摘要：Provided are a method for manufacturing and a device for manufacturing apartial split-fiber fiber bundle and a partial split-fiber fiber bundle obtained using thesemethod and device, said method being characterized by piercing a fiber splitting meansprovided with a plurality of protruding parts into a fiber bundle formed from a pluralityof single fibers while making the fiber bundle travel along the longitudinal directionthereof and creating a split-fiber processed part, forming entangled parts where singlefibers are interlaced at contact parts with the protruding parts in at least one split-fiberprocessed part, thereafter pulling the fiber splitting means out of the fiber bundle, andafter passing through an entanglement accumulation part including the entangled parts,once again piercing the fiber splitting means into the fiber bundle. Thus, the presentinvention can provide a method for manufacturing and a manufacturing device for apartial split-fiber fiber bundle that can continuously and stably slit a fiber bundle.Specifically, the present invention can provide a method for manufacturing and a

manufacturing device for a partial split-fiber fiber bundle that make continuous slitprocessing possible without having to worry about the exchange life of rotary bladeseven if the fiber bundle includes twists or the fiber bundle is a large tow having a largenumber of single fibers, as well as a partial split-fiber fiber bundle obtained using thesemethod for manufacturing and manufacturing device.
