It relates to a weaving device for weaving edge portions of both ends of a woven fabric of the present invention.

Conventionally, for example, as known from Japanese Utility Model Laid-Open No. 40-1422, two transformer bobbins are installed on a rotating body, and the rotating bobbin rotates and rotates simultaneously by two rotation bobbins. The metamorphosis device is known to be configured to twist each other whenever the mouth opening and closing of the toilet is known.

Since the attachment position of the metabolic bobbin is determined in such a mechanism of the mechanism, the opening angle of the metabolism is determined when it is installed at a predetermined position. Therefore, since the looms do not necessarily coincide with the opening angle of the local warp yarn, in particular, in the case of looms in which the tip of the weft yarn is in a free state, the bowel yarns interfere with the weft yarns and cause a false mouth. In addition, the weft thread may pass along the lower slope while passing the upper slope while the inclined opening is necessary, for example, when the weft device is installed so that the yarn is opened based on the lower slope of the local inclined yarn. If the upper slope is changed to pass through the upper slope, the upper yarn interferes with the weft, causing a defect that causes a lot of upper misses. In addition, in the case of the so-called post-shape type installed in the rear of the tilling frame, it is necessary to change the installation position of the strainer by changing the number of the tilling frame. As the opening angle of not only changes every time, but also the number of healds used in local caliber increases, and the declination device moves backward, the opening angle of the rim becomes smaller and smaller than the opening angle of the local sloping yarn. In addition to interference with, for example, the lower slope itself is positioned above the lower slope of the ground slope, increasing interference with the weft. In addition, some looms are designed to close the top slope above the warp line and to close below the warp line in order to improve the quality and texture of the fabric. However, since the above-described deformable device opens the metamorphosis by the rotational movement, if it is closed near the inclined line, it is different from the closed position of the local inclination, which causes the formation of the deterioration portion. If, for example, the declination device is installed such that the side slope is closed at the bottom of the slope line in the case where the ground slope is closed at the bottom of the inclined line, there is a defect that cannot be adapted to this if the ground slope is changed to close at the top of the slope line.

The present invention is provided with two toilet bobbins are installed on the rotating body and the rotary bobbin is rotated by the rotation of the rotating body, and the two or more twisting devices are installed to move up and down from the side of the loom. By adjusting the according to the need to prevent the weft interference by the metamorphosis.

Hereinafter will be described based on the embodiment showing the present invention. 1 shows, for example, a deformable device known from Japanese Utility Model Publication No. 40-1422 described above as a schematic diagram, comprising gears on a support shaft 2 fixed to a bracket 3. Two frames (5) and (6), which are supported by the rotating body (4) and accommodate the metabolic bobbin (not shown) on the side of the rotating body, are installed to be rotatable. The metamorphic guides 7 and 8 are attached to each other. The rotating body 4 is connected to the gear 16 on the drive shaft 15 via the gears 9 and 10, the timing pulley 11, the timing belt 12, the timing pulley 13, and the gear 14. Connected and rotated. When the rotor 4 is rotated, the sun gear 19 in which gears and intermediate gears (not shown) on the supports 17 and 18 of the frames 5 and 6 are fixed to the supports 2. Since the frame 5 and 6 are engaged with each other, the frame 5 and 6 rotate together with the rotor 4 in the direction of the arrow and rotate in the opposite direction to the rotor 4. Therefore, the metamorphic guides 7 and 8 move upward and downward in a direction substantially the same as a straight line passing through the center of the shaft 2 to form the opening and closing openings of the metabolism Y drawn out of the metabolic bobbin, and at the same time the two The strands are twisted together. Reference numeral 20 denotes a cover of the knitting apparatus 1, 21 denotes a heald frame for local use, 22 denotes a body, and W denotes the edge of a woven fabric. The attachment ring 23 is supported by the drive shaft 15 via a bearing, and the ring 23 is fixed to the frame 24. Furthermore, the adjustment ring 25 is fitted on the attachment ring 23 and fixed by the bolt 26. Moreover, it is fixed to the frame 24 by the bolt 28 which penetrated the long hole 27 which carved in the adjustment ring 25 and installed. The shaft supporting the gear 14 and the chain wheel 13 is attached to a part of the fixed adjustment ring 25 in this way. Therefore, as described later, when the above-described knitting apparatus is moved in the front-back direction of the loom, the bolt 26 is loosened and the adjustment ring 25 is rotated around the drive shaft 15 to engage the gear 16 with the drive gear 16. 14 and the chain wheel 13 can be followed.

On the other hand, the bracket 30 is fixed to the frame 24 by bolts 31 as shown in FIGS. Bracket 30 is composed of the head portion 32 and the water surface 33, the head portion 32 is a hole 35 through which the adjustment bolt 34 penetrates. The attachment plate 36 is fixed to the front surface of the bracket 30 by two bolts 38 passing through the long hole 37. There is an adjustment plate 39 protruding toward the bracket 30 on the attachment plate 36, where the adjustment bolt is fitted with a screw. Moreover, the rail 40 extended in the front-back direction of the loom is fixed under the attachment plate 36 by the bolt. The movable member 42 is fitted to the rail 40, and since the tapered surface of the fixed member 44 integrated with the movable member 42 and the bolt contacts the tapered surface of the rail 40, the bolt 43 ), The movable member 42 is fixed to the rail 40. Therefore, when the bolt 43 is loosened, the movable member 42 slides in the front and rear directions of the loom along the rail 40 and can adjust the installation position of the deformable device 1 attached as described below. The frame 45 is fixed to the movable member 42 by the bolt 46. The frame 45 extends near the frame opposite to the loom (not shown) and is fixed on the frame constructed in the same manner as above. The rail 47 is fixed to the upper surface of the frame.

The bracket 3 fixing the support shaft of the deformable device 1 has its bottom portion fitted to the rail 47 of the frame 45 and fixed by the bolt 49. Therefore, when the width of the fabric is changed, it is possible to fit the weaving device 1 to the fabric width by loosening the bolt 49 and moving the bracket 3 on the rail 47.

In the above configuration, when the opening of the metabolism Y is made in accordance with the inclined bottom slope, the bolt 38 is loosened and the bolt 34 of the bracket 30 is turned to the left to lower the attachment plate 36. When the fixing plate 36 is fixed by tightening the bolt 38 to the position of (e.g., the scale is easily adjusted), the knitting device 1 is also set to the lowered position, and the yarn is changed in a predetermined opening state. Opening movement of can be performed. In the case where the opening of the yarn is aligned with the top inclination of the local inclination, the bolt 34 can be adjusted to the right in the same manner as described above.

Moreover, this invention can be implemented in shuttleless looms, such as a jet loom, a repier loom, and a gripper loom, in the range of the technical thought.

As described above, the present invention is installed so that two metabolic bobbins can be rotatable on the rotating body, and the toilet which draws out of the two bobbins by the rotation of the rotating body moves upward and downward to perform the opening movement of the metabolic organ. By installing the teeth to move up and down on the side of the loom, you can freely and easily adjust the installation position in the up and down direction of the weaving device. It is possible to prevent the interference of the warp yarns caused by the difference in the opening angle from the ground slope.
