<PICT:0755954/IV(a)/1> In a spinning pack for melt-spinning, joints between the components of the pack are so arranged that the hydraulic pressure of the melt acts to seal all of such joints. As shown, the spinning pack comprises a cylindrical container 1 having a flange 2 on which rests a gasket 3, spinneret 4, bridge plate 5, distribution plate 7, gauzes 10 and sand pack 11. A distributer plate 12 is attached by legs (not shown) to lid 13 which rests on flange 14 and which is sealed by gasket 15 and threaded lock ring 16. The melt is pumped in at 17 and the pressure exerted thereby lifts the lid 13 against gasket 15 and presses down the rest of the assembly against gasket 3. |
