A traversing device for stabilizing the yarn path of a thin and uniform flat fiber bundle without causing any trouble, e.g. entanglement of single fibers, and ensuring a good winding appearance of the winding package of fiber bundle, and a yarn path guide for stabilizing the yarn path without causing any trouble, e.g. entanglement of single fibers.

Yarn path guide, traversing device of fiber bundle and system for producing fiber bundle package

An apparatus and method for producing a spread fiber bundle using a fiber-spreading device composed of a group of rollers and a base body reciprocated to be repetitively brought into contact with and kept away from a running fiber bundle, and a method for producing a prepreg. Fiber bundle can be stably and efficiently spread even in the case where the fiber bundle to be spread are filaments having a high elastic modulus such as carbon filaments or where the carbon fiber bundle conveying speed is higher.
