It comprises a first strip and a pair of second strips extending in the longitudinal direction of the first strip and having side portions respectively joined to the first strip on both sides thereof. The second strip can be joined by heat sealing, and preferably, the first strip and the second strip are made of synthetic fiber fabric or chemical fiber fabric, respectively. A wire can be placed in the space defined by each second strip.

In the method for forming a ribbon according to the present invention, a heat-meltable first strip is superposed on a pair of heat-meltable second strips spaced apart from each other, and each of the first strips is formed. Folding the sides and one side of each second strip back to the same side and heat sealing both sides of each second strip to the first strip. Prior to folding back each side of the first strip, a wire may be placed on the first strip along and near each side of the first strip.

In another method of forming the present invention, a first heat-meltable strip is placed on a pair of second heat-meltable strips spaced from each other such that each edge of the first strip is The second strips are overlapped so as to be located between both edges, one side of each second strip is folded back to the same side, and both sides of each second strip are heat-sealed to the first strip. Including that. Prior to folding back one side of the second strip, wires may be placed on the first strip or the second strip along the vicinity of each edge of the first strip.

[0007]

According to the invention, a second strip extending in the longitudinal direction is arranged on each side of the first strip and both sides of the second strip are connected to the first strip. Since the second strip is joined on both sides, the second strip covers a part of one surface of the first strip, its edge, and a part of the other surface, and is seen in a cross section. Presents a loop shape. Therefore, the second strip has a three-dimensional edging, and is greatly different in shape, texture, and the like from the conventional edging that is a flat edging. From this, a ribbon with higher decorativeness can be realized. Further, the second strip can be arbitrarily selected from materials and colors different from those of the first strip, which can further enhance the decorativeness of the ribbon.

The joining of the second strip to the first strip can be easily performed as compared with the conventional overcasting by suturing, adhesive, heat sealing or the like. Particularly, according to the heat sealing, the first and second strips can be joined more easily and in a shorter time by using the conventional heat sealing device. Further, in the case of the heat sealing, it is desirable that both the first and second strips are synthetic fiber woven fabrics or chemical fiber woven fabrics that are easily melted by heat. Furthermore, if the wire is arranged in the space defined by the second strip, the wire bends when the ribbon is bent, and the bent state is maintained. A part can be formed into various shapes. Therefore, the ribbon has higher decorative performance.

Further, according to the present invention, the first strip is superposed on a pair of second strips spaced apart from each other, and each side portion and each second strip of the first strip are overlapped.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIGS. 1 and 2, a ribbon according to the present invention is shown generally at 10. The illustrated ribbon 10 has a heat-meltable first strip 12 and a pair of heat-meltable second strips 14. The second strip 14 has a width dimension smaller than that of the first strip 12. The two second strips 14 each have side portions 20, 22 which extend in the longitudinal direction of the first strip 12 and are joined to the first strip 12 on its front and back sides 16, 18 respectively. The joint portion of the first and second strips 12 and 18 is indicated by reference numeral 24 (see FIG. 1).

In the illustrated example, the first strip 12 comprises a fabric of synthetic fibers such as polyester, nylon, etc., and the second strip 14 comprises a fabric of chemical fibers such as acetate. On the contrary, the first strip 12
And the second strip 14 may be the chemical fiber fabric and the synthetic fiber fabric, respectively. Alternatively, again, both first and second strips 12, 1
Both 4 can be the same fabric, that is, the synthetic fiber fabric or the chemical fiber fabric. Both fabrics have the property of melting when heated.

Further, in the example shown in the drawing, the first with a large width dimension is used.
Each side 26 of the strip and one side 20 of each second strip having a smaller width dimension are superposed on each other with their edges aligned, and together on the side of the surface 16 of the first strip 12. It is folded back. One side 20 of the folded back second strip faces the other side 22.

A portion of the side portion 26 of the first strip, a portion of one side portion 20 of the second strip, the remaining portion of the first strip 12, and the other side of the second strip, which are superimposed on each other. A part of the portion 22 is heat-sealed together. That is, these parts are heat-melted and integrated with each other (however, the joining point 24
Is shown only in FIGS. 1 and 4 for convenience of drawing. ). Thus, one side 20 of the second strip is substantially joined to the surface 16 of the first strip via the side 26 of the first strip and the other side 22 is the backside of the first strip. It is joined to 18.

Both second joints joined to the first strip 12.
Each of the strips 14 of the first strip 12
Frame the These edgings cover the edges of the first strip 12 and extend from one of its two sides to the other, in the form of a loop in cross section, which makes the ribbon 10 three-dimensional, which is the decoration of the ribbon 10. It acts to enhance sex. Both strips 12 and 14 can be selected in any color. Also, both strips 12, 14
The woven structure of can also be arbitrarily selected. For example, it may have an organdy or a mesh-like woven structure. Thereby, the decorative effect of the ribbon 10 can be further enhanced.

The heat seal is, as shown in FIG.
It is desirable to have a region 24 that is part of the side including the edges of each side 26 of the first strip and part of the side including the edges of each side 20, 22 of the second strip.
According to this, the edge is heat-melted by the heat sealing, and the fray of the thread from the edge is prevented.

Further, as shown in FIG. 3, without folding back both side portions 26 of the first strip 12, only each second strip 14 is folded back and both side portions 20, 22 of each second strip are heated. It may be joined to both surfaces 16 and 18 of the first strip 12 by a seal, respectively. Thus, in this example, both sides 20, 20 of the second strip are
Two of the first strips each have a portion 22 directly
It is in contact with Nos. 6 and 18 and is melted and fixed to the surface (However, for the sake of drawing, the fixed state due to melting is not shown).

In the example shown in FIG. 3, the first strip 12
Each edge of is spaced from the curved inner surface created by the folding back of each second strip 14, but in lieu of this,
Each edge of the first strip 12 abuts the curved inner surface of the second strip 14 or alternatively the first strip 12
A part of each side portion 26 may be curved along the curved inner surface of the second strip 14.

Further, in the example shown in FIGS. 1 to 3, both edges of both sides 20 and 22 of the folded back portion of the second strip 14 are opposed to each other, but these edges do not face each other and extend in parallel. You may do it.

Both first and second strips 12, 14
The joining by heat sealing can be easily performed by heat conduction heating with a heat jig or a heating element, dielectric heating, ultrasonic heating, or the like. Both strips by heat sealing 1
The joining of the two and the strips 14 and 14 is made of the synthetic fiber woven fabric or the chemical fiber woven fabric.
For example, when both strips 12 and 14 are made of a thermoplastic film, and when one and the other of both strips 12 and 14 are made of synthetic fiber non-woven fabric or chemical fiber non-woven fabric, both strips 12, 14,
One and the other of which respectively consist of a thermoplastic film and said synthetic fiber fabric or said chemical fiber fabric, and both strips 12, 14
This is possible when one and the other are made of a thermoplastic film and a non-woven fabric of the synthetic fiber or the chemical fiber, respectively.

Both strips 1 by heat sealing
2,2 joining is also possible if at least one of the two strips 12,14 consists of a natural fiber fabric. However, a thermoplastic resin is impregnated in a portion to be heated of the natural fiber woven fabric or a tape made of the thermoplastic resin is attached.

As shown in FIGS. 1 and 2 and FIG.
The wire 28 is arranged in the space defined by the folded second strip 14. However, in the example shown in FIGS. 1 and 2, the wire 28 is arranged in the space defined by the side portion 26 of the first strip 12 surrounded by the second strip 14. The wire 28 can be arranged as needed.

The wire 28 imparts shape retention to the ribbon 10. Further, for example, when the ribbon 10 is bent, the bent state can be maintained. Therefore,
When decorating an article, it is possible to shape a portion of the ribbon 10, which further enhances the decorative performance of the ribbon 10. Instead of the metal wire 28, a plastic wire (tex) can be used.

The second strips 14 are joined to the first strips 12 by stitching instead of the heat sealing.
It is possible to use an adhesive or the like. When using the suture, the adhesive, etc., the material of the first and second strips does not matter.

The ribbon 10 shown in FIGS. 1 and 2 has the structure shown in FIG.
, The first strip 12 is superposed with its edges aligned on a pair of second strips 14 that are spaced apart from each other, and each side 26 of the first strip and each second strip 14 are It is formed by folding back the one side portion 20 to the same side (the side of the surface 16) and heat-sealing the both side portions 20 and 22 of each second strip to the first strip 12, respectively. The wire 28 is placed on the first strip 12 along and near each side 26 of the first strip prior to folding back each side 26 of the first strip.

The heat seal is, for example, a disc-shaped heating element rotatable about a horizontal axis in a longitudinally continuous region 24 including the edges of the folded side portions 20 of each second strip 14. This is done by pressing the peripheral surface of 30 and moving both strips 12 and 14 in the longitudinal direction. As a result, the regions 24 of both strips 12 and 14 are melted and integrated.

Also, the ribbon 10 shown in FIG. 3 is formed by placing a first strip 12 on a pair of second strips 14 that are spaced apart from each other such that each edge of the strip is on either side of each second strip 14. Overlaps centered between the edges, preferably between the edges, only one side 20 of each second strip 14 is folded back to the same side (the side 16 of the first strip) and the second A portion of each side of strip 14 and a portion of each side of first strip 12 are heat sealed in the same manner as described above. The wire 28 is the second
Prior to folding back each side 20 of the strip, it is placed on the first or second strip 12 along and near each edge of the first strip.

In any case, the ribbon 10 can be easily formed in a short time, and the productivity of the ribbon 10 is high.
