Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to textiles, non-woven fabrics, papers,
Or, regarding the improvement of the hot melt method of applying various designs (motifs) such as design patterns to leather products, it aims to simplify the process, improve workability, and significantly reduce the cost. .

[0002]

2. Description of the Related Art As a conventional means for applying various designs to textile products, paper, or leather products, motifs obtained through cutting and blade cutting processes in advance have been used.
It is common practice to place it on the upper surface of the cloth to be applied and apply it by means such as sewing or adhesion.

[0003]

However, in the case of the above-mentioned conventional method for producing a design sheet, not only a lot of labor and time are required for producing a motif, but also when an adhesive is used, There is a drawback that peeling is relatively easy to occur by specific use. Also, in particular, in each part of the design, if there is a part where the periphery is carved up like a remote island, or if one design is composed of a plurality of independent discontinuous parts, each of those parts It is necessary to align the parts with each other, which leads to a wide variety of processes,
It requires a lot of manufacturing time and skill of workers, and inevitably results in a large cost.

[0004]

Therefore, in the present invention, the manufacturing process of the design sheet is simplified, and in particular, in each part of the design, there is a part where the periphery is carved like a remote island. Or, when applying a design in which one design is composed of multiple non-continuous parts, it is possible to apply a precise and precise design to the target object in a short time. Specifically, a design sheet in which a backsheet is pasted on the back side in advance is automatically input from the front side by a mechanical method to a module (CPU) as electronic design data and stored as a pattern pattern automatically. After engraving with the engraving device, attach the transfer sheet to the surface of the back sheet with an adhesive that has stronger adhesiveness than the back sheet and is easy to peel off. Thereafter the back sheet is peeled off, placed on target site is subjected to heat-sensitive adhesive on its surface, the
The present invention relates to a hot melt method of a design pattern in which the transfer sheet is peeled off after being heated and pressed under a constant temperature condition.

[Function] A design sheet with a back sheet laminated on the back side in advance is set on the cutting plotter with the front side facing up, and a module and a display device that store patterns such as picture patterns read by a scanner are stored in the cutting sheet. Connect the edited and drawn pattern to the above cutting plotter and mechanically insert a blade on the design sheet to engrave it. Then, except for the engraved part of the design, the unnecessary design sheet is peeled off to leave the design on the back sheet.

After that, a transfer sheet is attached to the whole pattern,
Furthermore, the back sheet is peeled off and the above pattern is transferred onto a transfer sheet, and finally a heat-sensitive adhesive is applied to the entire surface of the pattern from which the back sheet has been peeled off, with the adhesive coated surface facing down. It is placed on the upper surface of the dough, heated and pressed under a constant temperature condition by means of hot pressing or the like to apply hot melt, and then the transfer sheet on the surface is peeled off to complete.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The concrete contents of the present invention will be described below with reference to FIG.
Describing based on the first embodiment shown in 4 to 4, 1 is a design sheet, 2 is a back sheet which is preliminarily releasably overlaid on the back surface, and 3 is a design given to the design sheet 1. The design sheet 1 is preferably a film made of a material excellent in heat resistance such as polyester and machinability, and it is relatively suitable to use a film such as metallic or pearl, or a hollow film or a transparent plain film. In addition, a relatively thin backsheet 2 such as Japanese paper, polyethylene or the like is preliminarily laminated on the back surface of the design sheet 1 via a peelable adhesive. The back sheet 2 in this case may itself be a heat-sensitive adhesive layer.

The design 3 is represented by a portion left on the back sheet 2 by cutting the design sheet 1 by cutting with a blade to remove unnecessary portions from the design sheet 1. In the case of FIG. 1, one pattern (motif) 3 left on the back sheet 2 is composed of an array of a plurality of independent discontinuous portions 3a. Regarding the expression of this design 3, the design sheet 1 is set in the cutting plotter 8 of the mechanical engraving system shown in FIG. 4 with the surface of the design sheet 1 facing upward, and processed by the following procedure.

[0012] The pattern design D to be applied to the blade cutting process cloth or the like is created in advance,
Alternatively, a known pattern or the like is selected and read by the scanner 4, and the module (CPU)
5 is stored as electronic design data, and a pattern edited and displayed by a display device (CAD editor) 6 is connected to the above cutting plotter 8 to automatically mechanically design the pattern D on the design sheet 1. Engrave the pattern corresponding to the design data of.

Unnecessary portion removal process of the design sheet Next, the design sheet is peeled off, leaving the portion of the picture pattern D represented by the engraving on the back sheet, and the unnecessary portion around the design is peeled off and removed on the back sheet 2. Leave pattern 3 on. In the case of the pattern 3 of FIG. 3, the unremoved portion 3c that is engraved and left behind
Are held by the back sheet on the back side. In addition, in FIG. 4 described above, 7 indicates a check plotter for confirming the input picture pattern 3.

Design Transfer Process Next, after a transfer sheet (not shown) is attached to the entire surface of the design 3, the back sheet 2 is peeled off and the design 3 is transferred onto the transfer sheet. The transfer sheet used in this case is preferably a polyethylene or other film having heat resistance, and the pattern 3
It is necessary to previously apply an adhesive agent having a stronger adhesive force than the adhesive surface of the back sheet and easily peeling to the surface to which is transferred.

A heat-sensitive adhesive is applied to the entire surface of the design 3 applied to the hot-melt process transfer sheet, and with this surface facing down, positioning is performed on the target textile product, nonwoven fabric, paper, leather product, or the like. Then, the transfer sheet is heat-pressed on the transfer sheet under a constant temperature condition by a known hot press, and the heat-sensitive adhesive applied to the back surface of the pattern 3 is fused to the fabric surface at the target location. After the pattern 3 is shown at the target location, the transfer sheet on the surface is peeled off and completed.

As a second embodiment of the present invention, although not shown in the figure, a heat-sensitive adhesive is applied to the surface of the design sheet 1, or sheets having a heat-sensitive adhesive action by themselves are stuck together. At the same time, the backsheet material that has been peeled back on the back side is
The same material as the transfer sheet used in the process of the first embodiment, which is not affected by heat, is used. When the design sheet lined with such a backsheet undergoes the same "blade insertion step"-"unnecessary portion removal step of the design sheet" as in the first embodiment, the "design transfer step" is omitted. It is possible to carry out the “hot melt step” immediately.
