  • Patent number: 5379500
    Abstract: The invention relates to the production of untwisted yarns from at least two fibril bundles. It gives intermediate method steps, which are so introduced between the main steps of the conventional production method for such yarns (spinning, stretching and texturing), that the reciprocal position of the individual fibril bundles resulting from the arrangement of the spinnerets can be retained through the process. A non-positively acting false twister for each individual fibril bundle, whose strength or thickness can be varied, also makes it possible to reproducibly vary the mixing of the fibrils of the individual bundles in their contact zones.
    Type: Grant
    Filed: September 2, 1993
    Date of Patent: January 10, 1995
    Assignee: Rieter Machine Works, Ltd.
