Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite paper for a stencil which can obtain a stencil having a complicated line drawing or pattern by an inexpensive and simple method. The present invention also relates to a stencil manufacturing method using the stencil composite paper.

[0002]

2. Description of the Related Art Stencils capable of printing and drawing desired line drawings or patterns by a simple method are widely used in various fields for business use, and in recent years, are also commercially available for children's toys.

The following three methods have been conventionally known as methods for manufacturing such a stencil. First,
Stencil paper or plastic film is sandwiched between male and female molds with desired line drawings or patterns,
This is a method of die cutting by press working. Next, place the paper or plastic film that will become the stencil on a flat plate,
This is a method in which a desired convex line drawing or pattern is formed on one surface of a flat plate called a die, and the die is pressed by pressing from above. Further, a die-cut substrate having a desired convex line drawing or pattern formed by etching on a metal plate such as lead is prepared, a polyvinyl chloride film is placed on this substrate, and the die is cut by heating the substrate in a pressed state. Method (thermal cutting method).

[0004]

SUMMARY OF THE INVENTION The above-mentioned conventional method has the following problems.
Each has the problems to be improved as listed below.

[0005] First, the press working method is excellent in that a complicated and fine line drawing can be formed, but it requires the production of a male mold and a female mold for each required stencil. In other words, there is a problem that the delivery time from order to product shipment requires a long time.

[0006] Next, the method using the revolving mold can satisfy the requirements of cost and delivery time if the line drawing is simple and large, but cannot produce a stencil having complicated and fine line drawing. Have a point.

Furthermore, the heat cutting method is an excellent method in that it can satisfy requirements such as cost and delivery date and can form complicated and fine line drawings. However, when the heat cutting method is applied, there is a problem that the stencil material is limited to a polyvinyl chloride film. In addition to that, in addition to the remaining mold part left on the board after the mold removal,
There is a problem that the molten residue may remain in a sticky state. In such a case, it is necessary to remove the residue each time, which not only complicates the manufacturing work, but also results in the reproducibility of the product in the next and subsequent die removal work if the removal of the residue is insufficient. And the possibility of occurrence of defective products also arises.

The present invention solves the above-mentioned problems of the prior art, and satisfies the requirements such as cost and delivery date, and obtains a stencil having complicated and fine line drawings with good reproducibility by simple operation. It is an object of the present invention to provide a composite paper for stencils.

Another object of the present invention is to provide a method for producing a stencil using the stencil composite paper.

[0010]

Means for Solving the Problems In order to achieve the above object, the present inventor has first focused on a method of manufacturing a stencil at room temperature using a die-cutting substrate prepared by etching, and has repeated studies. And, as a result, it was found that by laminating the mount and the paper for stencil production and compounding, it was possible to prevent the die portion and the like that had been punched out on the die-cutting substrate side from remaining, and further research was further conducted thereafter. result,
The present inventors have found a suitable combination of a mount and a stencil-producing paper for achieving the object of the present invention, and have completed the present invention.

[0011] In order to solve the above-mentioned problems, the present invention provides a stencil synthetic paper, a polyvinyl chloride film or a Japanese paper which is bonded and integrated on a mount made of a Japanese paper or a polypropylene film via an adhesive. A composite paper for stencils.

[0012] In order to solve the above-mentioned problems, the present invention provides a stencil, wherein the composite paper for stencil is brought into contact with a substrate on which a desired convex line drawing or pattern is formed by etching. A manufacturing method is provided.

The term "paper" used in the stencil composite paper of the present invention is not limited to a material, but is used to represent a shape.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The stencil composite paper of the present invention and a method of manufacturing a stencil using the same will be described below with reference to the drawings showing one embodiment thereof. 1 is a plan view of the stencil composite paper, FIG. 2 is a cross-sectional view in the length direction of FIG. 1, and FIG. 3 is a cross-sectional view in the length direction of a modified embodiment of FIG. FIG. 4 is a conceptual diagram for explaining the manufacturing method of the present invention, and FIG. 5 is an explanatory diagram of a method of using a stencil obtained by the manufacturing method of the present invention.

The stencil composite paper 1 is a combination of a backing paper 2 and a stencil paper 3 (hereinafter referred to as “stencil paper”), and these are integrated by bonding with an adhesive 4. ing.

The mount 2 has a desired size and shape determined according to the application, and is made of Japanese paper or a polypropylene film. For example, as a commercial product, Sekisui Application Film (trade name; manufactured by Sekisui Chemical Co., Ltd.) ), N
o. 115 and the like.

The stencil sheet 3 has the same or different shape as the backing sheet 2 and a size equal to or smaller than that of the backing sheet 2. Thus, for example, when the mount 2 is rectangular, the stencil paper 3 can be of the same size or a small rectangle, or it can be square, triangular, circular, or the like.

The stencil paper 3 is a synthetic paper, (weather resistance)
It is made of polyvinyl chloride film or Japanese paper.
Of these, synthetic paper is made of polyethylene as the base resin,
It is produced from wood pulp using polypropylene, polystyrene, polyvinyl chloride or the like. Examples of commercially available products include Yupo (trade name, manufactured by Oji Paper Co., Ltd.).

The stencil composite paper 1 is made of the above-mentioned backing paper 2
And the stencil paper 3 can achieve the object of the present invention. When one or both of the materials other than those described above are used, a desired line drawing or the like can be suitably cut out. Or the backing sheet 2 and the stencil sheet 3 remain on the die-cutting substrate.
Therefore, the composite paper for stencil 1 of the present invention is formed by appropriately selecting from the combination of the materials of the above-mentioned backing sheet 2 and stencil sheet 3, and among them, particularly, the backing sheet 2 is made of Japanese paper and the stencil sheet 3. However, a combination of synthetic papers is preferred.

The stencil composite paper 1 can be manufactured by applying a general lamination molding method such as wet lamination, dry lamination and hot melt lamination. In this case, as shown in FIG.
A part of one side of the backing paper 2 is cut off (see 2a in FIG. 5).
The stencil sheet 3 of the same shape is fitted into the cut-out portion, so that the stencil sheet 3 can be manufactured so as to form the same plane as a whole. Also, as shown in FIG.
The stencil sheet 3 can be manufactured in a state where the stencil sheet 3 is placed on one surface of the backing sheet 2. A notch can be formed in a desired portion of the backing sheet 2 or the stencil sheet 3 so that the stencil can be easily peeled off during use.

Next, an example of a method for manufacturing a stencil using the stencil composite paper 1 will be described with reference to FIGS. First, a die-cutting substrate 10 having a desired convex line drawing or pattern 11 formed on a surface of a lead plate or the like by etching is prepared. At this time, the height of the convex line drawing or the pattern 11 from the surface of the die-cutting substrate 10 is 0.35 in view of the strength.
The limit is about mm. Therefore, the thickness of the stencil composite paper 1 used in this manufacturing method is set to less than about 0.35 mm. In this case, the relationship between the height of the convex line drawing or pattern 11 and the thickness of the stencil composite paper 1 is preferably adjusted in consideration of the relationship between the pressing force during stencil production.

Next, at a predetermined position on the peripheral surface of the roller 15,
The stencil composite paper 1 is attached with the stencil paper 3 facing outward. The stencil composite paper 1 can be attached by a method such as temporarily fixing the peripheral surface of the roller 15 with an adhesive or making the peripheral surface of the roller 15 sticky.

Next, by rotating the roller 15 in the direction of the arrow in FIG. 4, the stencil composite paper 1 is brought into continuous contact with the die-cutting substrate 10 (convex line drawing or pattern 11) in a pressed state. . By this operation, the stencil sheet 3 is cut into a desired line drawing or the like, and a stencil can be obtained.

The stencil 20 thus manufactured
Are still integrated with the mount 2. Therefore, at the time of use, the stencil 20 is peeled off from the backing sheet 2 as shown in FIG. 5, but by peeling in this manner, only the die-cut portion 21 remains on the backing sheet 2 by the action of the adhesive. It can be used as a stencil 20 having a desired mold.
