Thickness direction thread insertion needles (11) each include a proximal end portion (12) and an insertion portion (13), which is formed thinner than the proximal end portion (12) and is selectively inserted in laminated fiber layers (23). The insertion portion (13) includes a distal end and a needle's eye formed close to the distal end. A coating (15) is formed on the insertion portion (13). The coating (16) has a surface roughness of 0.1 μm or more and 0.7 μm or less in terms of the center line average roughness Ra, and improves the wear resistance of the insertion portion (13). The thickness direction thread insertion needles (11) are used in producing a three-dimensional fibrous structure. The three dimensional fibrous structure includes the laminated fiber layers (23) formed by laminating fiber layers to be at least biaxially oriented, and thickness direction threads (P) inserted in a direction to intersect the fiber layers to connect the laminated fiber layers (23)

48 Method and means for textile manufacture US10220811 2002-12-16 US20030116218A1 2003-06-26 Nandan Khokar
A method and means for simultaneously inserting weft/binding yarns (45) and their beating-up, in textile manufacturing processes like 3D-weaving and uniaxial noobing, is disclosed. A yarn carrier (90; 39; 22) is equipped with a beating-up reed dent (27; 28). In carrier (90), which comprises a cartridge-like yarn supplying means (1x), the yarn (45) is arranged around two axes of rotation (X1 and X2) and it is enclosed in a case. It is particularly suitable for 3D textile-forming processes like 3D-weaving and uniaxial noobing because of its relatively low-height but high-width and hence the possibility of carrying relatively large amount of yarn. The yarn (45) is contained on a flanged belt (15) that can be driven either from within or from outside of the means (1x). Such a cartridge-like yam supplying means (1x) is equipped with tips (18a, 18b) that are offset or displaced oppositely about the central axis. Such a displaced arrangement of the tips directs the carriers (90; 22) to lay yarn (45) in two different paths, relative to a layer of warp/axial yarns, while traversing back and forth in the same linear path. Through such a method the 3D-weaving and uniaxial noobing processes can be made efficient. The yarn supplying means (1x) could also be useful in other textile processes.

52 Woven 3D fabric material US09380489 1999-09-03 US06338367B1 2002-01-15 Nandan Khokar
A woven 3D fabric material comprises multilayer axial warp yarns and two orthogonal sets of weft which interlace with the rows and the columns of the warp respectively to provide integrity to the fabric which may additionally incorporate between the rows and the columns of the interlacing warp sets of non-interlacing multi-directionally orientated yarns in the fabric-length, -width, -thickness, and two diagonal directions respectively to improve the fabric's mechanical properties. The interlacing of the multilayer warp and the two orthogonal sets of weft is enabled by a dual-directional shedding means which forms sheds in the row-wise and the column wise directions of the multilayer warp. The produced woven 3D fabric material which may be cut into any desired shape without the risk of splitting up, may be wholly or in parts in technical applications.
53 Apparatus for inserting connection yarn into three-dimensional fabric US09533839 2000-03-23 US06267149B1 2001-07-31 Yoshiharu Yasui; Junji Takeuchi; Fujio Hori; Masaaki Amano
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.

In a method of and machine for forming a non-woven bias yarn assembly comprising two superposed non-woven bias yarn sub-assemblies each yarn is transferred by a yarn transfer member from an opening it occupies in a yarn guide member to another opening in the yarn guide member in such a manner that each yarn is caused in a succession of forward transfer steps to follow the yarn preceding it from one opening to another along a non-intersecting path until the yarn at a first end opening in the path arrives at a second end opening in the path located at the opposite end of the path and the yarn at the second end opening in the path arrives at the first end opening and then in a succession of return transfer steps to follow the yarn preceding it from one opening to another along the non-intersecting path in the opposite direction until the yarn from the second end opening in the path arrives at the first end opening and the yarn from the first end opening arrives at the second end opening. The forward and return transfer steps are then successively repeated. A three dimensional yarn structure is also disclosed comprising a non-woven first yarn assembly which has a first face and an opposite second face and which comprises two or more superposed non-woven warp yarn sub-assemblies in which the warp yarns of one sub-assembly are inclined to the warp yarns of the other sub-assembly and in both of which the warp yarns are inclined to a reference warp feed direction.

A process for weaving using a reed having vertically aligned upper and lower reed portions with the reed portions being relatively movable in a weft direction. The process includes transferring warp yarns between the reed portions, moving the transferred warp yarns in the weft direction to define a selected array of warp yarns, and then shedding the array of warp yarns for insertion of weft yarn. A weaving loom head is also provided including a reed having vertically aligned upper and lower reed portions, a plurality of healds each releasably engagable with an individual warp yarn for moving selected warp yarns from one reed portion to the other, and a selectively operable drive mechanism for causing relative movement between the reed portions by a predetermined spacing in the weft direction. Weaves may accordingly be produced including warp threads extending parallel to and/or inclined to the fabric take-off direction. Inclination of the warp threads may be in a horizontal and/or vertical plane. The warp yarns are woven with weft yarns that may extend in a direction generally perpendicular to the take-off direction and/or may be inclined in horizontal and/or vertical plane. Also, complex weaves may be produced wherein the weave pattern can be selectively changed as the weaving process progresses.
