Abstract

PURPOSE:To punch out two kinds of figures by overlapping a substratum film having No.2 adhesive layer over a widely extended mask basis having No.1 adhesive layer on its undersurface, punching off the specified figure and by overlapping thereupon a superstratum having No.3 adhesive layer with weak adhesive force. CONSTITUTION:A three-ply mask defoliated from a defoliation base board is affixed to the face of a material to be carved A, and tear is made by pulling the ends of the superstratum film 6 and substratum film 4. Now the intended figure etc. is affixed in double layer as a mask basis 2 and substratum film 4 according to the template, and a pattern consisting of the mask basis 2 having No.1 adhesive layer 1, the No.2 adhesive layer 3 and substratum film 4 is affixed to the side A of the material to be carved, to be followed by carving by means of sandblasting. Then abovementioned torn three-ply mask is affixed to the face of material to be carved B, and only the superstratum film 6 is torn to cause appearance of the surrounding figure for the specified figure. Thus opposite carvings are obtainable from the same pattern.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sandblasting engraving method performed by masking a surface to be engraved.

Conventionally, the engraving method using sandblasting is a well-known method in which masking is applied to the surface of glass, stone, wood, various metals, hard resins, etc.; This was done by measuring the dimensions of a sheet and manually pasting it onto the surface to be engraved little by little. For this reason, it has disadvantages such as requiring a certain amount of skilled manpower, being time consuming and inefficient, and resulting in high costs.

The present invention has succeeded in solving these various drawbacks all at once, and is an epoch-making method that not only allows anyone to easily mask without any need for skilled labor, but also allows the mask base material to be used without wasting it. This is a sandblasting method using a three-layer mask.

The present invention provides a first adhesive layer 1 on the lower surface in a sandblasting method in which various masks are applied to the surface of the material to be engraved.
The lower layer film 4 provided with the second adhesive layer 3 is superimposed on the mask base material 2 on the floor surface provided with the mask base material 2, and a predetermined figure such as a predetermined figure is punched out, and the above-mentioned The upper layer film 6 provided with the third adhesive layer 5 having a weaker adhesive force than the second adhesive layer 3 is stacked to form a triple layer.

A sandblasting method in which the punched figures of the mask base material 2 and the lower film 4 of the mask are masked onto the surface A of the engraved material, and the outer 117 figures remaining on the mask base material 2 and the lower film 4 of the mask are masked. This is a sandblasting method using a triple layer mask in which the surface of the material to be engraved B is masked and the upper film 6 is peeled off.

An embodiment will be described below based on the accompanying drawings.

The mask base material 2 on the floor surface with the first adhesive layer 1 provided on the bottom surface and the ultra-thin lower film 4 provided with the second adhesive layer 3 are superimposed on the release paper on the floor surface to form a predetermined circular shape. A pole having a pattern, a rectangular pattern, a polygonal pattern, a wave pattern, a flower pattern, etc., punched out and a third adhesive layer 5 having a slightly weaker adhesive strength than the second adhesive layer 3 on the upper surface of the lower film 4. The thin upper layer film 6 is stacked to form a triple layer, and the mask base material 2 and lower layer film 4 of the mask are formed into a predetermined arbitrary pattern such as a circular pattern, a rectangular pattern, a polygonal pattern, a wave pattern, a flower pattern, etc. A sandblasting method in which the figure is masked on the surface A of the engraved material.

A sandblasting method using a triple-layer mask is used in which the contradictory shapes of the outer garden 7 remaining on the mask base material 2 and the lower film 4 of the mask are masked onto the surface of the material to be engraved B, and only the upper film 6 is peeled off and processed. be.

Next, how to use it will be explained. Paste the three-layer mask peeled off from the release mount onto the surface of the material to be engraved A,
By holding the edges of the upper layer film 6 and lower layer film 4 and gradually peeling them off, the predetermined shapes, etc. are formed into two layers, the mask base material 2 and the lower layer film 4, according to the cut shapes, and are transferred to the surface of the material to be engraved A. It is pasted to reveal a predetermined figure, etc., which is the original purpose. That is, the surface of the object to be engraved A has a first plate on the lower surface.
A predetermined pattern formed by a mask base material 2 having an adhesive layer 1, a second adhesive layer 3, and a lower film 4 is attached, and the predetermined pattern is engraved by a sandblasting method.

Next, the mask base material 2 having the first adhesive layer 1 on the remaining lower surface outside the predetermined shape @ 7 that has been peeled off, the second adhesive layer 3, the lower layer film 4, and the upper layer film 6 having the third adhesive layer 5. Triple layer mask material, i.e. the punched side used in the blasting method described above.

The mask part with the remaining contradictory patterns is separated from the engraving material B.
By attaching it to the surface of the mask and peeling off only the upper layer film 6, the two-layer mask material of the mask base material 2 and the lower layer film 4 can be attached and exposed as a figure outside the predetermined figure on the workpiece to be engraved. Sandblasting method In this case, the mask base material can be used effectively and without waste.

In other words, by punching out various patterns on the mask material on the floor, two films are used, and by taking advantage of the difference in adhesive strength, two contrasting types of punched and punched parts are created. It allows shapes to appear and be used effectively.

As explained above, by adding another film to the mask base material and using it as a triple mask material, it is possible to engrave contradictory patterns with the same pattern, creating a synergistic effect.
The present invention has extremely significant and significant effects, such as the punching process, which always produces the same pattern without dimensional deviations, has high precision in measurement, is efficient, and can be manufactured at low cost. It is something.
