  • Patent number: 8312907
    Abstract: A fiber bundle arranging device is provided that laminates fiber bundle layers formed of a fiber bundle. The fiber bundle is engaged with arranged pins to have straight parts. The device includes a press roller and a first moving device. The press roller includes a peripheral portion. The peripheral portion of the press roller depresses the straight parts of the fiber bundle engaged with the pins toward the roots of the pins in the vicinity of the pin. The first moving device moves the press roller in the arrangement direction of the pins such that the peripheral portion sequentially intersects the straight parts of the fiber bundle.

  • Patent number: 6742560
    Abstract: Two flat fiber bundles of non-twisted filaments are arranged in an overlapped relationship or in a parallel and adjoining relationship, and held by a gripper at two points spaced apart from each other in the filament-extending direction. Compressed air is injected from a nozzle to the overlapped portion of the fiber bundles between the holding points at a plurality of positions arranged in the direction transverse to the filament-extending direction to cause the adjacent filaments to be entangled. The nozzle is moved across the fiber bundles while injecting air. Filaments are thus opened and rotated by the injected air, and thus entangled. A fiber bundle joining apparatus includes support sections and a receiving section provided in a base, a gripper cooperating with the support sections to grip overlapped ends of fiber bundles therebetween, a nozzle, and a regulating member to temporarily hold the fiber bundles and to allow the lower fiber bundle to be slackened.

  • Publication number: 20020041790
    Abstract: A step portion is provided between a serration portion of a metal-made yoke and a leading end portion thereof. During pressure insertion and joining, an FRP-made cylinder is pressure-inserted to the serration portion in a state that the circularity is enhanced by the step portion. Consequently, the pressure insertion and joining is carried out while making the depth of cut grooves uniform, thereby enhancing concentricity (joining accuracy).

  • Patent number: 6267149
    Abstract: A connection yarn inserting apparatus for manufacturing three-dimensional fabric. The apparatus inserts connection yarns into a lamination of fiber layers in a direction transverse to each fiber layer. The apparatus has insertion needles for inserting connection yarns into the lamination. The insertion needles are moved between a standby position, where the needles are separated from the lamination, and an operational position, where the needles penetrate the lamination. The lamination is clamped by a pair of opposed pressing members. The pressing members are operated by air cylinders. A stopper can be moved into and away from the moving range of the piston rod of each of the air cylinders. The stopper is actuated by an actuator. When the stoppers in the moving range of the associated piston rod, the stopper limits the stroke of the piston rod. This reduces the time necessary to move the associated piston rod and increases productivity.

  • Patent number: 5833802
    Abstract: An apparatus for production of a three-dimensional fabric including laminated fiber layers having a fiber arranged along axial lines and a connection yarn inserted into the fiber layers to connect the fiber layers with each other are described. The fiber layers are formed by arranging the fiber while folding the fiber back along the axial lines. The laminated fiber layers are formed by arranging the fiber along axial lines, by engaging the fiber to a plurality of restriction members located with a predetermined pitch on a frame so as to surround an area where the connection fiber is inserted into the fiber layers, and then folding the fiber back along the axial lines. A plurality of yarn inserting needles arranged in a series together with the connection fiber are simultaneously thrust into the fiber layers until a holding section of each yarn inserting needle projects outside of the fiber layers to make a loop of the connection yarn at each holding section.

  • Patent number: 5327621
    Abstract: A reinforcing matrix is produced using a plurality of regulating members (pins) removably arranged in rows in a predetermined direction on a base. Yarns are woven between the pins on the base repeatedly looping back and forth between spaced apart positions to form a yarn lamination consisting of a plurality of yarn layers over the base. The yarns forming the yarn layers are arranged in at least two directions. Thereafter the yarn lamination is removed from the base together with the pins. Then the pins are replaced sequentially in rows arranged in the predetermined direction with separate vertical yarns which are inserted into the yarn lamination so as to form loops. A selvage thread is inserted in the predetermined direction through the loops of the vertical yarns.
