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.

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.

A propeller shaft comprising a shaft main body and a yoke which is mounted to the shaft main body with a serrated inserting portion thereof being press fitted into an inner circumferential surface of the shaft main body is constructed such that serration fit-in grooves having extending portions into which serration teeth travel when the yoke is allowed to sink into the shaft main body are formed in advance in the inner circumferential surface of the shaft main body . A method for producing the propeller shaft comprises a yoke press fitting step and a yoke withdrawing step that is to be performed after the former step.

A filament winding apparatus winds yarn impregnated with resin around the surface of a mandrel with a guide member that moves back and forth axially. Yarn winding is initiated while an end of the yarn is held by a holding device provided in a relatively rotatable manner on a rotary shaft. After winding is started, the yarn extending from the mandrel to the holding device is cut. When winding is finished, the yarn is held with the holding device and the yarn is cut between the mandrel and the holding device with a yarn cutting device.

Filament winding apparatus and yarn end processing method for the apparatus

An apparatus for winding a thread around a surface of an object while rotating the object. The apparatus includes a plurality of guide members. The guide members selectively guide a plurality of threads to the surface of the object. One guide member corresponds to one thread. The guide members move along the object. A moving device moves a selected one of the guide members.

Thread winding apparatus

A fiber-reinforced plastic pipe has a joint section formed in one end. The joint section is coupled to another member. The pipe includes a helical layer formed with a fiber. The fiber is wound at a winding angle that is equal to or less than forty-five degrees. The fiber volume fraction of the joint section is lower than the fiber volume fraction of the remainder of the pipe.

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.
