Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a cloth guide for forming box pleats on cloth.

[Conventional technology]

Conventionally, in order to form box pleats on a cloth W, as shown in FIG. After bending, it was formed by stitching with a two-needle sewing machine using parallel stitches S and S as shown by the two-dot chain line.

[Problem that the invention attempts to solve]

However, the box pleats sewn as described above are not desirable in terms of design as sewn products because two parallel seams appear on the bottom side of the box pleat in Figure 7, which is the front side of the garment. Therefore, the product value as a sewn product was low.

[Means for solving problems]

This idea was made in order to solve the above problem, and it is a cloth for forming box pleats by expanding the pleats of cloth, which are made by linearly stitching pleats with a certain spacing and height, from the inside. The guide tool is composed of a flat substrate, a guide body with a groove that gradually becomes narrower in width and shallower in depth toward the tip, and arranged on the substrate, and a plurality of pieces on the upper surface of the guide body. The position of the groove at the tip is the seam pitch of the pleat.
A positioning plate that is approximately equal to P ₁ and is located at the center of the tip of the concave groove of the guide body, and is formed so that the width of the groove gradually increases toward the tip; A long insertion plate whose width is slightly narrower than the width of the groove tip.

[Effect]

In advance, pleats with a certain spacing and height as shown in Figure 5 are sewn in a straight line using a single needle sewing machine, then the fabric is turned inside out and inserted into the pleats as shown in Figure 6. Insert each insertion plate and let the fabric hang on the insertion plate.In this state, insert the pleats and insertion plate into the groove of the guide body, and insert the seam into the groove of the positioning plate, and then insert the fabric. gradually pull it out to the tip of the guide. As a result, the cloth drawn out from the tip of the guide is bent as shown in FIG. 4, and by feeding the cloth tip to a roller press or the like, a box pleat is formed on the cloth.

〔Example〕

Embodiments of this invention will be described below with reference to the drawings.

1 is a flat substrate, a pair of L-shaped supports 2a and 2b are fixed on both sides of the right end thereof, and a locking rod 3 is supported at the upper end of the support.

4a, 4b, and 4c are guide bodies having the same structure, and the guide body 4a will be explained. Guide body 4a
is bent upward into a U-shape to form a groove 5, and this groove 5 has a high rear end (right end) and gradually deepens toward the tip, as shown in FIG. It is formed so that the depth is shallow, and its width is the same as that of the third and fourth
As shown in the figure, it is gradually narrowed toward the tip, and the inner width of the tip is formed to be slightly wider than the widened width D of the pleat 6 shown in FIG. 5 as shown in FIG. 7. These guide bodies 4a, 4b, 4c are
The grooves 5 are fixed to the substrate 1 so that the distance P ₂ between the center lines X of the widths of the grooves 5 substantially coincides with the pitch P ₁ of the seam portion of the pleats 6 shown in FIG.

7a, 7b, 7c, and 7d are positioning plates, and these positioning plates are arranged on the upper surface of the guide bodies arranged in parallel on the board. By means of these positioning plates, the grooves 8a, 8 are located at positions corresponding to the center line X of the width of the groove 5 of each guide body 4a, 4b, 4c.
b and 8c, and the widths of these grooves are formed to become gradually narrower toward the tip.

Reference numerals 9a, 9b, and 9c are insertion plates having the same configuration, and a bent portion 10 that locks on the locking rod 3 is formed at the right end.
The width of the central portion is narrowed, and the tip portion 11 is formed to be slightly narrower than the width of the groove 5 of the guide body.

This invention has the above structure, and the procedure for forming box pleats using this fabric guide will now be explained.

First, as shown in FIG. 5, for example, three pleats 6 having a constant interval _P1 and height are sewn together using a single needle sewing machine.

Thereafter, this cloth W is turned over, and insert plates 9 are inserted into the pleats 6, respectively, as shown in FIG.
a, 9b, and 9c are inserted, and the entire length of the cloth W is pulled through the insertion plate until their tip portions 11 protrude from the cloth.

From this state, insert the tips 11 of the insertion plates 9a, 9b, 9c into the grooves 5a, 5 of the guide bodies 4a, 4b, 4c.
b and 5c from the wider side, and the bent portion 10 is locked to the locking rod 3 as shown in FIGS. 1 and 2.

In addition, as shown in FIGS. 3 and 4, the cloth W into which the insertion plate has been inserted has its pleats 6 in the grooves of the guide body.
Guide the sewing part so that it enters the groove of the positioning plate, and gradually pull out the tip of the cloth toward the tip of the guide. As a result, the tip of the cloth is formed as shown in Figure 4,
The pleats 6 have the same width on the left and right sides around the stitched portion, forming a box pleat shape.

When the end of the cloth W, which has been bent as shown in FIG. 4, is fed to the tip of the cloth guide tool, for example, to a rotating rotary press, the cloth will be folded as shown in FIG. Then, it is automatically fed to a rotary press and molded as shown in FIG.

[Other Examples]

In addition, in the illustrated embodiment, three pleats are formed into a box pleat as shown in FIG. You can choose.

Further, the press is not limited to a rotary press; box pleats can also be formed by repeatedly pulling out a certain length of cloth and ironing it using an iron or the like.

[Effect of idea]

As described above, in this invention, a cloth with pleats of a certain height sewn together using a single-needle sewing machine is set in the cloth guide of this invention, and then the cloth is pulled out from the tip and pressed. With a chisel, it is possible to form box pleats that are even on the left and right from the seam without requiring the operator's sense of touch, and the box pleats formed as shown in Figure 7 do not show the sewing machine seams on the outside of the garment. This has the effect of improving the quality of sewn products and producing products with high commercial value, and does not require any skill to form box pleats.
Even beginners can form box pleats with high commercial value accurately, and work efficiency is improved.
