  • Patent number: 11548241
    Abstract: According to one implementation, a fiber width adjustment device includes: a feeder and an adjuster. The feeder feeds a tape material in a length direction of the tape material. The tape material consists of fibers for a fiber reinforced resin after or before the fibers are impregnated with a resin. The adjuster has a path for the tape material. The path is formed by at least a bottom and a pair of wall surfaces. The interval of the wall surfaces decreased gradually. The width of the tape material which passed the path is changed by adjusting a part of the path. The tape material passes through the part of the path while contacting with the bottom and the wall surfaces.

  • Publication number: 20220266546
    Abstract: A method and apparatus for manufacturing a formed article of a composite material. The formed article is manufactured by heating and pressurizing a thermoplastic resin material and fabric material. The method includes a preforming process in which the material to be formed is put in a preforming mold with a release sheet arranged between the material and a part of the preforming mold. The material is heated and pressurized to impregnate the thermoplastic resin material into the fabric material, thus forming an impregnated intermediate material. Then, in a transport process the impregnated intermediate material in a heated state is taken out from the preforming mold with the release sheet left attached thereto, and transported. Finally there is a forming process in which the impregnated intermediate material is accommodated in the forming mold and the impregnated intermediate material is formed into the formed article of the composite material by pressurizing.

  • Patent number: 10525515
    Abstract: A method for deriving the position of a pushing roll, applied even when there is a difference between the actual processed shape and a theoretical solution (a numerical analysis solution) due to changes in a state of a processing machine or the bending characteristic of the material to be processed. The rolls have a pyramid-like shape, and the operation amount of a pushing roll is changed while continuously feeding a material, thereby bending the material. Also, for each position of the fixed pushing roll, the radius of curvature of the material is measured and the bending characteristic is grasped in advance. From the design shape, the radius of curvature and the operation amount for bringing the pushing roll into contact are obtained. The operation amount of the pushing roll is then determined.
