  • Method of assembling filaments and bundle of filaments obtained by the method
    Patent number: 8511054
    Abstract: Disclosed are a method of folding multiple filaments and a bundle of filament produced by the same. More particularly, the method of folding multiple filaments includes release-winding the filaments under a uniform release-winding tension, folding the released filaments in non-twisted states and winding the folded filaments to produce a bundle of filament, so as to effectively prevent some of the filaments in the bundle of filament from hanging down or becoming loose due to different tensions when the bundle of filament is release-wound for post processing. The bundle of filaments includes a plurality of filaments combined together in a non-twisted manner and has highly uniform weight of the filaments per unit length of the bundle of filament, wherein the standard deviation of the weight of each filament ranges from 0.0001 to 0.01 from their average weight.
    Type: Grant

    Date of Patent: August 20, 2013
    Assignee: Kolon Industries, Inc.
    Inventors: Chang-Bae Lee, Tae-Hak Park, Il Nam
