摘要 |
Apparatus and process for thermal treatment of thermoplastic polymer multifile filaments embodying at least one stuffing chamber for forming at least one multifile filament into at least one tightly coherently packed filamentary body, feeding one or more of said filamentary bodies onto gas-permeable, slowly rotating drum on which it or they are conveyed in a side-by-side, spiral orientation by the rotating drum while a fluid, e.g., air is drawn through the filamentary bodies, said filamentary bodies being conveyed from the stuffing chamber at a constant rate and being deflected at a predetermined pitch angle before or during initial contact with the drum surface.
