  • Publication number: 20080048358
    Abstract: The invention relates to a method and a device for producing Lyocell fibres which are extruded from a cellulose solution of water, cellulose and tertiary amine oxide in a spinning head (25). The cellulose solution is obtained in a number of process steps directly from the cellulose (3, 4) or with the formation of a cellulose suspension. Since the degree of polymerisation decreases in the course of processing the cellulose through to its extrusion in the cellulose solution, with the processing of celluloses with a low degree of polymerisation there is the risk that the endless moulded bodies (2) extruded in the spinning head (25) exhibit defective quality.

  • Patent number: 7318717
    Abstract: A method and apparatus for combining raw fibrous and binding materials in a single mixing step (Step S3), followed by consolidation (Step S5) so as to greatly shorten the overall cycle time to a finished fiber-reinforced composite part. Chopped fibrous materials and binder materials are deposited sequentially onto a belt conveyor (Step S2) so that the materials are successively layered, one on top of each other in a predetermined ratio, and subsequently mixed (Step S3) to achieve uniform dispersion throughout. The mixed materials are then deposited into a rotating mold (Step S4) to further ensure uniform dispersion of fibrous and binder materials. Impregnation of the fibrous materials with the binder material occur in-situ as the uniformly mixed materials are heated and subsequently compacted in the mold (Step S5) to obtain the desired shape of the fiber-reinforced composite part.

  • Patent number: 7097442
    Abstract: An extruder capable of obtaining a treatment volume equal to that of the conventional art without enlarging a screw diameter is provided. The extruder includes screw shafts, a drive unit, and a barrel, in which three or more screw shafts having the same diameter and the same root diameter in a waveform shape are engaged with each other and arranged in parallel to each other horizontally or nearly horizontally, while a distance between axial centers is made equal. According to the above configuration, the same treatment volume as that of a conventional extruder can be handled by screw shafts of smaller diameter as compared with that of the conventional art. By using the screw shafts of the smaller diameter as compared with the conventional art, temperature irregularities of an extrusion material in screw grooves, leakage of the extrusion material from the screw shafts, an installation area of the extruder, and the like conventional trouble of various kinds can be eliminated.
