Abstract

PURPOSE: To mechanically and efficiently form a handwoven brocade pattern woven fabric by making guide members for ground warp yarns and pattern weft yarns perform reciprocating motion in a specific direction, alternately forming a closed gap and an opened gap and picking a linear weft yarn in the weaving width direction in the closed gap. CONSTITUTION: An opened gap is formed from ground warp yarns (a) and (b) respectively guided with guide members 10 and 16 for warp yarns and the guide member 10 for the warp yarns and a guide member group 20 for pattern weft yarns and the guide member 16 for the warp yarns and a guide member group 22 for the pattern weft yarns are oppositely moved to form a closed gap crossed in an X-shaped state. A rapier band 15 is passed through the closed gap X to pass the linear weft yarns through the weaving width direction and carry out the picking. The above guide members 10 and 16 and the guide member groups 20 and 22 are moved in the direction of arrows to form an opened gap again. The weaving process is repeated to thereby mechanically and efficiently weave a handwoven brocade.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for weaving a fabric, and particularly to a method for weaving a tapestry pattern fabric.

[Prior Art] Conventionally, there is a so-called tapestry weaving in which a patterned fabric is formed by weaving multiple types of weft yarns into the ground warp at different widths for each step according to a sketch, but when weaving this tapestry, Since it is necessary to weave the weft threads partially into multiple shelves, it is not possible to drive the weft threads uniformly with a reed as in the case of a power loom, and it is also not possible to insert the weft threads partially into the machine. Because it was difficult to weave, it was usually woven by hand.

[Problems to be Solved by the Invention] The present inventor has devised a loom that is capable of partially folding and inserting multiple types of weft yarns in the weave width direction, such as the above-mentioned tapestry weave, and that is also capable of mechanically weaving. As a result of intensive research into a method for weaving a tapered pattern fabric using a loom, it was made possible by using a loom that opens the warp threads using a new method instead of using conventional heddles.

[Means for Solving the Problems] The present invention provides a weaving method for the above-mentioned tapered patterned fabric, in which a plurality of guide members each having yarn guiding pieces for guiding the ground warp and pattern weft are arranged in parallel, and at least the pattern weft is A guide member for guiding the weft threads is slidable in the weaving width direction, and a straight line between the open ground warp threads is formed by relative opposing movement between at least one row of guide members and other guide members. Using a loom that has a device for penetrating the weft threads, a guide member that guides the pattern wefts is moved in the weaving width direction in accordance with the pattern configuration inside the open gap formed by the ground warp threads, and then the pattern weft threads are formed by the ground warp threads. A linear weft is passed through the closed gap, and an open gap is again formed by the ground warp, and inside the gap, the guide member for the pattern weft is moved in the weaving width direction in accordance with the pattern configuration. By repeating the above weaving process, a patterned fabric in which the pattern weft is woven into the ground warp is woven.

[Function] In the weaving method according to the present invention, the guide member that guides the pattern weft is moved by an arbitrary warp pitch inside the gap formed between the ground warp threads by moving the guide members in opposite directions. Therefore, these pattern wefts were woven in a tapestry pattern to the ground weft created by the ground warp.

[Example] Next, the weaving method of the present invention will be explained in detail based on the drawings.

1 to 3 are side views of essential weaving parts showing the weaving process of the weaving method of the present invention step by step. FIG. 4 shows the entire loom used for this weaving.

Reference numeral 10 denotes a guide member for guiding the ground warp yarns a, which is supported by a hanger 12 supported by a support shaft 14a, and extends in a long shape in the weaving width direction, that is, in a direction perpendicular to the plane of the paper. It is slidably provided. 1G is a guide member for guiding the ground warp threads, and the support shaft 1
It is supported by a hanger 18 supported by the guide member 4b, and is provided so as to be slidable in the weaving width direction in the same manner as the guide member IO.

20 is a guide member group on one side that guides the pattern weft C;
Inside the guide member 10, that is, on the left side in the figure,
Similarly, it is supported by a hanger 12 so as to be slidable in the weaving width force direction. 22 is a guide member group on the other side that guides the pattern weft d, and the hanger 18 is located inside the guide member 16.
It is supported so as to be slidable in the weaving width direction. The above-mentioned warp guide member 10.16 and pattern weft guide member group 20.2
2 performs a relative counter-reciprocating motion, which is done as follows. Reference numerals 24 and 26 indicate camshafts arranged in parallel in the front and rear, and are rotated by a drive motor (not shown). 28, 30, 32.34 are two cams arranged on the left and right sides of these cam shafts (30 is behind 28).
but there is also 34 behind 32), through cam levers 38, 38, 40, 42 (38 behind 36 and 42 behind 40) engaging the respective cams, respectively. The rods 44, 4B, 48.50 drive levers 52.54.78.58. The motion given to the hanger 12 by the rod 46 via the lever 54 is a swinging motion about the support shaft 14a. This movement is caused by the gear 60 fitted on the support shaft 14a, the gear 62 meshed with this gear, and the gear 62 at V! ;,'
4 is transmitted to the hanger 18 via the supporting shaft 14b. As a result, hanger 12 and hanger 18
swing in opposite directions, and the guide member 10 and the guide member group 20, and the guide member 16 and the guide member group 22 mounted thereon, perform opposing swing motions. As shown in Fig. 1, when the guide member 10.20 and the guide member 16.22 are separated from each other, an open gap Y is formed by the warp threads a, C and the warp threads d, as shown in Fig. 2. When the two intersect in an X-shape, a closed gap X is formed. F is a woven fabric, and winding roller e4. From ee,
After passing through rollers 88, 70, 72, it is wound up by winding means (not shown). A reed 74 is attached to the tip of the lever 58, and a large number of blades 76 are implanted in the reed 74 in a direction perpendicular to the plane of the paper in a number corresponding to the number of warp threads. rotational movement,
Due to the compound movement of the lever 58 around the support shaft 82 given by the vertical movement of the rod 50,
The reed 74 performs a circular movement as shown in C. Also, 84
is a guide bar of the rapier device, and this guide bar enters and retreats into the weaving section by a rotational movement about the fulcrum 88 of the lever 52 given by the vertical movement of the rod 44, and in the weaving section, We will guide you through the rapier band, which will be described later.

Furthermore, the warp guide member 10.18 and the pattern weft guide member group 20.22 are reciprocated in the weaving width direction, that is, in the direction perpendicular to the plane of the paper, as necessary. It is possible to apply drive means that are For example, as shown in FIG. 5, a shock lever 89 is rotated about a support shaft 90 by a chain piece 88 suspended on a chain drum 87, thereby moving the rod 19 forward and backward. There is a form of communication. In addition, a positioning means using a combination of gauge pieces having a plurality of thicknesses in place of a chain piece, a positioning movement means using a servo motor, etc. can be used.

The above is the configuration of the loom used to carry out the weaving of the present invention.Next, the weaving process will be explained based on the process diagrams in Figures 1 to 3 and the weaving organization chart in Figure 6. do. Although FIG. 1 shows the pattern weft d threaded through the guide member group 22, in the weaving of the structure shown in FIG. 6, the pattern weft d is not threaded.

In FIG. 1, as described above, the warp b is guided by the thread guide piece 17 of the guide member 1G, the pattern weft c, c is guided by the thread guide piece 21.23 in the guide member 20,
and the warp yarn a guided by the yarn guide piece 11 of the guide member 10
forms an open gap Y.

In this case, as shown in the figure, there are other guiding pieces in the pattern weft guiding member group 20 other than 21 and 23, and other pattern wefts are guided by these other guiding pieces. However, for convenience of explanation, only two are shown with reference numerals in the figure.

Assuming that the state shown in FIG. 1 is the state at the start point S in FIG. At the same time, the thread guide piece 23 is also moved to the right by five pitches, and the other thread guide pieces are also moved by the necessary pitches. Next, the guide member 10 and the guide member group 20, and the guide member I6 and the guide member group 22 are moved in opposite directions to each other in the direction of the arrow in FIG. 1, and are crossed in an X shape as shown in FIG. TS2. This forms a closed gap X. The straight weft f is passed through the rapier band 15 of a well-known rapier device (not shown) through the closed gap Penetrate in the weave width direction. Next, the reed 74 is pulled up in the direction of the arrow in FIG. 2, the guide member 10 and the guide member group 20, and the guide member 1B and the guide member group 22 are separated in the direction of the arrow in FIG. reach the position.

At this time, the blade 76 of the reed 74 is
．． It invades between 21 and 23... and moves downward. Therefore, at this time, warp a.

Even if the pattern wefts C and B are close together, the threads can be separated reliably. Next, the reed 74 descends to the position shown by the imaginary line, pushes down the straight weft f, and drives it into the woven end B. Then, the reed 74 retreats to the rear, that is, to the left in the figure, and the guide member 10 and the guide member group 20 and the guide member 1
G and the guide member group 22 each move in the direction of the arrow and reach the position shown in FIG. 1 again, forming an open gap Y, and thereafter repeating the weaving described above. The momentum of the guide member groups 2o and 22 is determined by the driving means for each weaving stage in accordance with the jump pitch of the pattern weft.

Thus, one of the key points of this invention is that the pattern weft is inserted inside the V-shaped gap formed by the ground warp.

In addition, in FIGS. 1 to 4, only two guide members 10.16 for guiding the warp threads are shown for convenience of illustration.
Although shown in the figure, in reality, a large number of guide members to and te are interposed in the guide member group 20.22 that guides the pattern weft. That is, as shown in FIG. 6, there are a large number of warp yarns for the two pattern wefts C and C2, and similarly there are a large number of guide members 10.16 in reality.

FIG. 7 is a weaving structure diagram showing another structure of the patterned fabric woven by the weaving method of the present invention, and this weaving includes the
A loom with the configuration shown in the figure is used.

The one in FIG. 8 shows warp b1 pattern weft c and d guided by guide members 1B and 29.31, respectively, and guide member 10.
The warp threads a are guided by the warp threads a.

The case of weaving the structure shown in FIG. 7 using the above loom will be explained. The warp threads a and warp threads are connected to the guide piece L1. of the guide member 10.16. The threads are threaded into L7 in a general manner. The pattern wefts c and d are passed through the guide piece 25.27 of the guide member 29.31 at intervals corresponding to the width swayed in the weaving width direction. As means for driving the guide members 29 and 31 in the weave width direction,
It is equipped with what is shown in Figure 5. In FIG. 7, 02 pattern wefts and 61 pattern wefts are arranged as pattern wefts. In the figure, when the start position is set as S, the weaving position at this S forms an open gap Y shown in FIG. At this time, the guide members 29, 31 are moved by nine warp pitches to the right in FIG. 7 in the weaving width direction by the driving means. Next, the guide members 1B, 29.31 and the guide member 10 move toward each other in the direction of the arrow in FIG. 8, and as shown in FIG.

Press down to the weaving end B between the two. The guide member further advances and intersects in an X shape, reaching the position shown in Fig. 9, where the straight weft f is inserted across the entire width into the closed gap X by a weft inserting means such as a rapier. . Next, the straight weft f is pushed down to the weaving end B by the reed 74, and the weave of the fabric is tightened. Then, the guide members 1B, 29.31 and the guide member 10
and move each other outwardly to return to the weaving position shown in FIG.
The yarn is swayed by one warp pitch, and the same weaving as the above movement is repeated. Thereafter, the guide members 29 and 31 are alternately moved left and right in the open gap Y so that the pattern wefts c and d are arranged in accordance with the pattern pattern, thereby forming a tapered pattern 1.

In the above embodiment, the two sets of guide members that intersect with each other to form the opening are both similar to the guide bars of a warp knitting machine, but instead of this, one is replaced with a horizontally extending belt. A bar-type guide member (Japanese Patent Application No. 61-204026) may also be used, and in any case, the specific form of the guide member is not limited.

[Effects of the Invention] In the weaving method according to the present invention, the guide member that guides the pattern weft is moved by an arbitrary warp pitch inside the gap formed between the ground warp threads by moving the guide members in opposite directions. By weaving the pattern weft threads in a tapestry pattern into the ground weave, the pattern weft can be mechanically and efficiently woven into the pattern fabric in which the pattern warp threads are woven in a tapestry pattern. can be produced.
