DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming a pattern that can form a pleasing curtain with good appearance without collapse.

[0002]

2. Description of the Related Art A conventional pattern forming method for a curtain with a fold is as follows.
On the outside of the two sheets of paper that are superimposed on the size of the curtain fabric, arrange the pillars that are arranged in parallel according to the direction of the curtain fold so that they are alternately interposed between the two sheets of paper. Then, these columns are stuck to the outside of the pattern, and these columns are pushed into the pattern of the other party to bend so as to form a corrugated fold, and the folds are fixed using steaming, and each is elastically corrugated. It is formed into a strong paper pattern.

[0003]

As described above, since the conventional forming method merely forms the folded portion of the pattern forming the curtain fold with the columnar body, the folded portion of the pattern and the folded portion are formed. It does not have a part that forms a continuous flat part. In the foldable curtain pattern formed by such a method, the flat portion is not fixed at the time of molding,
The surface is in a wavy state, and naturally, the two patterns having the same shape are overlapped with each other, so that the surface becomes irregular and irregular.

[0004] Further, if there is no molded portion serving as a guide in the flat portion of the pattern, even when the fold shape of the pattern is fixed, the forming tool and the pattern cannot be integrated, resulting in an unstable fixation. It has a disadvantage that it is hard to be.

[0005] In particular, as the interval between the folds of the curtain is increased, the proportion of the flat portion is increased, and the appearance of the curtain at the time of finishing is poor. It is the cause.

In view of the above, the present invention prevents a flat portion of a formed paper pattern from becoming uneven, allows a desired shape to be easily and accurately formed, and has a good-looking fold without a shape collapse. It is an object of the present invention to provide a method of forming a pattern paper capable of forming a curtain with a cover.

[0007]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention has a bent portion having a cross-sectional shape forming a folded portion of a pattern, and the pattern is provided on both sides of the bent portion continuously with the bent portion. Forming such that the bent portion of the forming tool formed of a long body having a straight portion forming a flat portion alternately comes into contact with the pattern from above and below with the two patterns overlapped with the size of the curtain fabric. The molds are arranged up and down in the width direction of the pattern, each mold is pushed into the opposite side, the molds are arranged in a horizontal line, and the pattern is curved into a cross-sectional waveform. Then, the pattern is removed from the molding tool, and the pattern is dried.

[0008]

In order to explain the operation of the present invention, the bent part of the forming tool is abutted from above and below with two sheets of paper being overlapped with the size of the curtain fabric, and the forming tool is pushed to the opposite side and the forming tool is moved sideways. When aligned, the pattern curves into a cross-sectional waveform.

Thereafter, water is sprayed on the pattern to tightly tighten the forming tool and the pattern. By spraying the water, the forming tool and the pattern become familiar with each other, and the molding is facilitated. Thereafter, the pattern is removed from the molding tool, and the shape along the molding tool is fixed by drying the pattern.

At the time of molding, the molding tool, which is a long body, has a bent portion having a cross-sectional shape forming a folded portion of the pattern, and a linear portion forming a flat portion of the pattern on both sides of the bent portion. Therefore, not only the folded portion but also the flat portion is formed by the forming tool, and the flat portion has a smooth surface without unevenness, and the whole becomes a regular fold-shaped pattern along the forming tool.

When the shape of the bent portion of the molding tool is formed in an arc shape, the pattern becomes a gently bent shape. When the bent portion is sharp and the straight portion is tapered, it becomes an acute bent shape. Also, by changing the length of the linear portion of the forming tool, various shapes of patterns can be freely formed.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the method of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a molding tool and a pattern used in the present invention. The molding tool 1 is a long body made of a material such as cardboard, plastic, wood, and aluminum, and has a length slightly longer than the curtain length. The long body may be hollow depending on the material.

The cross section of the elongated body has a bent portion 1A forming a folded portion 2A of the pattern 2, and a straight line forming flat portions 2B of the pattern 2 on both sides continuous with the bent portion 1A interposed therebetween. It has a portion 1B.

As the pattern 2, kraft paper for heat resistance is used, and two kraft papers each having a size corresponding to the size of the curtain fabric are laminated and used. The method of forming the pattern is such that the bent portion 1 of the forming tool 1 is sandwiched from above and below the two superposed patterns 2.
The forming tools 1 are arranged in the width direction of the pattern 2 so that A contacts.
At this time, the forming tools 1 are arranged such that the forming tools contacting the upper pattern and the forming tools contacting the lower pattern are alternately arranged (FIG. 2).

Next, each forming tool 1 is pushed toward the opposite side, and the forming tools 1 are arranged in a horizontal straight line, and the pattern 2 is bent into a cross-sectional waveform (FIG. 3).

Next, water is sprayed on the pattern 2 to make the forming tool 1 of the pattern 2 easy to adjust to, and the pattern 2 and the forming tool 1 are brought into close contact with each other and a band 3 or the like is fastened at several places in the length direction of the pattern 2. After tightening with a clothing (Fig. 4) and leaving for several hours,
Is removed, and the pattern is fixed by drying the pattern 2 in the sun or in a vacuum steam oven, and the forming of the pattern 2 is completed (FIG. 5).

Although the shape of the bent portion 1A of the molding tool 1 is various, a gentle turn portion 2A or a fine turn portion 2A is formed depending on the size of the arc, and the bent portion 1A has a sharp shape and a straight line portion. If 1B is tapered across the bent portion 1A, an acute-angled folded portion 2A is formed.

As described above, using the formed pattern 2,
It is conventional that the curtain fabric is sandwiched between the pattern papers 2, converged, clamped with a band-shaped paper, and then molded, and then vacuum-set with steam in a vacuum steam pot to mold the curtain.

[0019]

According to the present invention, not only the folded portion of the paper pattern but also the left and right flat portions continuous with the folded portion are formed along the forming tool. It becomes an orderly shape with the tool. Therefore,
Since the unevenness of the flat portion is eliminated as in the related art, the folds of the curtain formed by the process are not collapsed, and the foldable curtain has a good appearance. Also, by changing the shape of the bent portion and the angle and length of the linear portion of the forming tool, patterns of various shapes can be accurately and freely formed, and is a useful invention.
