A braided structure forming method suitable for forming a braided structure of a complicated structure capable of serving as the core of FRP and FRTP, in which a speed of pulling up or down a braided structure is varied in process with time to vary the structural density thereof.

Braided structure forming method

Multi-layer tubular braided structures are produced by apparatus including a plurality of generally concentric pairs of serpentine, intersecting bobbin carrier-guiding tracks. A bobbin carrier driving gear group is associated with each pair of tracks, adjacent gear groups meshing at a plurality of bobbin carrier crossover points. According to the method, multi-layer tubular braided structures are produced by circulating a first group of bobbin carriers exclusively along one track of a first pair of tracks, circulating a second group of bobbin carriers exclusively along one track of a second pair of tracks, and circulating at least one other group of bobbin carriers exclusively along at least portions of the other tracks of said pairs of tracks via the crossover points.

Braided structure forming apparatus

A braiding method comprising moving bobbin carriers along tracks connecting a plurality of braiding regions to braid cords or strands in a specific braiding region, in another braiding region or in all the braiding regions. The braid may be used as core structure for fiber-reinforced plastics.

Braid and braiding method

The apparatus comprises a tubular braid machine, a mandrel having branched portions, a holding body for the mandrel capable of effecting upward movement, downward movement, horizontal movement about a braiding point or rotation within a vertical surface, an annular guide detachably mounted at a braiding position to a mandrel main portion, an annular guide detachably mounted at a braiding position to a mandrel branch portion, and a closeable annular guide detachably mounted therebelow.

A sliver can which facilitates the location of a trailing end portion of the sliver. The sliver can includes a main body and a tubular member associated with the main body for receiving an end portion of the sliver. By positioning the end portion of the sliver in a specific area, i.e. the within tubular member, the end portion may be easily located.

A weft breaks monitoring system in a loom which examines the trend of the weft break, and comprises a device for measuring a winding diameter of a weft feed package and a tension meter for detecting a weft break, wherein the winding diameter is divided into plural sections and the number of times of weft break detections from the tension meter is counted every section. A yarn release device for the weft feed package which provides an adequate tension in response to a variation of a release tension resulting from a change in the winding diameter is also provided.

A sliver piecing device includes a pair of holding members for piling and holding ends of slivers to be pieced, and a plurality of needles extending through the holding members and being inserted into the slivers to force the fibers into the other sliver and to intertwine the fibers with each other. In a further embodiment of the piecing device, pressurized air may be used, along with the needles, to force the fibers of one sliver into the other and to intertwine the fibers with each other.

A system for controlling a machine at a remote place is constituted such that, when repairs and a change of a mechanical part of an apparatus on the remote place side are performed and changing of a program for a programmable sequencers for driving and controlling the apparatus is performed, contents of a change of the program thus performed are sent to a computer on the main office side and checked and changed on the main office side to make a correct program, and the correct program is sent to the controlling device on the remote place side.

System for modifying a machine's program at a remote location

A yarn splicing system for splicing a warp in a loom wherein a yarn splicing apparatus is provided with apparatus for searching for a yarn end on the warp beam side of a cut warp. The yarn splicing apparatus may also include a liquid tank for removing size of a sized yarn and a pneumatic yarn splicing device for splicing the yarn end with one end of an additional yarn.
