Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to decorative ribbons, particularly ribbons made of a plurality of strips of different colors and materials joined in parallel, and a The present invention relates to a method for producing a ribbon comprising strips of which are overlapped and joined together.

(Prior Art) Conventionally, in order to manufacture a decorative ribbon made of a plurality of strips joined in parallel, the side edges of a pair of strips are butted against each other, and then adhesive tape is applied to both sides of both strips to cover the joints. The strips were pasted together, thereby joining both strips.

When both strips have heat-melting properties, the sides of both strips are overlapped, and a heating needle is inserted into the overlapping portion to form a large number of melting holes, thereby joining the strips.

In addition, when manufacturing a ribbon formed by overlapping and joining each other, both strips are sewn together along both JTs, or, if both strips are heat-fusible, both strips are attached to both ears. Both strips were joined by forming a number of melt holes along the same as described above.

(Problems to be Solved by the Invention) However, the decorative ribbon that cannot be obtained by the conventional manufacturing method has its decorative properties due to the adhesive tape, the melting holes, or the sewing thread, which are the means for joining the plurality of strips. The disadvantage was that it was severely damaged.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for manufacturing a decorative ribbon, which is composed of a plurality of strips joined to each other, in which the means for joining the strips does not impair decorativeness.

(Means for Solving the Problems) The present invention involves stacking a pair of heat-fusible sheets on top of each other, and then thermally cutting both sheets along a straight line in a stiff polymerization region. A method for producing a decorative ribbon is provided, which comprises spreading and pressurizing at least one of the separated bodies.

In addition, the present invention provides a wide sheet having heat-melting properties.
After stacking a plurality of narrow sheets having thermal meltability, the wide sheet and each narrow sheet are thermally cut along the straight line of -・ in the polymerization region, and the resulting product is obtained by thermally cutting. spreading a separated body consisting of a part of the wide sheet and a part of a pair of mutually adjacent narrow sheets;
Provided is a method for manufacturing a decorative ribbon, which is characterized by applying pressure.

Furthermore, the present invention provides a decorative material which is characterized in that after a pair of heat-melting sheets are superimposed on each other, both sheets are thermally cut along two straight lines spaced apart from each other in the overlapping region. A method for manufacturing a ribbon is provided.

The line to be fused can be arbitrarily selected from either a straight line or a curved line.

(Operations and Effects of the Invention) According to the method described in claim (1), by fusing both sheets, parts of these sheets, that is, two pairs of strips that overlap each other, are welded to each other along the straight line, that is, the fusing line. A pair of separators are obtained, and by further expanding each separator, a ribbon is obtained in which a pair of the strips are arranged in parallel and bonded to each other.

The welded portion, which is the mutually joined portion of both strips of the obtained ribbon, occupies an extremely small proportion of the front or back surface of the ribbon compared to the conventional joining means such as adhesive tape or melt holes. Therefore, the mutually joined portions of both strips do not have such an effect as to impair the decorativeness of the ribbon. Furthermore, when the tilt sheet has the same thickness, unlike the conventional ribbon where there is a step between the adhesive tape and the strip or between the strips on the front and back sides, the ribbon obtained according to the present invention has a ribbon on the front and back sides. It can be a smooth surface, consisting of a single strip.

According to the method described in claim (2), a separated body consisting of a part of a wide sheet and a part of a pair of mutually adjacent narrow sheets, that is, a separated body consisting of three strips, is obtained, and the separated body is made of three strips, which are spread out. This results in a ribbon consisting of three strips in parallel. This ribbon also includes a strip cut from the wide sheet;
Similar to the ribbon obtained by the invention of claim (1), the welded portion between both strips cut from both narrow sheets does not impair the decorativeness of the ribbon.

According to the method according to claim (3), a ribbon is obtained consisting of a pair of strips which are superimposed on each other and joined at both side edges. The joints between both strips of this ribbon do not appear on the front and back sides of the ribbon, unlike the conventional suture threads, and are located on both sides of the ribbon where they are not noticeable, so they do not impair the decorativeness of the ribbon. .

(Embodiments) The features of the present invention will become clearer from the following description of the illustrated embodiments.

Referring to FIG. 1, the decorative ribbon 10 according to the present invention is produced by first overlapping a pair of heat-fusible sheets 12.14 with each other, and then combining both sheets 12.14 in a superposition region 16. thermally fused along the straight line.

Both sheets 12, 14 have the same width and thickness, and are opposite and overlapping each other on one side. Both sheets 12 and 14 are selected to have different width dimensions as long as they overlap each other in the longitudinal direction, that is, as long as an overlapping region occurs,
Furthermore, even if the width dimensions are the same, they can be arranged so that they partially overlap rather than the entire surface. Each sheet is made of synthetic resin fabric, knitted fabric, tape, etc.

Both sheets 12 and 14 can be made of the same material or a combination of different materials, and if the sheets are made of synthetic resin fabric, they can be arbitrarily selected from plain weave, satin weave, and twill weave. It may be a combination of the same weave structure or a combination of different weave structures.

Furthermore, both sheets 12, 14 can be of different colors. Examples of material combinations of both sheets include nylon-nylon or polyester, polyester-polyester, acrylic-acrylic, nylon or ester, acetate-acetate, nylon, and ester. Or acrylic type, vinyl chloride type-vinyl chloride type, etc.

Thermal melt cutting in polymerized Li116 is as shown in the example shown in the figure.
This can be done by pressing the hot iron 18 against the polymerization zone 16 while feeding both sheets 12, 14 between the hot iron 18, which has a sharp tip, and the rotating anvil 20 directly below it.

For example, when both sheets 12.14 are made of polyester and nylon, the temperature at the tip of the heating iron 18 and the feeding speed of both sheets 12.14 are set to 300°C and 10 to 30 m.
/minute respectively. It is also possible to use a tool horn connected to ultrasonic generating means in place of the heating iron.

Both sheets 12 and 14, which are fed in the right direction (in the direction of the arrow) in the figure, are moved in the same straight line, that is, in the illustrated example, by pressing the heating iron 18 against the polymerization region 16 of the sheets. It is thermally fused along an imaginary center line extending in the longitudinal direction, and as a result, it is separated into two separated bodies 22.

Parts of the pair of sheets 12 and 14 constituting each separator 22, that is, the pair of strips 24 and 26, are welded to each other at one side edge 28 by thermal welding.

After that, a pair of separated bodies 2 obtained by the thermal cutting
2. Spread each and pressurize. Instead of the illustrated example, the line, that is, the fusing line is set at a position offset from the center line of the polymerization region 16 to one of its side edges, and the object of spreading is only one of the separated bodies having a larger width dimension. be able to.

The expansion of each separator 22 can be carried out manually or from the other side edge 30 of the separator 22 between the two strips 24, 26 in the direction of feed of the separator 22. This method can be carried out by inserting wedge members (not shown) which gradually increase in number and maintaining the parentheses. A press device 3 having a pair of plates 30
It can be expanded by passing between the two plates 30. The separated body 22 that has passed through the press device 32 is formed into a ribbon 10 in which a pair of strips 24, 26 are joined in parallel, and is wound up on a roll 34. Sheet 12.14
The polymerization, fusing, spreading of the separator 22, pressing of the separator 22, and winding of the ribbon 10 can be performed continuously.

In the illustrated example, since the fusing line is set to pass through the center of the polymerization zone 16, the mutual joining portion (joining line) 36 of the pair of strips 24, 26 constituting the ribbon 10 runs along the center of the ribbon in the longitudinal direction. extends in a straight line. For example, if sheets with different widths are stacked so that their center lines are aligned and thermally cut on the straight line, a ribbon with a joining line that is biased toward one side edge can be created. Obtainable.

As shown in FIG. 2, a pair of narrow heat-fusible sheets 40 are placed on a wide heat-fusible sheet 38 at intervals in the width direction of the sheet 38. m of each narrow sheet 40 and wide sheet 38
At the joining area 42, the strips 44 and - which are part of the wide sheet 38 obtained by the thermal cutting are simultaneously thermally cut along one straight line extending in the longitudinal direction.
- A separated body 47 consisting of a pair of strips 46 that are part of a pair of sheets 40 is spread out with a wedge member similar to that described above, and then joined to each other by passing this through a press device similar to that described above. A ribbon 48 consisting of three rows of strips 44,46 can be obtained. Reference numeral 49 indicates a joining line (thermal welding line) similar to the joining line 36 in the above example, which corresponds to the thermal welding line. Instead of using the pair of hot irons 18, the thermal cutting can also be performed using a disc-shaped blade 52 attached to one of the hems 50 at a distance from each other. Each blade 52 is heated by a heat source such as a heater disposed inside thereof to a predetermined temperature at which the sheet can be thermally cut.

The double-edged tool 52 cooperates with a rotating anvil (not shown) similar to that indicated at 11n to pinch the sheet 38, 40 in place and rotates with the shaft 52. In addition, a pair of narrow sheets 4
0 can be arranged so that the opposing side edges touch each other, or so that the side edges overlap each other in the range located between the two blades 52.

As shown in FIG. 3, three or more narrow sheets 40 are arranged on one wide sheet 38, and the overlapping portion of the narrow sheet 40 and the wide sheet 38 is heated using, for example, three or more heating irons 18.
By thermally cutting to obtain a plurality of ribbons, the removed portions 54, 56 that are discarded by thermally cutting can be relatively reduced compared to the example of FIG. 2 in which one ribbon 48 is obtained. Note that if the width dimension of each sheet is appropriately set and the removed portions 54 and 56 are used as a separator for the ribbon 10 obtained in the example shown in FIG.
It is possible to further reduce waste of the sheet.

Next, as shown in FIG. 4a, a pair of heat-fusible sheets 58 stacked on top of each other are thermally cut along two straight lines 60 spaced apart from each other in the overlapping region, so that they are bonded to each other. Overlapping and both sides 59 (4th b
A ribbon 62 is obtained consisting of a pair of strips 61 joined as shown in FIG. By setting each sheet 58 to be relatively wide and manufacturing a plurality of ribbons 62 at a time with three or more fusing lines 60 as in the illustrated example, compared to the case where one ribbon 62 is manufactured at a time. Thus, the amount of removed portions 64 generated can be relatively reduced. Further, as explained in connection with the example shown in FIG. 3, if the removed portion 64 is a separated body used for manufacturing the ribbon 10 in the example of FIG. 1, all of the ribbon 58 can be used for manufacturing the ribbon. Can be done.

The thus obtained ribbon 62 is decorated by deforming it into a cylindrical shape as shown in FIG. It can be used as a string.

According to the thermal melting, that is, the mutual joining by thermal welding of the strips that occurs as the two sheets are thermally melted and the two sheets are cut due to the thermal melting, the thermally welded portion, that is, the joint portion can be made extremely narrow. . Furthermore, in a ribbon consisting of a plurality of parallel-joined strips having the same thickness dimension, the heat-welded portion hardly bulges and has a flat surface as if it were manufactured from one sheet.

The sheets shown in FIGS. 2 to 4a are appropriately selected from those having the same materials, colors, etc. as the sheets 12 and 14 illustrated in the example of FIG. 1. It is also possible to use sheets with different thickness dimensions.
