Abstract
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.
