In the present invention, the supply path of the reciprocating skew yarns (3) and (4) is changed by approximately 90 °, for example, when the swash yarns (3) and (4) are supplied in a substantially vertical direction. , The supply path is changed in a substantially horizontal direction, and conversely, when the swashes (3) and (4) are supplied in a substantially horizontal direction, the supply path is changed in a substantially vertical direction. The angle is not limited to an angle around 90 °, but may be around 100 ° or around 80 °.

<Operation and Example> Hereinafter, the configuration of the present invention will be described in detail together with the operation with reference to the example drawings.

FIG. 1 is a schematic side view of a multi-axis loom of the present invention, and FIG.
The figure is a schematic enlarged side view of a main part. FIG. 3 is a plan view of a guide chain member used for the traverse mechanism of the slant traverse heald device. 4 to 8 are schematic side views each illustrating the mechanism of a multi-axis loom for four-axis woven fabric in a weaving stage. FIG. 9 is an organization diagram showing an example of a four-axis woven fabric woven by the multi-axis loom of the present invention.

The multi-axis loom of the present invention shown in FIG. 1 is a three-axis woven loom, in which a plurality of bobbins or a plurality of divided beams are rotatably arranged in a plane substantially parallel to a traveling direction of a weaving surface. It has an array of screed creels (A). The screed creel (A) has a number of split sliver beams (5), which are rotatably supported on circular rails (12) of a side frame (13). Reference numeral (14) in FIG. 1 is an upper frame. The screed creel (A) rotates in the horizontal plane, and the woven surface advances in the horizontal plane. This point is a major feature of the present invention. In the conventional loom, the rotating surface of the screed creel (A) and the traveling direction of the weaving surface have a substantially right angle.

The slant traverse heald device (B) is composed of a number of forward slant yarns (3) and return slant yarns (4) that continuously circulate in opposite directions at predetermined intervals substantially continuously from the slant creel (A) within the weaving surface. Are supplied crossing each other in opposite inclination directions, and
A diagonal thread traverse mechanism that changes the supply path of the reciprocating diagonal threads (3) and (4) to approximately 90 ° and supplies the reciprocating diagonal threads (3) and (4) to the weaving surface is also provided. A guide chain (16) which has an unconventional structure and is arranged in a two-stage manner as shown in FIGS. 2 and 3.
Numerous needle guide holes (17) provided on the side protrusion of (16)
Each of (17) has a heald guide needle (18) inserted therethrough, and a large number of swashes guided and supported by the guide rolls (7) are inserted into the guide needles (18). As the chains (16) and (16) make round trips,
The structure is such that the yarn is intermittently circulated from the forward slant thread (3) to the backward slant thread (4) and vice versa. The shaft (19) of a two-stage sprocket (15) (15) on which the guide chains (16) (16) are hung is rotatably supported by bearings (20), and this shaft (19) is intermittent. Drive.

Here, the movement of the diagonal heald guide needle (18) is another feature of the present invention. Since the weaving surface is a horizontal surface, the right and left rows of the diagonal heald guide needles (18) are pressed by the diagonal heddle needle holders (21) (21) which reciprocate up and down by cam drive, so that the reciprocating diagonal thread (3) And (4) can be opened. The return rise of the heald guide needle (18) is caused by, for example, the reaction force of the spring (11). As shown in FIG. 1, when any one of the reciprocating weft yarns (3) and (4) is opened, the weft driving device (C) is used to make the weft yarn (2).
Type. As is clear from FIGS. 4, 7, and 8, the supply path is changed from the vertical direction to the horizontal direction by approximately 90 ° from the tip of the diagonal heald guide needle (18), and is turned to the weave surface. The reciprocating skew yarns (3) and (4) sent out are provided at the tip of the skew heald guide needle (18) of the forward swash yarn (3) on the weaving surface side, and the backward slanting position located behind it relative to the weaving surface. The swash thread (4) sent out from the tip of the heddle heald guide needle (18) of the thread (4) is arranged so as not to be caught and circulates smoothly. This is made possible by the interrelationship between the interval between the two sets of slanted heald guide needles (18) and (18) and the angle of inclination when the reciprocating slanted yarns (3) and (4) are supplied to the woven surface.

As the weft driving device (C), the beating device (D), and the product winding device (E), conventionally known devices can be used as they are, and they are sequentially arranged from left to right in the drawing. Since the weft (2) is run by the weft driving device (C), the beating is performed by the reeds (8) and (8) of the reeding device (D), and the product is wound into the product roll (9) by the product winding device (E). is there.

The above description is about a multi-axial loom for a triaxial woven fabric. However, the mechanism of the loom for the triaxial woven fabric includes a warp supply including a diameter-regulated beam (6) for supplying a warp (1) into a weaving surface. The mechanism of the multi-axis loom for the four-axis fabric incorporating the device (F) will be described with reference to FIGS.

As shown in FIG. 4, the warp yarns (1a) and (1b) which are divided and sent out from the diameter-regulated beam (6) provided to send the warp yarn (1) in the same direction as the weaving surface are divided into two series. The warp healds (10a) (10b) divided into a large number of two lines are time-divided and opened by cam drive as shown in FIGS.
It is made into a four-axis fabric in combination with the mechanism for the three-axis fabric described above.

The tissue weaving of the four-axis fabric by the loom for the four-axis fabric is ninth.
As shown in the figure. That is, the forward slant thread (3) in FIG.
, Only the front warp (1a) in FIG. 7, only the backward slant (4) in FIG. FIG. 8 shows a mode in which the yarn is opened once every four rotations in the order of the opening of only the rear warp (1b), in which four kinds of yarns successively weave the weft (2) four times. ing.

Thus, the multi-axis loom of the present invention changes the opening order of the forward warp (3), the backward warp (4), the front warp (1a) and the rear warp (1b) of the split warp (1). By this, it is possible to select the most appropriate opening order to make various structures by thick yarn, thin yarn, mixed weaving of thick yarn and fine yarn, or by the density of driving etc. It is capable of high-speed weaving of triaxial or quadriaxial fabrics of various structures.

<Effect of the Invention> The multi-axial loom of the present invention described in detail above has an excellent effect of being capable of high-speed weaving of a triaxial woven fabric or a four-axial woven fabric, and has a simple structure and can be provided at a low cost. It has features.
