Abstract: PROBLEM TO BE SOLVED: To prevent the generation of dust and noise by forming a regular uneven surface at least on one side, to reduce an apparatus expense, and to obviate running costs. SOLUTION: Fiber bundles impregnated with a resin to be thread-supplied continuously are introduced into a molding die 6, and a desired lengthy molding 4 is molded. It is sent to an uneven surface giving apparatus 1 while being softened and introduced between a transfer roll 2 and a support roll 3. The transfer roll 2 is pressed to the support roll 3, and a shape formed on the roll is transferred on one surface of the molding 4 to produce a lengthy molding 5 having an uneven surface. In this process, by the thickness of the molding 4, the kind of a resin to be used or the ratio of the resin to the fiber bundles, a traveling speed, and others, the distance between the apparatus 1 and the outlet side end surface of the molding die 6 is decided appropriately. In this way, uneven working formed on the peripheral surface of the roll is transferred completely to the molding 4, and surface roughness in the aimed direction can be produced easily and stably under a good environment.

Abstract: PROBLEM TO BE SOLVED: To produce a material for a box of an electric or electronic equipment or the like by opening a fiber bundle in the radial direction with a weak tensile strength into a thin homogenous state by hitting gas, which has been suctioned from a gas flow suctioning part, on the fiber bundle in the direction crossing the running direction and suctioning the opposite side of the gas flow suctioning part. SOLUTION: Laminar gas which has been suctioned from a gas flow suctioning part is hit on a continuously fed fiber bundle 30 of carbon fiber, aramid fiber or the like in the direction crossing the running direction V of the fiber bundle, and the opposite side of the gas flow suctioning part is suctioned. Thus, the fiber bundle 30 is opened in the lateral direction. Further, it is preferred that the fiber bundle 30 is heated or preliminarily opened before it is introduced into the cylindrical part of an air duct 2.
