparatus. FIBER INDUSTRIES Inc. 29 Sept., 1965 [5 Oct., 1964]; No. 41321/65. Heading B5B. A melt spinning assembly has outer and inner rings 11 and 9 respectively with a top cover 8, which together form the body of the melt spinning pack which contains an annulus pierced by spinning orifices 10. A granular filtering medium 12 is retained in place by wire gauze annuli. Channels 20 are provided between an annular bridge plate 13 and projecting into the inner wire gauze 14, while the cylindrical walls of the outer gauze 15 are corrugated to provide inlet channels for the molten polymer. The melt enters the spinning assembly at inlet 17 and enters channel 21 through pipe. 16. After channel 21 is filled with the melt, the corrugations in gauze 15 fill and the molten polymer then percolates through the filter, in the direction of the horizontal arrows, and then flows down the channels formed by bridge plate 13 and inner gauze 14 to orifices 10. The assembly is mainly heated from an outer source, not shown, but additionally, an inner heating unit 19 is provided to ensure a more uniform distribution of heat. As shown, an inner void space 18 may be provided which makes the inner ring of extruded threads accessible through the centre of the assembly. The apparatus of the invention is particularly suitable for melt spinning polymers which are highly viscous, e.g. polyethylene terephthalate, nylon or polyolefins. The granular filtering medium is preferably silica sand, but may be any conventional material, e.g. steel balls, iron filings, stainless steel filings or glass beads.
