Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a method for forming a selvage structure in a pile fabric obtained by cutting the middle part of a double fabric, and more specifically, the present invention relates to a method for forming a selvage structure in a pile fabric obtained by cutting the middle part of a double fabric. The present invention relates to a method for forming the selvage structure of the pile fabric, which is woven using a single shuttle, with the opening positions of the threads placed above and below each other.

(Prior Art) Conventionally, a method of manufacturing a pile fabric by cutting the middle part (pile part) of a double-layered fabric is known.

In addition, as an improvement method, there is a method for producing a pile fabric in which the opening positions of the seam threads of the upper and lower fabrics are placed in a vertical relationship with each other, and the wefts are inserted and woven alternately from top to bottom.
This is known from Japanese Patent Application Laid-Open No. 132654/1983.

(Problems to be Solved by the Invention) In the above-mentioned Japanese Patent Application Laid-open No. 132654/1983, a double fabric is obtained by alternately driving one weft yarn into the upper fabric and the lower fabric using one shuttle. The method of cutting the middle part had the following drawbacks.

That is, as shown in FIGS. 10 and 11, the weft 4
is connected from the upper fabric to the lower fabric, so when the middle part is cut, the selvedge weft 14 is also cut at the same time, and the selvedge weft 14 is cut off at the same time, and the warp threads at both ends of the fabric are separated from the weft threads without having a selvage function, causing the selvage to fray. There was a drawback that it was difficult to use.

In order to solve this drawback, Figs. 12 and 13
As shown in the figure, there is a method in which two shuttles for the lower cloth of the upper cloth shuttle are driven in alternately, one each corresponding to the upper cloth shed and the lower cloth shuttle. Two of each must be equipped. The present invention is a method for forming selvage tissue that is effective when a double fabric is woven using only one shuttle box on each side, and the shuttle boxes are moved up and down as necessary.

(Means for Solving the Problems) The present invention provides an upper fabric structure consisting of a sew thread for the upper fabric and a group of weft threads for the upper fabric, and a base fabric structure consisting of the sew thread for the lower fabric and a group of weft threads for the lower fabric. In a method of weaving a double fabric in which a pile yarn is reciprocated between the upper fabric weft yarn group and the lower fabric weft yarn group to form a pile portion, the following This is a method of forming ears using a and b.

a) Supply the upper fabric selvage thread to the woven fabric by the upper fabric guide, and cross the selvage thread group at a position on the opposite side of the fabric between the upper fabric selvage thread group and the lower fabric selvage thread group. The upper fabric guide is made capable of reciprocating motion as shown in FIG. Driving,
Next, the guide for the upper fabric is moved between the upper fabric selvage thread group and the lower fabric selvage thread group to reach the other end of the upper fabric selvage thread group and raised outside the other end, thereby raising the edge thread, After driving the weft yarn for the upper fabric under it, the guide for the upper fabric is again moved in the opposite direction between the upper fabric selvage yarn group and the lower fabric selvedge yarn group, and the process is repeated until it reaches the opposite side of the other end. Weave the selvage of the upper fabric, b. Supply the hem thread for the lower fabric to the woven fabric by the guide for the lower fabric, and then tie the fabric against the basting under the selvage thread group of the upper fabric and the selvage thread group of the lower fabric. The guide for the lower cloth is made reciprocatingly movable so as to cross the group of selvage threads at the opposite position, and the guide for the lower cloth is raised outside one end of the group of selvage threads of the lower cloth, thereby raising the edge threads. The guide for the lower cloth is moved under the lower cloth selvage yarn group, reaches the other end of the lower cloth selvage yarn group, and is raised outside the other end, thereby After raising the yarn and driving the lower cloth weft yarn under it, the lower cloth guide is again moved in the opposite direction under the lower cloth selvage yarn group, and the process is repeated until it reaches the opposite side of the other end. It organizes the edges of the lower cloth.

The present invention is a method of permanently providing selvage tissue, such as the example shown in FIG. 3, in the weave of the fabric itself.

1, 3, and 5 are weft threads of the upper fabric, 2 and 4 are weft threads of the lower fabric, , are upper fabric selvage threads, and , are lower fabric selvage threads.

To explain the selvage structure of the upper fabric, the upper fabric edge thread A extends from right to left, passes under the upper fabric selvedge thread, passes over the weft thread 1 from the front of the upper fabric selvedge thread, and passes over the weft thread 1. Cross the bottom of the fabric selvage thread, pass over the weft thread 3, cross the bottom of the upper fabric selvage thread, and pass over the weft thread 5.
It passes over the

A schematic diagram of this ear tissue viewed from above is shown in the second
Shown at the bottom of the figure. The weave for four selvage threads at the left end of the upper fabric 1 is an example of the selvage tissue of the present invention, and the edge thread A is not knitted together with the selvage thread, but is located below the selvage thread, and is composed of the four selvage threads. It is woven with the weft by coming out above the weft 4 only on both sides of the weft. Further, it is preferable that the selvage yarns and the weft yarns form a weave such as a plain weave or a twill weave.

Next, the present invention will be explained in detail with reference to examples.

FIG. 1 is a side view showing the agent of the present invention,
A double fabric selvage is woven from the upper fabric selvage thread, the lower fabric selvage thread, the upper fabric weft 4, and the lower fabric weft 5.
Upper fabric selvage thread, upper fabric thread heddle, lower fabric selvage thread,
The threads pass through the lower fabric thread heddles and move up and down in the same way as each thread. The number of selvedge threads is preferably about 4 to 10 for each of the upper and lower fabrics.

Note that the pile yarn has been omitted to make the diagram easier to read. The upper fabric guide control thread 8 is interposed between the reed 10 and the heald.
The fabric is suspended from the pulley 11 in a vine-like manner by passing between the upper fabric selvage thread and the lower fabric selvage thread so that the material is held in the loop. The upper fabric guide control thread 8 has the upper fabric edge thread guide 6 attached to its intermediate portion, and moves by the rotation of the pulley 11 while holding the upper fabric selvage thread in its loop. The stitched yarn A for upper fabric passed through the stitched yarn guide 6 also moves entangled therewith.

FIG. 2 is a schematic plan view of an upper fabric according to an embodiment of the present invention. In this example, when a selvage is formed using four upper fabric selvage threads, the upper fabric edge thread guide 6 is made reciprocating across the selvage threads by the upper fabric guide control 8.

Also, almost the same device is used for the selvage of the lower cloth.

That is, as shown in FIG. 1, the lower fabric guide control thread 9 is suspended from the pulley 11 so that 4 to 10 lower fabric selvage threads for forming selvages are caught between the reed 10 and the heald. It will be done. The lower fabric guide 7 is attached to the lower fabric guide control thread 9, and moves while holding the upper fabric selvage thread and the lower fabric selvedge thread in its loop by the rotation of the pulley 11, thereby controlling the lower fabric edge thread. The lower cloth thread B passed through the cloth guide 7 also moves accordingly. The rest is the same as the upper cloth.

(Function) Next, the ear manufacturing method of the present invention will be explained in more detail.

FIG. 4 is a schematic side view of the upper fabric selvedge on the left side when facing the weaving direction when weaving 1 in FIG. 3. Both the upper fabric and the lower fabric are open, and the upper fabric stitch The guide 6 comes out in front of the upper fabric selvage thread in the diagram, that is, to the left in the weaving direction, and rises, and the edge thread A is raised to the same extent as the upper fabric selvage thread that has risen, and the thread below it is raised. Insert upper fabric weft thread 4. FIG. 7 shows this in plan view.

Next, Fig. 5 is a schematic side view when weaving 2 in Fig. 3, in which both the upper fabric and the lower fabric are open, and the lower fabric edge thread guide 6 is used for the lower fabric selvage thread. It is moving from the front of the figure to the other side. At this time, the lower cloth weft 5 is driven into the opening of the lower cloth.

FIG. 8 shows this in plan view.

Next, Fig. 6 is a schematic side view when weaving 3 in Fig. 3, where both the upper fabric and the lower fabric are open, and the guide 6 for the upper fabric thread is on the other side of the figure. The edge yarn A is raised to the same extent as the raised upper fabric selvage yarn, and the upper fabric weft 4 is driven into the upper fabric weft yarn. FIG. 9 shows this in plan view.

Thereafter, the upper fabric stitching thread guide 6 passes under the selvage thread in the same manner and returns to the position shown in FIG. 4, that is, FIG. 7.
Repeat the movement of rising.

The method for forming the upper fabric selvage has been described above, but the lower fabric selvage is also formed in the same manner.

As in the above example, the present invention is applicable to
It is preferable to combine this with a weaving method such as No. 32654 in which the openings of the upper and lower fabrics are located at the top and bottom positions, respectively. Since the lowered upper fabric selvage thread and the lower fabric selvedge thread that have risen intersect, the upper fabric guide control thread 8 becomes an obstacle to the opening of the upper fabric selvedge thread. On the other hand, in the method of weaving with the upper fabric opening and the lower fabric opening positioned vertically, the upper fabric guide control yarn 8 is inserted between the lowered upper fabric yarn selvage and the raised lower fabric selvedge yarn as shown in FIG. A gap can be provided for the passage.

Further, as a method for moving the guides 6 and 7, an example using a pulley and a guide control thread has been shown, but other methods such as a rod-type guide may also be used, and the power can be obtained from the rotation of the loom or from the jiya guard. However, in any case, it is not limited to this embodiment.

(Effects) According to the present invention, even when the pile part of a double fabric is cut using a loom with only one shuttle box on the left and right sides, the above method eliminates the problem of fraying of the edges, and improves quality as well as finishing, inspection, and transportation. The workability of post-processes has improved.
