Description

[Detailed explanation of the invention] (a) Industrial application field This invention relates to a ruler used for sewing the bead of the entrance of the pocket of clothes, women's clothing, jackets, etc.

(b) Problems to be solved by conventional techniques and ideas Conventionally, to sew the beading, as shown in Fig. 7, the beading fabric 12 is overlapped at the pocket entrance position of the garment fabric 11 to adjust the size of the pocket. Sewing the rectangular seam 14 accordingly, make pocket hole cuts 13 as shown in Fig. 8, and pass both left and right ends of the welt fabric 12 through the pocket hole cuts 13 in Figs. 9A and 9B. The welt 15 was sewn by putting it out on the back side of the clothing fabric 11 and adjusting the pattern as shown in the figure, but this required skill to use a sewing machine, and the end G of the welt fabric 12 would fit into the welt 15. As a result, sewing was time-consuming and hindered work progress in the process of sewing clothes. For this reason, a device is used in which parts for sewing welts are attached to a part of the sewing machine, but this device requires skill to operate, and although it is suitable for sewing a large number of the same product, Beads with different standards 15
When sewing a small number of items, the above-mentioned device requires a lot of adjustment and is expensive, so it is not used very often.

The purpose of this invention is to solve the above-mentioned drawbacks and to provide a ruler that allows even a person who is not particularly skilled in sewing with a sewing machine to easily sew the welt 15.

(C) Means and operation for solving the problem To explain this invention based on the drawing, the welt fabric 1 is placed above the pocket hole position on the surface of the clothing fabric 11.
Place the ruler body 1 on top of it with the surfaces of 2 facing downward, and insert the two beaded cores 9, 9'.
Wrap the welt fabric 12 around the
Make it as shown in Figure B, press it on the inside with one presser foot of the sewing machine, and sew the two seams 14 with the sewing machine. Next, pull out the welt cores 9 and 9' from the welt fabric 12 and sew them with the sewing machine. Cut out the center of the attached part to make a pocket hole cut 13, and press the welt fabric 12 into the back side as shown in FIGS. 6A and 6B to finish the welt 15.

This ruler body 1 is made of beaded fabric 1 as shown in Figure 5A.
2 and wrap it around the bead cores 9 and 9',
The bead core 9 that has entered the gap between the folded bead fabric 12,
The part 9' bulges out in a straight line, clearly showing the part to be sewn.

(D) Example The example of this invention will be explained with reference to the drawings.
Reference numeral 1 denotes a main body of a beaded ruler made of a metal plate, a synthetic resin plate, a wooden board, etc., 2 a lower horizontal frame, 3 an upper horizontal frame, and the lower horizontal frame 2 is fixed perpendicularly to the ruler body 1. Reference numeral 4 denotes a bead core presser plate, and 5 uses screws to fix the bead core presser plate 4 to the lower horizontal frame 2.

7 is a rotation axis, 8 is a stop spring, and the upper horizontal frame 3
The ruler rotates upward about the rotation axis 7 as shown in FIG. 1, and is fixed to the ruler body 1 in a perpendicular position by a stop spring.

9 and 9' are beaded cores made of metal or synthetic resin, etc., and are either round rods with a diameter of 5 mm or less, or elongated plates with a polygonal cross section, and the upper and lower ends are curved as shown in Figure 2. When the ruler is placed on the beaded fabric 12, the beaded cores 9, 9' are in close contact with the beaded fabric 12.

Further, when a wide bead 15 or a single bead is required, the bead core 9 of the required width is used instead.

Numerals 10 and 10' are ball edge core fixing holes drilled corresponding to the opposing surfaces of the lower horizontal frame 2 and upper horizontal frame 3, and in the case of the lower horizontal frame 2, the ball edge core fixing holes 9 and 9' are The lower end is inserted into the bead core fixing hole 10, the bead core presser plate 4 is placed on top of this, and it is fixed with screws 5. In the case of the upper horizontal frame 3, the upper ends of the bead cores 9 and 9' are the bead core fixing holes 1.
0', the bead core fixing hole 1 of the upper horizontal frame 3 has been moved upward around the rotation axis 7.
A cutout 6 is provided on the upper surface of 0', and the upper ends of the bead cores 9, 9' are inserted into this cutout 6, and the retaining spring 8 is inserted.
The upper horizontal frame 3 is returned to its original position by the elasticity of the upper horizontal frame 3, and the bead cores 9, 9' are fixed correctly and parallel to each other.

Reference numeral 11 indicates the clothing fabric in which the pocket will be provided, 12 the beading fabric, 13 the pocket hole cut, 14 and 14' the seams to be machined, and 15 the finished beading.

Next, to explain how to use this beading ruler 1, lay the beading fabric 12 face down on the surface of the clothing material to which the beading 15 is to be attached, and place this beading ruler 1 on top of it. As shown in FIG. 5A, the beading fabric 11 is wrapped around the two left and right beading cores 9, 9', and the seams 14, 14' are sewn with a sewing machine to form the state shown in the cross section of FIG. 5B. Next, remove the welt cores 9, 9' and cut the center portions of the left and right seams 14, 14' to create a pocket hole cut 13, and thread both ends of the welt fabric 12 through the pocket hole cut 13. Extrude it to the back side of 11 and prepare the mold as shown in Fig. 6A and B to finish the bead 15.

(E) Effect of the invention As mentioned above, this invention requires wrapping the beading fabric around the beading core and sewing along the straight line of the swollen part with a sewing machine, so it is easy to use even if you are not an expert in sewing using a sewing machine. By using this ruler, you can easily and beautifully finish the shape, making it extremely efficient to sew the bead edges.
