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. The peripheral portion is located in the front of the press roller in the moving direction, and the press roller is moved to sequentially intersect the straight parts of the fiber bundle while being inclined such that, toward the front end in the moving direction of the press roller, the distance from the roots of the pins in the laminating direction of the fiber bundle layers increases.

A cylindermade of a magnetic material is fixed to an introduction pipe. An annular connection projectionis provided on the cylinderand a diskis connected to the connection projectionwith an annular permanent magnet. The permanent magnetis fixed to the diskand connected to a distal end surface of the connection projectionby a magnetic force. A guide pipeis fixed to the disk. The guide pipeand the introduction pipeare connected to each other in series by a connection portionhaving the cylinder, the permanent magnet, and the disk. A fiber bundle F that is guided via a guide rolleris fed to an introduction holeand a guide hole

Fiber bundle arranging apparatus

A connection pipeA is fit in an introduction pipeA. A guide grooveextends on the side of the introduction pipeA in the Z-axis direction. A guide screwis screwed on the peripheral face of the connection pipeA to penetrate through a peripheral wall of the connection pipeA. A distal end of the guide screwenters the guide groove. The distal end of the guide screwis movable in the Z-axis direction in the guide groove. The connection pipeA is movable relative to the introduction pipeA in the Z-axis direction within the range of the length of the guide groove. The connection pipeA and the guide pipesA are moved in the Z-axis direction with an air cylinder. Accordingly, when fiber bundles are arranged using a plurality of guide pipes, the guide pipe is prevented from being caught by a fiber bundle drawn out of another guide pipe.

Apparatus for arranging fiber bundles

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.

Method and apparatus for manufacturing fiber bundle with injected air

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.

Apparatus for inserting connection yarn into three-dimensional fabric

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. A lock yarn is inserted into each loop along a direction where the yarn inserting needles are arranged. The lock yarn is tightened by pulling back the yarn inserting needles while pressing members press the fiber layers from opposing sides of the fiber layers near the yarn inserting needles after the lock yarn is inserted into each loop. The fiber layers are removed from the frame after the inserting of the connection yarn is terminated.

Method and apparatus for production of a three-dimensional fabric

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.
