ABSTRACT:
A method of producing a spread multi-filament bundle along with an apparatus used in the same, by which a multi-filament bundle is spread with high speed and facility, and a high quality spread multi-filament bundle or sheet with the component monofilaments thereof aligned in parallel widthwise and uniformly distributed in density is produced. The multi-filament bundle in carriage is subject to fluctuation of a tensile force applied thereto alternatively between tension and relaxation by locally and reciprocally pressing the bundle fed from a yarn supplier crosswise with regard to a moving course of the bundle, and the multi-filament bundle moving under the fluctuation passes in suspension through a fluid flowing portion, and the multi-filament bundle is subject to fluidal resistance while the bundle moving through the fluid flowing portion so as to bend the bundle towards a direction to which a fluid in use flows, and the fluid flows through an interstice between any adjacent monofilaments of the bundle whose bonding is slackened due to the fluidal resistance so as to widen the interstice.
