Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a paper pattern for dyeing and an apparatus used therefor. More specifically, the present invention relates to a method that follows traditional hand engraving methods, but which requires no special skill compared to traditional hand engraving methods, and which enables the production of paper patterns in a highly efficient manner, as well as the equipment used to carry out the method.

Generally known methods for producing paper patterns for dyeing include a hand engraving method using a carving blade, a photolithography method using a photosensitive resin, and a method of perforating a heat-sensitive film using infrared rays. The latter two are mechanical production methods, but both require a manuscript that has been traced by color from the original, and this tracing takes a relatively long time. When comparing the time required for carving, the time required for hand carving may be the same or shorter. However, hand carving is a traditional technique that requires particularly skilled technique.

The present invention relates to a method for efficiently producing paper patterns without requiring special skill while taking advantage of the features of the traditional hand engraving method. The production of gauze-hari molds, which have been commonly adopted in recent years in the hand-carving method, involves first making appropriate holes in the paper pattern material and engraving the design through openwork, then pasting paper on the back of the openwork material and cutting out the above-mentioned holes. This is then carried out through the steps of applying gauze over the entire surface of the material, and then peeling off the backing paper. The present invention is different from such a method of manufacturing a gauze type,
The material on which the design is openworked is already covered with gauze, and the gauze remains undamaged during openwork, so that the formation of the above-mentioned ribs is not necessary at all.

In addition, as an invention to achieve the above object, the present inventor uses a paper pattern material in which a sheet-like material with lower heat resistance and heat-fusibility is laminated to gauze, and the pattern of the manuscript is printed on the sheet-like material side of the gauze material. A blunt blade heated to a temperature slightly lower than the melting temperature of the material is applied to cut only the material along the contour of the material, and then, if necessary, the material surrounded by the cut contour is cut. He has completed a method for manufacturing dyeing paper patterns, which is characterized by peeling off sections from the gauze, and is currently applying for a patent (Japanese Patent Application No. 122369/1983). In the case of this previously filed invention, the cut portion of the sheet-like material has a sharp finish similar to the traditional hand engraving method, but the use of a blade inevitably results in a particularly small outline of the design of the manuscript. The cutting operation of the sheet material corresponding to the curved portion tends to become complicated or the efficiency decreases.

The present invention is an improvement on the previously filed invention, and its first gist is to use a paper pattern material in which gauze is laminated with a heat-fusible sheet material having lower heat resistance than gauze. A pointed rod heated to a temperature above the melting temperature of the material and below the heat-resistant temperature of the gauze is applied along the outline of the design of the manuscript on the sheet-like surface of the material, and only the above-mentioned material is melted. The method of manufacturing a paper pattern for dyeing is characterized by cutting the material and then, if necessary, peeling off a portion of the material surrounded by the cut outline from the gauze.

The paper pattern material used in the present invention is a laminate of gauze and sheet material as described above. The latter sheet-like material is required to have lower heat resistance than gauze and heat meltability. Examples of such materials include films of various plastics (eg, polyethylene, polypropylene, polyvinyl chloride, polystyrene), synthetic paper, or impermeable nonwoven fabrics (eg, "Tyvek" manufactured by DuPont). The thickness of the material may be selected as appropriate, and normally a thickness of 50 to 300 microns is suitable as a material for pattern paper. The gauze can be made of various ordinary synthetic fibers that have higher heat resistance than the sheet materials mentioned above (e.g., Tetron, nylon, Nippon Kynor's "Kynol", Teijin's "Cornetx", Mitsubishi Rayon's "Parnel"), natural fibers ( For example, gauze made of silk, cotton) or metal may be used, and fabrics or papers having higher heat resistance and better dye paste permeability than the sheet materials mentioned above may be used.

The pasting of such a sheet-like material and gauze may be carried out in the conventional manner, for example, as described in Japanese Patent Publication No. 51-9324 and No. 51-
9325, No. 51-13045, No. 55-45395, etc. can be referred to. In other words, the adhesive is strong enough to withstand use as a paper pattern, and also strong enough to allow the sheet material to be partially peeled off from the gauze as described later. The two may be bonded together using an adhesive (eg, vinyl acetate emulsion adhesive, vinylidene chloride resin latex adhesive).

The outline of the design on the gauze pattern material may be drawn in a conventional manner. For example, as often used in hand engraving, the pattern material and the manuscript may be overlapped with carbon paper in between and copied. Alternatively, a secondary original having only the outline of the design may be created from the original by a perforation forming technique using infrared printing, and then the outline may be printed on the paper pattern material. In addition,
If the sheet-like material of the paper pattern material is transparent to translucent, the original is superimposed on the paper pattern material and the original is seen through, and the outline of the design is copied onto the paper pattern material, or
Alternatively, you may perform the following work without copying.

To carry out openwork on a paper pattern material having the outline of a design described in this way, the apparatus shown in FIG. 1 may be used. In the drawings, reference numeral 1 denotes a metal rod with a pointed tip, and the sharpness and size of the tip may be appropriately selected depending on the cutting width of the sheet-like material of the paper pattern material. That is, when the cutting width is narrow, a thin and sharp tip is advantageous. A nichrome wire 2 is wound around the base of the metal rod 1 with an insulating paper 3 in between, and the wound portion is surrounded and fixed by a heat-insulating insulator 4 (for example, insulator). The body 4 is attached to a cylindrical grip 5 made of an appropriate material (for example, Bakelite), and the lead wire 6 of the nichrome wire 2 is attached to the grip 5.
It is taken out to the outside through the inside of the metal rod 1, and connected to a power source via a transformer (not shown) for adjusting the heating temperature of the metal rod 1 as necessary. The heating temperature of the metal rod 1 may be within the melting temperature range of the sheet-like material of the paper pattern material, and for example, in the case of the material made of plastic shown in the above-mentioned example, the heating temperature may be 85 to 160°C. Therefore, it is sufficient to use a gauze that is not adversely affected by heat in such a temperature range.

When such a device is applied in a heated state to the sheet-like surface of the paper pattern material, the material is melted and easily cut by the metal rod. Moreover, since the sheet-like material and the metal rod are in a point-contact relationship, the cutting operation of the sheet-like material corresponding to the small curved portion of the outline of the design of the original document can be carried out freely without any hindrance. Note that because the cutting is performed by melting, the sharpness of the cut portion of the sheet-like material is lower than that of the previously filed invention. Therefore, depending on the degree of sharpness required in the cut portion, it may be considered to adopt an appropriate combination of the present invention and the previously filed invention. On the other hand, since the gauze has higher heat resistance than the sheet-like material, it will not be affected by any adverse thermal effects depending on the heating temperature of the metal rod, and will not be damaged by the metal rod. Therefore, when the above device is applied to the paper pattern material in a heated state and the metal rod is moved along the contour of the pattern drawn on the surface of the sheet-like material, only the sheet-like material at the contour portion is cut, and then the sheet-like material is cut at the contour portion. The desired openwork can be performed by peeling off the sheet-like material surrounded by the material with an appropriate tool (eg, tweezers) as necessary. Moreover, since the remaining sheet-like material is adhesively supported by the gauze, there is no need to take any consideration such as providing a ridge as in the conventional hand engraving method.

Therefore, the present invention also includes an instrument for carrying out openwork by hand engraving as described above, and its gist is to grasp a pointed rod-shaped body equipped with electric heating means. It consists in a device characterized by being attached to the body.

Next, the present invention will be specifically explained with reference to Examples.

Example 1 Opaque polystyrene sheet with a thickness of 100μ and 30
Denier, 240# weave Tetron gauze was glued with vinyl acetate emulsion adhesive ("Bond" manufactured by Gisuke Konishi Shoten).
A paper pattern material is used that is laminated using an adhesive with a 1:2 weight ratio of ``KF120'') and methanol at a ratio of 7 g per 1 m ² . Carbon paper is sandwiched between these materials and the original is overlaid to copy the outline of the design. The apparatus shown in FIG. 1 is then applied to the design contour on the polystyrene surface of the pattern material at a metal rod temperature of 90 DEG to 120 DEG C.
Thereafter, the polystyrene sheet surrounded by the cut outline is peeled off using tweezers as necessary to obtain the desired paper pattern.

A transparent polypropylene sheet is used instead of the polystyrene sheet mentioned above, and the outline of the pattern can be seen through simply by overlapping the original on the paper pattern material without copying it. Also, the temperature of the metal rod of the device shown in Figure 1 can be adjusted to 100 to 130℃.
A paper pattern is obtained in the same manner as above except that.
