Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative crest woven fabric, for example, which expresses a picture of a landscape, a person, etc. by a woven fabric, and has a value as an interior decoration product. The present invention relates to a method for manufacturing a large-sized pattern fabric.

[0002]

2. Description of the Related Art Generally, a mechanism called a jacquard machine is often used when weaving a complicated pattern fabric of this type. Conventionally, when weaving a pattern with a jacquard machine,
First, a normal picture of the same size as the woven pattern was drawn, a design drawing was created from this normal picture, and a pattern paper was created based on this design drawing. The pattern paper is a cardboard that is bound in a strip shape for guiding a device that raises and lowers the warp according to the organization, and commands up and down movement of the warp depending on whether there is a hole at a predetermined position of the pattern paper and has a hole. By the way, the warp is raised and woven over the weft, and conversely, when there is no hole, it is woven under the weft to form a pattern. Therefore, since one sheet of paper is required each time one weft thread is passed through, tens of thousands of sheets of paper may be required when weaving a single fabric.

In recent years, in order to simplify and speed up the weaving process, the information on the embossing paper is input to a disc using a computer, and the embossing paper information is sent directly from this disc to a direct jacquard machine and automatically. A system that controls the operation of the jacquard mechanism has been constructed and is currently in practical use. On the other hand, the demand for woven fabrics is diversifying, and in addition to the demand as clothing, bedding, furniture decoration, industrial materials, the demand for interior decoration products is increasing. For example, landscapes, people, paintings, etc. are represented by a textured structure, and the woven fabric is attached to a wall, put on the frame, or hung like a wall, and is displayed indoors.

[0004]

For example, if the size of the decorative woven fabric is within the width of the jacquard machine, one weaving pass is performed by the above-described woven paper or the disk drive system instead of the woven paper. With this, the pattern can be woven without any problems.

However, with the expansion of the use of decorative pattern fabrics, the required fabric size may reach several meters to several tens of meters. In this case, it is conceivable to divide the picture to be drawn into each possible weaving range to make a pattern paper or a disc for pattern paper, and weaving it. However, one lot is weaved for each divided design. Then, the manufacturing process becomes complicated, and considerable labor and time are required. In addition, when the edges of the fabric are distorted due to subtle tissue or mechanical errors, and the woven fabric pieces are sewn together or arranged side by side, the boundary lines and diagrams of the patterns do not match. There is. Particularly, in the case of a decorative crest woven fabric, the deviation of the design or the like may significantly reduce the commercial value of itself, which is a manufacturing problem. Therefore, the main problem of the present invention relates to weaving of a large-sized decorative crest fabric, aiming at simplification and speedup of the weaving process, and mutual deviation of the patterns between crest fabrics woven separately. It is intended to provide a manufacturing method that prevents the occurrence.

[0006]

In the manufacturing method for weaving a woven fabric by controlling the jacquard mechanism based on the pattern paper information stored in the disc, one design drawing on the disc memory is parallel lines. In addition to dividing the blocks into strips, the pattern paper information on the disk memory for weaving one pattern fabric is sent to the jacquard machine for each block continuously according to the block division, It can be solved by weaving. In addition, it is desirable that the block division be performed while each adjacent block has an overlap margin.

[0007]

According to the present invention, in accordance with a normal work procedure, for example, a picture read by an image scanner or a picture arbitrarily drawn on a computer is inputted as a design drawing into the disk memory as pattern paper information. To be done. After that, one design drawing on this disc memory is divided into parallel strips into blocks in parallel lines, and according to this block division, the pattern paper information (warp control, Weft command control, etc.) is continuously sent to the jacquard machine for each of the blocks and the pattern cloth is woven.

Therefore, no matter how large the size is, it is possible to continuously and simply weave in one weaving pass. The reason why the blocks are divided in parallel is that weaving in the warp direction is infinite and there is no limitation in size.

In addition, in the present invention, as described above, weaving is performed under the same conditions in one weaving pass, and in order to have an overlap margin between adjacent blocks, stitching is performed between the crest woven fabrics woven for each block. It is possible to eliminate the misalignment of the pictures as much as possible. Further, when it is attached to a wall or put on a frame for decoration, as shown in FIG. 7, pattern cloths 7A and 7B are overlapped so that the patterns match each other, and the middle of the overlapped portion is cut by a cutter 20. By doing so, it is possible to cut so that the patterns fit each other. It should be noted that the block division while giving the overlap margin can be easily performed because it is an operation on the disk.

[0010]

The present invention will be described in detail below with reference to the drawings. First, FIG. 2 is a diagram showing an outline of a weaving process according to the present invention. In a disk drive type pattern information system, a design drawing 1 in which, for example, a landscape or a person is drawn is directly read by an image scanner 2 and this information is displayed on a screen of a computer 3. In the image scantner 2, the colors applied to the design drawing are read in full color, so the colors of the colors are dropped on the computer 3, leaving only the desired number of colors, or changing the colors. In addition, each color number and the organization number used for weaving are made to correspond to each other, and a series of work for converting the pattern paper into information is performed, such as correcting the organization of the boundary portion of each pattern. When these color correction and texture correction are completed, these information are recorded on the floppy disk 5 as pattern paper information. The pattern displayed on the computer 3 is output by the color printer 6 as needed.

On the other hand, the direct jacquard machine 4 is shown in FIG.
As shown in FIG. 3, the switch 10 receives the control signal from the floppy disk 5, turns on the switch 10, and the solenoid coil 11 is energized.
By this energization, the iron core 12 inserted in the solenoid coil 11 is pulled to the left side in the drawing, and at the same time, the horizontal needle 13 connected to this is pulled to the iron core 12 side. The vertical needles 15 are connected to the horizontal needles 13, respectively, and are tilted by the movement of the horizontal needles 13 to be hooked on the knife 14. Threads 17 are connected to the lower ends of the vertical needles 15, respectively, and the thread 17 is inserted while the positions thereof are arranged by an eye plate 16, and a wire 18 is hung at the lower end thereof. One warp yarn 19 is inserted through each of the arrow wires 18, and the warp needles 15 are selectively caught by the knife 14 by energizing the solenoid coil 11, and the knife 14 is pulled up to a predetermined position. The warp yarn 19 is lifted upward to open, and the weft yarn is inserted into the opened portion, whereby an arbitrary pattern is woven.

Now, assuming that a landscape landscape image as shown in FIG. 3 is used as the design drawing 1A, the fabric size is 2 m long and the width is 4.0 m.
When weaving a pattern cloth of a certain degree, first, after determining how many dots to read the design drawing 1A on the screen of the computer 3, the original is set on the image scanner 2 and read. Next, as described above, the computerized information processing such as color correction and texture correction is performed on the computer.

Assuming that the loom width of the jacquard machine to be used is 1
If the length is 40 cm, naturally, it is not possible to weave the pattern woven fabric of the above-mentioned size in the one-pass weaving process. Therefore, in the present invention, as shown in FIG.
Into strips divided into blocks A, B, C in three (4.0 m /
1.4 m 3). Then, the pattern information signal sent from the floppy disk 5 to the direct jacquard machine 4 is continuously transmitted to the direct jacquard machine 4 in block units such as A block, then B block, and finally C block by transmission control programming. I will send it. Therefore, the pattern paper information sent to the direct jacquard machine 4 is serially sent in the order of A → B → C as shown by the solid line in FIG. 1, and corresponds to the width n in the pattern paper information. The information controls the warp and the weft for the width of the loom of 140 cm, and the fabric is sequentially and continuously woven by the one-pass weaving process.

The woven textured fabric is cut into each block picture, and for example, as shown in FIGS. 5 and 6, the textured fabrics 7A and 7B for each block are sewn to each other to form one large size sheet. The design crest fabric is completed. It should be noted that each of the emblems 7A and 7B may be arranged in a hanging curtain without being sewn together and may be displayed in the hanging room.

When the design drawing 1A is divided into three blocks, it is desirable to divide them into blocks so that mutual blocks have an overlap margin m. In this way, if there is a margin for overlapping the same pattern in the stitched portions of the block woven fabrics 7A and 7B for each block, mutual stitch pattern displacement due to stitching is eliminated even when stitching as shown in FIGS. 5 and 6, for example. Further, when it is attached to a wall or put on a frame for decoration, as shown in FIG. 7, pattern cloths 7A and 7B are overlapped so that the patterns match each other, and the middle of the overlapped portion is cut by a cutter 20. As a result, it is possible to cut the patterns so that the patterns match each other, and in the state of being decorated, the cutting boundary lines are almost unrecognizable.

[0016]

As described above in detail, according to the present invention, the weaving process for large-sized decorative crest fabrics is simplified, and the weaving process is simplified and speeded up. It is possible to prevent picture misalignment from occurring with each other.
